Exam 16: Nervous Tissue

A neuron having one axon and one dendrite, such as those located in the retina or inner ear, are classified as _____ neurons.

Neurons that originate in the central nervous system and that function to carry information to smooth, skeletal, or cardiac muscle are efferent (motor) neurons.

For a typical (multipolar) neuron, use correct anatomical terms to describe the structure of an axon from the point where it is attached to the neuron cell body to where it ends at a synapse.
