What are nerves?

Answer 1

Nerve cells, which are also called neurons, constitute the nerve. A nerve cell has a number of hair like dendrites, a cell body, cyton, and a long cable-like axon. A bundle of nerve cells constitute a nerve fibre.
Depending upon the function it is called sensory nerve, motor nerve.
Originating from, and forming a part of the kind of nervous system, a nerve may be called a cranial nerve, spinal nerve, sympathetic nerve, parasympathetic nerve.

Answer 2

A nerve is an enclosed, cable-like bundle of axons (the long, slender projection of a neuron). A nerve also includes the glial cells that ensheath the axons in myelin. Neurons are sometimes called nerve cells, though this term is technically imprecise since many neurons do not form nerves. Motor neurons, or nerves innervate or activate muscles groups to perform.

Answer 3

Nerves, or neurons, run throughout the human body, connecting everything together like a telephone network. The nerves in the central part of your body and brain form the central nervous system, whereas those in your arms and legs form the peripheral nervous system. The nerves act as a communication system, carrying information from one area of the body to another.

What do nerves do?

There are different types of nerves, and each has a special function in the communication system. For example, if you touch something hot, sensory neurons carry information up the spinal column to your brain. The brain then processes the information and sends it back down to your muscles via motor neurons. This information results in muscle contraction, i.e. removing your hand from the source of heat. All this happens in a matter of microseconds.
In the eye there are special nerves, called optic nerves, which take information that you receive in your eye to your brain

What Are Nerves

Answer 5

nerves are bundles of axon fibres( axon is the message carrying part of neuron or nerve cells).
there are 3 types of nerves - Sensory, Motor & Afferent .
Sensory -messages from sense organ /muscle/gland to Brain or Spinal Cord
Motor-messages from Brain or Spinal Cord to sense organ /muscle/gland
Afferent- contain both Sensory & Motor Axons( but each type works individually)

there are three kinds of nerve cells
sensory nerves
motor nerves and
mixed nerves

nerves are the structural and functional units of our nervous system. they carry stimuli to the brain and carry reflexes to effector organs. neuron is the longest known cell in the body.
