Cranial nerves, which connect the brain to sensory organs and muscles of the head, can only be seen from the ventral surface of the brain. The names, locations, and functions of the cranial nerves are as shown in, Fig. 1.9, 1.11, and Tab 1.1. 1.10 A shows the midsagittal section of the brain, which reveals all of the major subdivisions. A roughly horizontal sulcus, the cingulate sulcus, extends across the middle of the brain. The prominent gyrus below it, the cingulate gyrus, along with the cortex adjacent to it, is known as the limbic lobe.
Limbic system is concerned with emotions, feelings, etc.
Fig 1.10 C shows an enlarged view of the diencephalon. The dorsal thalamus, the largest component of the diencephalon, is involved in relaying information to the cerebral cortex from other parts of the brain. The pituitary gland is the master endocrine gland. Optic chiasm is formed by crossing of the optic nerves from the eyes. 1.11 shows the midbrain.
