ANATOMY

Detailed explanation-1: -Neurons (also called neurones or nerve cells) are the fundamental units of the brain and nervous system, the cells responsible for receiving sensory input from the external world, for sending motor commands to our muscles, and for transforming and relaying the electrical signals at every step in between.

Detailed explanation-2: -The smallest functional unit of the nervous system is known as a neuron. A neuron is a specialized cell which transmits impulses. Its main function is to process and transmit information in the form of chemical or electrical signals. Neurons are the basic cells that make up the entire nervous system.

Detailed explanation-3: -Neurons are information messengers. They use electrical impulses and chemical signals to transmit information between different areas of the brain, and between the brain and the rest of the nervous system.

Detailed explanation-4: -First, the basic functions of the nervous system are sensation, integration, and response. Secondly, control of the body can be somatic or autonomic-divisions that are largely defined by the structures that are involved in the response.

Detailed explanation-5: -The neuron is the structural and functional unit of the nervous system. Neurons are capable of detecting, receiving, and transmitting a variety of inputs. The three major parts of this microscopic structure are the cell body (soma), dendrites, and axons.
