"and guitar right handed. She can also play the piano with her left hand while playing the zither with her right. Kurt Cobain, from Nirvana, was naturally left-handed, but Donald Cobain, his father, forced him to write with his right hand. Kurt could write ambidextrous, but mostly wrote right-handed. With respect to tools, ambidextrous may be used to mean that the tool may be used equally well with either hand; an ""ambidextrous knife"" refers to the opening mechanism and locking mechanism on a folding knife. It can also mean that the tool can be interchanged between left and right in"
"younger generations face any such pressure to begin with. Ambidexterity is when a person has approximately equal skill with both hands and/or both sides of the body. True ambidexterity is very rare. Although a small number of people can write competently with both hands and use both sides of their body well, even these people usually show preference for one side of their body over the other. However, this preference is not necessarily consistent for all activities. Some people may for example use their right hand for writing, and their left hand for playing racket sports and eating (""see also:"""
"able to tie with their left and right hands in either single or double knots. This is usually due to factors like the positioning of the surgeon, whether they have an assistant and the angle required to throw and secure the knot. Ambidexterity is also useful after surgery on a dominant hand or arm, as it allows the patient to use their non-dominant hand with equal facility as the limb which is recovering from surgery. Ambidexterity Ambidexterity is the state of being equally adapted in the use of both the left and the right hand. When referring to objects, the"

Examples of ambidextrous footballers include Johan Cruyff, Zinedine Zidane, Santi Cazorla, Glenn Hoddle, Alfredo Di Stéfano, Sócrates, Paolo Maldini, George Best, Michael Laudrup, Ronaldo, Pelé, Pavel Nedvěd, Marc Overmars, Michel Platini, Roberto Baggio, Carlos Valderrama, Bobby Charlton, Zico, Tom Finney, John Barnes, and John Charles Gianluca Pagliuca is cross-dominant. He punches and throws with his right, but kicks with his left. In rugby league and rugby union being ambidextrous is an advantage when it comes to passing the ball between"
"in schools or in jobs where right-handed habits are often emphasized or required. Since many everyday devices (such as can openers and scissors) are asymmetrical and designed for right-handed people, many left-handers learn to use them right-handedly due to the rarity or lack of left-handed models. Thus, left-handed people are more likely to develop motor skills in their non-dominant hand than right-handed people (who are not subjected to left-favoring devices). Right-handers may become ambidextrous due to an injury of their right hand or arm. Ambidexterity is often encouraged in activities requiring a great deal of skill in both hands, such"
"Ambidextrous firearms allows for an identical manual of arms regardless of which hand is being used as primary, which streamlines training (eliminates need to have separate training drill for left handed shooting). Many right-handed people shoot rifles left-handed because they have a left dominant eye, and the opposite also applies. Generally, it is easier to adapt handedness than to retrain eye-gunsight tracking. Regardless, with training, eye dominance can be overridden. ""Old West"" gunfighter Dallas Stoudenmire carried two pistols, and was noted for being equally accurate with either hand. A degree of ambidexterity is required in surgery because surgeons must be"

In boxing, Manny Pacquiao has a southpaw stance in the ring even though he is really ambidextrous outside the ring. Also, in mixed martial arts, many naturally left-handed strikers like Lyoto Machida and Anderson Silva will switch stances in order to counter opponent's strikes or takedown attempts to stay standing. In cricket, it is also beneficial to be able to use both arms. Ambidextrous fielders can make one handed catches or throws with either hand. Sachin Tendulkar uses"
"with right foot or whose left foot isn't dominated, this drastically shorten the time from maximum acceleration to maximum deceleration and left footer possesses a much greater advantages in racing. In tennis, a player may be able to reach balls on the backhand side more easily if they're able to use the weaker hand. An example of a player who is ambidextrous is Luke Jensen. Rafael Nadal uses his right hand for writing, but plays tennis with left. There are many players who are naturally right handed but play lefty and vice versa. Evgenia Kulikovskaya is also an ambidextrous player,"

In agreement with this hypothesis, ambidexterity is also associated with schizotypal and schizophrenic individuals. Three recent studies by Mark Batey and Adrian Furnham have demonstrated the relationships between schizotypal and hypomanic personality and several different measures of creativity. Particularly strong links have been identified between creativity and mood disorders, particularly manic-depressive disorder (a.k.a. bipolar disorder) and depressive disorder (a.k.a. unipolar disorder).

