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?
