Question

_____ are to the central nervous system as _____ are to the peripheral nervous system. A. Neurons; nerves B. Axons; dendrites C. Myelin sheaths; neurotransmitters D. Neurotransmitters; hormones

Answer 1

The answer is A. Neurons are corresponding elements of the central nervous system as nerves are to the peripheral nervous system.

Step-by-step explanation:

Neurons are to the central nervous system (CNS) as nerves are to the peripheral nervous system (PNS). Therefore, the correct answer to the question is A. Neurons; nerves. The CNS includes the brain and spinal cord while the PNS consists of nerve fibers that extend from the CNS to all parts of the body. Neurons are individual nerve cells which form the basic building blocks of the nervous system, whereas nerves are bundles of axons in the PNS that act as information highways to carry signals between the brain and spinal cord and the rest of the body.

Answer 2

A. Neurons; nerves

Step-by-step explanation:

The nervous system is comprised of two types of a system called the peripheral and the central nervous system.

A neuron is the functional unit of the nervous system which transmits the signals to the organs and to the brain.

The central system is composed of the neurons of the spinal cord and the brain whereas the peripheral system is composed of the neurons which connect the central nervous system to the organs, therefore, the neurons of the peripheral system are the considered the extensions of the central nervous system and thus are called nerves composed of axons of the neurons.

Thus, Option-A is the correct answer.
