The nervous system is composed of or nerve cells. a. receptors b. neurons c. neurotransmitters d. axons

B) Neurons.

Nervous system comprises of two branches - CNS ( Central Nervous System) and PNS (  Peripheral Nervous System). It receives and transmits signals in different parts of the body. Neurons or nerve cells are the basic functional unit of the nervous system. The function of neurons is to transmit the signals by generating action potential.

A typical neuron consists of - Cell body, axon, and dendrites.

Cell body receives signals through dendrites, axon transmits it in the nerve endings. Finally the signals are transmitted to next neuron via signaling molecules called as neurotransmitters. The junction between adjacent neurons is called as neurotransmitter junction or synapse.

The nervous system is composed of (answer B  ) Neurons.

How?:

The neuron is the basic unit in the nervous system. Neurons make up both parts of the Central and Peripheral Nervous systems. It is a specialized conductor cell that receives and transmits electrochemical nerve impulses. A typical neuron has a cell body and long arms that conduct impulses from one body part to another body part.
