Axons:
A) transmit nerve impulses to terminal buttons and vary in length
B) are always bundled with other axons to form nerves and are individually very short in length
C) vary in length depending on whether they send or receive information
D) are uniform in size throughout the body though capable of serving different functions

Question

Quizplus · Accepted Answer

Axons transmit nerve impulses away from the cell body to terminal buttons or other neurons. They can vary in length depending on their location and function, and can be very long in some cases (such as the axons of motor neurons that extend from the spinal cord to the foot). Additionally, the length of an axon is proportional to the speed at which it conducts nerve impulses. However, axons are not always bundled with other axons to form nerves - this is only true in certain parts of the nervous system, such as the peripheral nervous system. Axons also vary in their size and shape depending on their function and location in the body.
