Question

What is the longest cell in the human body?

Answer 1

Hint:There are different sizes and shape of the cells. They are the active component of the nervous system that communicates with each other through the electrical signals. They ensure the effective transmission of the information.

Complete answer:
>Nerve cells or neurons are the longest cell in the human body. It is the basic unit of the nervous system that performs important functions.
>Nerve is a specialized cell of the nervous tissue that communicates with each other through electrical signals.
>These cells help in proper functioning of the brain and coordination of the body parts. There are three types of neurons or nerve cells. i.e., interneurons, sensory neurons, motor neurons.
>Interneurons help in connecting one neuron to the other neuron. Sensory neurons provide the stimuli response and activate five senses in the body. i.e., feel, smell, sight, hear and sound. Motor neurons receive the signals.
>Nerve cells or neurons consist of dendrites, axon and soma. These cells transmit information with the help of these three components. Soma contains the nucleus in the nerve cell. Dendrites receive electrical signals from the axon and transmit it to the other organs.
>There are about $10^20$ individual neurons in the nervous system of a human being.

Note:Nerve cell is the longest cell of the human body that helps in maintaining balance and coordination of the different body parts. Nerve cells are the specialized cells of the nervous tissue that transmit information with the help of 3 components like axon, soma and dendrites.
