1. Nervous System Review

3. Cerebellum
The cerebellum is the structure of the brain responsible for coordination of movement, muscle coordination, muscle tone, and balance.

4. Cerebrum
The cerebrum is the largest, most anterior part of the brain. It is divided into right and left halves, called hemispheres.

5. Medulla Oblongata
The medulla oblongata is an enlarged continuation of the spinal cord extending up into the pons.

6. Meninges
The organs of the central nervous system (brain and spinal cord) are covered by 3 connective tissue layers collectively called the meninges. Consisting of the pia mater (closest to the CNS structures), the arachnoid and the dura mater (farthest from the CNS),

7. Midbrain
The midbrain is located beneath the cerebrum in the uppermost region of the brainstem.

8. Pons
The pons appears as a rounded bulge on the underside of the brain stem and separates the midbrain from the enlarged continuation of the spinal cord.

9. Spinal Cord
The spinal cord is a column of nervous tissue from the brainstem through the vertebrae, responsible for nerve conduction to and from the brain and the body.

10. Ventricles
Ventricles are a series of interconnected cavities within the cerebral hemispheres and brainstem filled with cerebrospinal fluid.

11. Gyri and Sulci
Convolutions (mounds) of the cerebral hemispheres are called gyri (singular gyrus).
Shallow grooves that separate gyri are called sulci (singular sulcus).

13. Parts of the Neuron

14. Central Nervous System
The central nervous system is made of up the brain and spinal cord.

15. Peripheral Nervous System
The peripheral nervous system is made up of the 12 pairs of cranial nerves and 31 pairs of spinal nerves.
