MEDICAL PHYSIOLOGY

Detailed explanation-1: -(nerv sel) A type of cell that receives and sends messages from the body to the brain and back to the body. The messages are sent by a weak electrical current. Also called neuron.

Detailed explanation-2: -The cells in nervous tissue that generate and conduct impulses are called neurons or nerve cells. These cells have three principal parts: the dendrites, the cell body, and one axon.

Detailed explanation-3: -They are found in the brain, spinal cord and the peripheral nerves. Neuron is also known as the nerve cell. There are two types of neurons – sensory neurons and motor neurons. A group of neurons form a nerve.

Detailed explanation-4: -Neurons are specialized to transmit information throughout the body. Whereas nerve is a whitish fibre or bundle of fibres in the body made up of number of neuron cells that transmits impulses of sensation to the brain or spinal cord, and impulses from these to the muscles and organs.

Detailed explanation-5: -axon, also called nerve fibre, portion of a nerve cell (neuron) that carries nerve impulses away from the cell body. A neuron typically has one axon that connects it with other neurons or with muscle or gland cells. Some axons may be quite long, reaching, for example, from the spinal cord down to a toe.
