Question

Explain about the parts of the brain

points ➡ 25

Answer 1

a that part of the central nervous system contained within the skull the brain weight c. 1.4 kg
the surface of the cerebral hemisphere is wrinkled or furrowed .These hemisphere are divided into the frontal , temporal,parental,and occipital lobes,and the frontal lobes are separated from the partietal lobes by the fissure of Rinaldo,which divides the brain into the effecr or are in front- the part which is concerned with action , and the receptor area behind- the part which is concerned with receiving stimuli .The outer parts of all the convolution s are made of grey matter which consists of innumerable nerves cells .The remainder of the cerebrum is formed of white matter,made up of nerves fibers. These conduct impulses from the end organs allover the body to the cortex.They cross from one side to the other in the pyramid of the medulla, a fact which explains why each side of the brain governs the opposite side of the body,
The brain is enclosed by 3 membranes , which separate it from the skull.The cerebro - spinal fluid surrounds the whole of the brain,spinalcord,and nerves , in a thin layer to form a kind of water- cushion in which the nerve tissues float
