Document Summary

Central nervous system consists of the brain and spinal cord. Peripheral nervous system consists of nerves outside the brain and spinal cord. Cell body: also known as soma, contains cell nucleus. It"s the first part to receive nervous impulses. Synapse: space through which a nervous impulse travels between nerve cell. Nerve: bundles of dendrites and axons that travel together like strands of rope. Afferent cells: carry messages towards the cns (brain and spinal cord). Efferent nerve: carry messages away from the cns (brain and spinal cord). Ganglion: large network of nerves in the peripheral nervous system. Cerebell/o: cerebellum cerebr/o: cerebrum (posterior part of the brain that coordinates muscle movements and maintains balance) Pont/o: pons (bridge connecting various parts of the brain. Anterior to the cerebellum and between the medulla and the rest of the midbrain) Dur/o: dura mater (outermost)- very think and tough.
