2.Name the glial cells of the CNS and their function:

3.What’s the glial cell in the PNS that is the same as oligodendrocytes?

4. What are the basic steps that occur in transmission in a synapse?

5.Sensory is the same as ______, motor is the same as ______and interneuron is the same as ______fibers______. Sensory neurons transmit impulses from/to sensory receptors from/to CNS. Motor neurons transmits impulses from/to CNS from/to skeletal muscles and glands.

6.Association fibers make up ______% of neurons in the body

7.Describe how regeneration of nervous tissue occurs in the CNS and the PNS

8.Where is CSF found/around what meninges and how is it formed and circulated?

11. What sense in humans is not relayed through the thalamus?

12. True or False:

Each muscle receives a nerve supply from more than one spinal nerve, so damage to one spinal nerve doesn’t completely paralyze a muscle.
