The ventral part contains longitudinal fibers primarily from the corticospinal, corticobulbar, and corticopontine tracts. The principal regions of the midbrain are the tectum, the cerebral aqueduct, tegmentum, and the cerebral peduncles. Rostrally the midbrain adjoins the diencephalon (thalamus, hypothalamus, etc.), while caudally it adjoins the hindbrain (pons, medulla and cerebellum). In the rostral direction, the midbrain noticeably splays laterally. Sectioning of the midbrain is usually performed axially, at Place the brain with the cerebrum facing up.

Use a scalpel (or sharp, thin knife) to slice through the brain along the center line, starting at the cerebrum and going down through the cerebellum, spinal cord, medulla, and pons. Sheep Brain Dissection Guide Gyrus Sulcus 2. Next locate the area referred to as the brain stem. This area is made up of the pons, medulla, and cerebellum. Find also the root where the pituitary gland was attached to your brain. The pituitary gland may have been there when you first cleaned your brain. Pons Medulla Pituitary Gland Cerebellum The Pons Is Vital to Experiencing Some Sensory Input.

Gyrus - a ridge or fold between two clefts on the cerebral surface in the brain. Sulcus - a groove or furrow, especially one on the surface of the brain. Pons -Connects the cerebellum to the nervous system. Medulla -Helps maintain blood pressure and heart rate normal.

Set the brain down so the flatter side, with the white spinal cord at one end, rests on the dissection pan . Notice that the brain has two halves, or hemispheres. Can you tell the difference between the cerebrum
