PATHOLOGY

Detailed explanation-1: -The brain is divided into symmetrical left and right hemispheres. Each hemisphere is in charge of the opposite side of the body, so your right brain controls your left hand. The right hemisphere also takes in sensory input from your left side and vice versa. The brain is segmented into regions called lobes.

Detailed explanation-2: -The human brain is basically symmetrical, split down the middle: the right cerebral hemisphere receives sensory input from and directs movement on the left side of the body, while the left hemisphere governs corresponding functions for the right side. Symmetry only goes so far, however-there are differences, too.

Detailed explanation-3: -The right hemisphere controls the left side of the body, and the left half controls the right side of the body. The two halves communicate with one another through a large, C-shaped structure of white matter and nerve pathways called the corpus callosum. The corpus callosum is in the center of the cerebrum.

Detailed explanation-4: -The right side of the brain controls the left side of the body. This means that their movement will be worse on the left side.
