9 Cerebral Hemispheres The most superior and largest part of the brain. The entire surface of the cerebral hemispheres have elevated ridges of tissue called gyri,separated by shallow grooves called sulciFissures are the deeper grooves which separate large regions of the brain
11 The cerebral hemispheres are separated by a single deep fissure the longitudinal fissure Other fissures divide each cerebral hemispheres into number of lobesSomatic sensory area is located in the parietal lobe posterior to the central sulcusThe body represented upside-down mannerThe visual area is located in the in the posterior part of the occipital lobe
13 The auditory is located in the temporal lobe The olfactory area is found deep inside the temporal lobeThe primary motor area is anterior to the central sulcus in the frontal lobe.Broca’s area is found at the base of the precentral gyrusSpeech area is located at the junction of the temporal, parietal, and occipital lobes.
15 The cell bodies of neurons are found only in the outermost gray matter of cerebrum ,the cerebral cortexThe deeper cerebral white matter is composed of fiber tracts carrying impulses to or from the cortex.
21 The hypothalamus It makes the floor of the diencephalon It is an important autonomic nervous system centre (body temperature, water balance, and metabolism)The hypothalamus regulates the pituitary gland
38 Spinal cordIt extends from the foramen magnum of the skull to the 1st and 2nd lumbar vertebraThe spinal is protected by meninges which is extend well beyond the end of spinal cord.31pairs of spinal nervesCauda equinaCervical and lumbar enlargement
