Question

Brain is the main coordinating centre of the body. It is a part of the nervous system, which controls and monitors every organ of the body. Brain is divided into 3 parts: forebrain: has the cerebrum, thalamus and hypothalamus cerebrum (major part of the brain) is divided by a deep cleft into the left and right cerebral hemispheres.

Answer 1

Answer:

Explanation:The cerebrum is divided into two halves: the right and left hemispheres (Fig. 2) They are joined by a bundle of fibers called the corpus callosum that transmits messages from one side to the other. Each hemisphere controls the opposite side of the body. If a stroke occurs on the right side of the brain, your left arm or leg may be weak or paralyzed.

Not all functions of the hemispheres are shared. In general, the left hemisphere controls speech, comprehension, arithmetic, and writing. The right hemisphere controls creativity, spatial ability, artistic, and musical skills. The left hemisphere is dominant in hand use and language in about 92% of people.Left and right hemispheres
