Exercise 17: Histology of Nervous Tissue
What two types of cells make up nervous tissue? What are the parts of a neuron? Which parts receive information, and which send it? How many dendrites can a neuron have? How many axons? What is meant by the term "nerve fiber"? What cells provide the myelin sheath for peripheral neurons? For those in the central nervous sytsem? Be able to identify on diagrams and slides where possible, the neuron cell body, nucleus, nucleous, Nissl bodies, Schwann cells, node of Ravier, axon, and dendrites. Be able to identify diagrams of unipolar, bipolar and multipolar neurons. What is a sensory or afferent neuron? What is a motor, or efferent neuron? What is an association, or interneuron?  What is a mixed nerve? Be able to describe the structure of a peripheral nerve, and identify the epineurium, perineurium, and endoneurium.



Exercise 21: Spinal Cord, Spinal Nerves, and the Autonomic Nervous System
Spinal cord:
In diagrams and on models and slides where possible, be able to identify the following parts of the spinal cord: conus medullaris, filum terminale, denticulate ligaments, cauda equina, gray matter ( posterior or dorsal horns; anterior or ventral horns; lateral horns; gray commissure) central canal, dorsal root, dorsal root ganglion, ventral root, spinal nerves, white matter, anterior median fissure, posterior median sulcus, posterior median septum, posterior funiculus, lateral funiculus, anterior funiculus. What is a tract?
 

Autonomic Nervous System:  What is the autonomic nervous system? How does it differ from the somatic nervous system?
How do the sympathetic and parasympathetic nervous systems differ on: the origin of their nerves, the location of their ganglia (what effect does this have on the range of their effects?), their effects on the eye, salivary glands, stomach, heart, and bronchioles?  What neurotransmitters are released by their preganglionic fibers? By the postganglionic fibers?
