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 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: -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-4: -The human nervous system is made up of three basic parts: the central nervous system, the peripheral nervous system, and the autonomic nervous system. Without a doubt, it is the most complex part of the human body, a masterpiece of nature.
Detailed explanation-5: -Based on their roles, the neurons found in the human nervous system can be divided into three classes: sensory neurons, motor neurons, and interneurons.
