Unit 11 Day 2 Nervous Tissue: Structure and Function

Include your name, hour, date and class in your document.

1. Histological examination of a slice of neural tissue reveals a bundle of nerve fibers held together by cells whose multiple processes wrap around several fibers and form a myelin sheath. The specimen is likely to be:

A. a nucleus

B. a ganglion

C. a nerve

D. a tract

 

2. Briefly explain how nerve impulses are initiated and transmitted and why one-way conduction at synapses always happens.

3. Name four types of cutaneous sensory receptors. Which of the of these receptors types is most numerous? Why?

4. What is a reflex arc? Name its minimum components .
