Answer to Question 1

ANS: A
Large axons transmit impulses at a faster rate than cell bodies. The axon hillock has a low thresh-old level. The dendrites carry impulses toward the cell body, but not as quickly as large axons.

Answer to Question 2

ANS: D
A motor neuron is typically multipolar. Unipolar neurons are found in the retina. Pseudounipolar neurons have one process; the dendritic portion of each of these neurons extends away from the CNS, and the axon portion projects into the CNS. Bipolar neurons are found in the eye.