"Laterality The term laterality refers to the preference most humans show for one side of their body over the other. Examples include left-handedness/right-handedness and left/right-footedness; it may also refer to the primary use of the left or right hemisphere in the brain. It may also apply to animals or plants. The majority of tests have been conducted on humans, specifically to determine the effects on language. The majority of humans are right-handed. Many are also right-sided in general (that is, they prefer to use their right eye, right foot and right ear if forced to make a choice between the"

For example, when standing up, the knees are extended. Extension of the hip or shoulder moves the arm or leg backward. When the chin is against the chest, the head is flexed, and the trunk is flexed when a person leans forward. Abduction is the motion of a structure away from the midline while adduction refer to motion towards the center of the body. The centre of the body is defined as the midsagittal"
"subtle deficits in both reading and listening comprehension are almost always present during assessment of aphasia. Because Broca's area is anterior to the primary motor cortex which is responsible for movement of the face, hands, and arms, a lesion affecting Broca's areas may also result in hemiparesis (weakness of both limbs on the same side of the body) or hemiplegia (paralysis of both limbs on the same side of the body). The brain is wired contralaterally, which means the limbs on right side of the body are controlled by the left hemisphere and vice versa. Therefore, when Broca's area or"

The gestures used for pointing and their interpretation vary among different cultures. While studies have observed index finger pointing in infants across a range of cultures, because those studied are also ones where adults frequently use this type of pointing, further study is needed to determine whether these are examples of imitation of behaviors performed by observed adults, or whether it indicates pointing may be biologically determined. In much of the world, pointing with the index"

Sexuality for disabled people is often linked to fetishes and ""freakish excess."" Apotemnophilia is when an individual amputates his own limb for sexual pleasure. A case research done in the Journal of Sex Research states ""Apotemnophillia is related to erotization of the stump and to overachievement despite a handicap."" Little is known about the relationship between sexual pleasure and amputated limbs. This is due to the fetish"
"achieve pure flexion at the joint the deltoid and supraspinatus must cancel the adduction component and the teres minor and infraspinatus the medial rotation component of pectoralis major. Similarly, abduction (moving the arm away from the body) is performed by different muscles at different stages. The first 10° is performed entirely by the supraspinatus, but beyond that fibres of the much stronger deltoid are in position to take over the work until 90°. To achieve the full 180° range of abduction the arm must be rotated medially and the scapula most be rotated about itself to direct the glenoid cavity"
"meet with one in midstance and midswing, beginning the propulsion and terminal swing phases. Upper extremity function serves mainly in providing balance in conjunction with the opposing side of the lower extremity. The movement of each leg is paired with the opposite arm which serves to counterbalance the body, particularly during the stance phase. The arms move most effectively (as seen in elite athletes) with the elbow joint at an approximately 90 degrees or less, the hands swinging from the hips up to mid chest level with the opposite leg, the Humerus moving from being parallel with the trunk to"

The long head of the biceps femoris extends the hip, as when beginning to walk; both short and long heads flex the knee and laterally (outwardly) rotate the lower leg when the knee is bent. The hamstrings play a crucial role in many daily activities such as walking, running, jumping, and controlling some movement in the trunk. In walking, they are most important as an antagonist to the quadriceps in the deceleration of knee extension."

After observing the struggles of the execution of activities involving the left and right arms and legs, led Joseph to believe that the two hemispheres possessed their own consciousness. Joseph also noted that the patient had other specific instances of conflict between the right and left hemispheres including, the left hand (right hemisphere) carrying out actions contrary to the left hemisphere's motives such as the left hand turning off the television immediately after the right hand turned it on. Joseph found that the patient's left leg would only allow the patient to"

The word ""ambidextrous"" is derived from the Latin roots ""ambi-"", meaning ""both"", and ""dexter"", meaning ""right"" or ""favorable"". Thus, ""ambidextrous"" is literally ""both right"" or ""both favorable"". The term ambidexter in English was originally used in a legal sense of jurors who accepted bribes from both parties for their verdict. Ambidexterity is highly prized in the sport of baseball. ""Switch hitting"" is the most common phenomenon, and is highly prized because a batter usually has a higher statistical chance of successfully hitting the baseball when it is thrown by an opposite-handed"

Joseph observed that one of the patient's right hemisphere is able to gather, comprehend, and express information. The right hemisphere was able to direct activity to the patient's left arm and leg. The execution of the left arm and leg's action as was inhibited by the left hemisphere. Joseph found that the patient's left leg would attempt to move forward as if to walk straight but the right leg would either refuse move"

