The human brain's control of motor function is a mirror image in terms of connectivity; the left hemisphere controls the right hand and vice versa. This theoretically means that the hemisphere contralateral to the dominant hand tends to be more dominant than the ipsilateral hemisphere, however this is not always the case [ 2 ] and there are ...
Ambidexterity is the ability to use both the right and left hand equally well. [1] [2] When referring to objects, the term indicates that the object is equally suitable for right-handed and left-handed people.
A student writes with their left hand. In human biology, handedness is an individual's preferential use of one hand, known as the dominant hand, due to it being stronger, faster or more dextrous. The other hand, comparatively often the weaker, less dextrous or simply less subjectively preferred, is called the non-dominant hand.
The body behind the head compensates the asymmetric body orientation in the opposite direction, by turning to the right. (See schema.) Due to these oppositely directed compensations of the anterior head and the rest of the body, the animal becomes twisted. [10] The optic tract grows from the retina to the optic tectum.
Left-handed people can have problems with ordinary objects like scissors and rulers, which were designed for right-handed people. 19 ways the world is designed for right-handed people Skip to main ...
A stance with the left foot forward is called "regular" or "normal" stance. Jump and spin Direction of rotation in figure skating jumps and spins is not necessarily the same as the footedness or the handedness of each person. A skater can jump and spin counter-clockwise (the most common direction), yet be left-footed and left-handed. Ocular ...

In some cases the coordination of motor components is hard-wired, consisting of fixed neuromuscular pathways that are called reflexes. Reflexes are typically characterized as automatic and fixed motor responses, and they occur on a much faster time scale than what is possible for reactions that depend on perceptual processing. [27]
