MEDICAL PHYSIOLOGY

Detailed explanation-1: -The basic unit of the nervous system is a nerve cell, or neuron. The human brain contains about 100 billion neurons. A neuron has a cell body, which includes the cell nucleus, and special extensions called axons (pronounced AK-sonz) and dendrites (pronounced DEN-drahytz).

Detailed explanation-2: -The neuron is the basic unit of the nervous system. Neurons make up the brain, spinal cord, and the peripheral nervous system by forming a network and communicating via synapses that receive and transmit information in the form of electrical or chemical signals in a rapid and precise manner.

Detailed explanation-3: -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.