From the straight position two pairs of movements of the hand are possible: abduction (movement towards the radius, so called radial deviation or abduction) of 15 degrees and adduction (movement towards the ulna, so called ulnar deviation or adduction) of 40 degrees when the arm is in strict supination and slightly greater in strict pronation. Flexion (tilting towards the palm, so called palmar flexion) and extension (tilting towards the back of the hand, so called dorsiflexion) is possible"

Another example is if someone was born with a neurological disorder such as major depressive disorder or had a stroke that resulted in a disorder, then they are capable of retrieving much of their lost function through practice, which in turn ""rewires"" the brain to mitigate neurological dysfunction. The idea of neural plasticity was first proposed during 1890 by William James in Principles of Psychology. During the first half of the 1900s, the word 'plasticity' was directly and indirectly rejected throughout science. Many scientists found it hard to receive"

""Adduction"" refers to a motion that pulls a structure or part ""toward"" the midline of the body, or towards the midline of a limb. In the case of fingers and toes, it refers to bringing the digits together, towards the centerline of the hand or foot. Adduction of the wrist is also called ""ulnar deviation"". Dropping the arms to the sides, and bringing the knees together, are examples of adduction. Ulnar deviation is"
"VI, and VII) components. In standard anatomical position (with the upper limb hanging alongside the body), the central components (II, III, and IV) lie lateral to the axis of abduction and therefore contribute to abduction from the start of the movement while the other components (I, V, VI, and VII) then act as adductors. During abduction most of these latter components (except VI and VII which always act as adductors) are displaced laterally and progressively start to abduct. From this extensive origin the fibers converge toward their insertion on the deltoid tuberosity on the middle of the lateral aspect of"
"ambidextrous handedness occurred at a higher rate in AGI respondents. According to Case and Ramachandan, these findings suggest that there is a biological basis of AGI bigenderism and hypothesized that it may correspond to an unusual degree of hemispheric switching, or when dominance switches from one hemisphere to the other during a single behavior, and callosal suppression of sex-appropriate body maps in the parietal cortex and its reciprocal connections with the insula and hypothalamus. They propose that ""coordination between shifts in brain connectivity, autonomic response, hormone release, and dynamic representation of body gender might together create the sense of gender"

Among some of the people with spastic diplegia who choose to be ambulatory on either an exclusive or predominant basis, one of the seemingly common lifestyle choices is for the person to ambulate within his or her home without an assistive device, and then to use the assistive device, if any, once outdoors. Others may use no assistive device in any ""indoor"" situation at all, while always using one when outdoors. Above the hips, persons with spastic diplegia typically retain normal or near-normal muscle tone and range of motion, though some lesser spasticity may also"

Allochiria is marked to have connections with a variety of senses and sometimes only certain kinds of stimuli can arouse the appropriate feeling of one sidedness. This is seen when there is a cross of electrical reflexes as a muscle is stimulated. Electromotor allochiria has been observed in the face, lower limbs, and upper limbs. In these cases, a stimulus presented on the affected side caused contraction of"
"Because the body is inverted during hand walking, blood pressure in the brain is greater than normal. As with other physical skills, one must practice hand walking in order to become proficient and develop adequate endurance. Handstands and hand walking are often learned at the same time because hand walking can be used to help maintain balance in a handstand before one learns to perform a stable handstand. Balance can also be maintained by varying the arch of the back. Some quadrupeds are able to walk bipedally on their forelimbs, thus performing ""hand"" walking in an anthropomorphic sense. For example,"

It also abducts the thigh, elevates the trunk and also prevents the trunk of a person from moving forward or backward when the rest of the body is in movement. The ""gluteal maximus"" also aids in stabilizing the femur and the tibia. The ""gluteas minimus"" and ""medius"" are also part of the gluteal muscles. If these muscles were missing, the leg would not be able to abduct or medial rotate the thigh. The body would also not be able to shift weight from one side to the other when one foot is"

The head becomes specialized with a mouth and sense organs, and the body becomes bilaterally symmetric for the purpose of movement, with symmetrical pairs of muscles and skeletal elements, though internal organs often remain asymmetric. Plants and sessile (attached) animals such as sea anemones often have radial or rotational symmetry, which suits them because food or threats may arrive from any direction. Fivefold symmetry is found in the echinoderms, the group that includes"

The open (the mouth, the anus, the vagina, etc.) and the penetrative (the nose, the penis, etc.) allow exchange between the body and the world (mostly through sex, eating, and drinking), but also to produce degrading material (curses, urine, feces, etc.). The lower stratum (belly, womb, etc.) is the place where renewal happens, where new life is forged, thus connecting degradation to renewal.
