Explanation: 

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: -Neuron is an individual specialized cell which are primarily involved in transmitting information through electrical and chemical signals. 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.

Detailed explanation-3: -Neurons are the structural and functional units of the nervous system. They consist of a cell body, dendrites, and axon. Neurons transmit nerve impulses to other cells. Types of neurons include sensory neurons, motor neurons, and interneurons.

Detailed explanation-4: -Nerve cells (neurones) are ‘excitable’ cells which can transduce a variety of stimuli into electrical signals, continuously sending information about the external and internal environment (in the form of sequences of action potentials) to the central nervous system (CNS).

Detailed explanation-5: -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.
