SDSU BIO 212 Test 4 Questions and Answers
100% Solved
Anaxonic Neurons Neuron that has multiple protoplasmic extensions coming off all
regions of the cells, star shaped, unknown function and located only in the brain
Multipolar Neurons Neuron with a single protoplasmic extension called an axon coming
directly off the cell body, mostly interneurons and are motor (efferent) neurons. Most common
Bipolar Neurons Neuron with two protoplasmic extensions, one acting like a dendrite and
one acting as an axon coming directly off two opposite regions of the body, carry sensory
(afferent) impulses, and located in special senses organs
Pseduounipolar Neuron Neuron whose cell body is off to one side of a continuous
protoplasmic extension that acts as the dendrite and axon, and are sensory (afferent) neurons
