PNS Learning Objectives:
After studying this material you should be able to:
1. List the components of the peripheral nervous system.
2. Classify a sensory receptor as simple or complex as well as by type of stimulus detected and location
3. Differentiate between somatic motor nerve endings and visceral motor nerve endings in terms of location, structure, and function.
4. Draw the anatomy of a nerve, including all pertinent structures, and relate this connective tissue arrangement to a previously studied system.
5. List the three major types of nerves in the body and the type of information that is transmitted by each.
6. Create a chart that organizes the 12 pairs of cranial nerves in terms of number and name, type of information transmitted, and body area innervated of each.
7. Discuss why all spinal nerves are referred to as mixed nerves.
8. Describe how the 31 pairs of spinal nerves are named.
9. Draw and label a cross section of the spinal cord and include ventral root, dorsal root, dorsal root ganglion, meningeal branch, dorsal ramus, and ventral ramus.
10. Compare and contrast the structures of the ventral root, dorsal root, and dorsal root ganglion as well as what the meningeal branch, dorsal ramus, and ventral ramus innervate.
11. Define reflex.
12. List the 5 components of a reflex arc, describe the function of each, and incorporate each of them into a pictoral representation of an arc.
