Question

The collection of axons that carries information between the central nervous system and the peripheral effectors is called the

A) axon hillock.
B) varicosity.
C) axon.
D) dendrite.
E) nerve.

Answer 1

The correct term for a bundle of axons in the peripheral nervous system is a nerve. These structures transmit sensory and motor information, and distinguish from similar CNS structures called tracts.

Step-by-step explanation:

The collection of axons that carries information between the central nervous system (CNS) and the peripheral effectors is called a nerve. In the peripheral nervous system (PNS), a bundle of axons is specifically referred to as a nerve. In contrast, a similar structure in the CNS is known as a tract. Axons are the long, thin extensions of the cell body that transmit nerve impulses away from the cell body. These myelinated fibers form nerves in the PNS, which help in transmitting sensory and motor signals throughout the body.

Each spinal nerve consists of sensory and motor axons that facilitate communication between the spinal cord and various parts of the body. Moreover, the impulses transmitted along axons can synapse with other neurons, muscles, or glands. Hence, the correct answer to the question, 'Which term describes a bundle of axons in the peripheral nervous system?' is d. nerve.
