Question

1. cells that nourish neurons, remove wastes, and defend neurons against infections are called

a. glial cells
b. parasympathetic cells
c. cell bodies
d. sympathetic cells

1. the basic structures of the general impulse transmission pathway and a reflex arc are

a. sensory receptors and sensory neurons
b. interneurons (associative neurons)
c. motor neurons and effectors (muscles)
d. all the above
hint: compare figure 11.6 with figure 11.8.

Explanation:

For question 5, glial cells support neurons by nourishing them, removing waste, and providing defense against infections. Parasympathetic and sympathetic cells are related to the autonomic - nervous - system's functions rather than neuron - support. Cell bodies are part of neurons themselves. For question 6, the general impulse transmission pathway and reflex arc include sensory receptors and neurons that detect stimuli, interneurons that process information, and motor neurons and effectors that produce a response.

Answer:

1. A. glial cells
2. D. all the above
