MEDICAL PHYSIOLOGY

Detailed explanation-1: -The basic building block of the nervous system is a nerve cell, or neurone.

Detailed explanation-2: -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-3: -Neurons are specialized cells, found in the nervous system, which transmit information. Neurons contain a dendrite, a soma, and an axon. Some axons are covered with a fatty substance known as the myelin sheath, which surrounds the axon, acting as an insulator and allowing faster transmission of the electrical signal.

Detailed explanation-4: -Nervous tissue, present in both the CNS and PNS, contains two basic types of cells: neurons and glial cells.

Detailed explanation-5: -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.
