Document Summary

Neuroglia support and maintain neurons by segregating and insulating them. The cns is made up of the spinal cord and brain. Cns neuroglia include astrocytes, microglial cells, ependymal cells, and oligodendrocytes. A collection of cell bodies is call a nucleus. A bundle of nerve fibers is called a tract. The pns is made up of the cranial and spinal nerves. The pns is split up into the sensory (afferent) and motor (efferent) divisions. Cns and the motor division carries messages from the cns. The efferent (motor) division is further split up into the somatic system (voluntary; skeletal muscles) and the autonomic system (involuntary; smooth and cardiac muscle, and glands) Pns neuroglia include schwann cells and satellite cells. A collection of cell bodies is called a ganglion. A bundle of nerve fibers is called a nerve. Describe the major classes and functions of neurotransmitters. The measure of potential energy of separated electrical charges is called voltage (v)
