An experiment looking at an isolated neuron revealed a sensory nerve with one process contain-ing a dendritic portion extending away from the CNS and an axon extending toward the CNS.
 
  Which of the following classifications would this neuron fall into?
  a. Bipolar
  b. Multipolar
  c. Pseudounipolar
  d. Interpolar

Question 2

A nurse is preparing to teach about nerves. Which information should the nurse include? The ax-on leaves the cell body at the:
 
  a. axon hillock.
  b. Nissl body.
  c. node of Ranvier.
  d. myelin sheath.

Answer to Question 1

ANS: C
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 have two dis-tinct processes arising from the cell body. Multipolar neurons are the most common and have multiple processes capable of extensive branching. A motor neuron is typically multipolar. Inter-polar is not a type of neuron.

Answer to Question 2

ANS: A
The axon hillock is the cone-shaped process where the axon leaves the cell body. The Nissl body is involved in protein synthesis. Axons branch at the node of Ranvier. The myelin sheath covers the entire membrane.
