ANATOMY

Detailed explanation-1: -Cells of the nervous system, called nerve cells or neurons, are specialized to carry “messages” through an electrochemical process. The human brain has approximately 86 billion neurons. To learn how neurons carry messages, read about the action potential.

Detailed explanation-2: -The basic unit of communication in the nervous system is the nerve cell (neuron). Each nerve cell consists of the cell body, which includes the nucleus, a major branching fiber (axon) and numerous smaller branching fibers (dendrites).

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.

Detailed explanation-4: -Though nerve and neuron sounds similar but they are two different components of the body and are closely related to each other. Nerves are actual projections of neurons. Neuron is an individual specialized cell which are primarily involved in transmitting information through electrical and chemical signals.

Detailed explanation-5: -Motor neurons have the most common type of ‘body plan’ for a nerve cell-they are multipolar, each with one axon and several dendrites.
