Name the longest cell in the human body.
The longest cells in the human body are neurons.
Neurons or the nerve cells form the basic components of the nervous system. A typical neuron possesses a cell body called as soma, hair like structures called as dendrites and an axon. Neurons are specialized in transmitting information throughout the body. Three types of neurons are sensory neurons, motor neurons and interneurons. Neurons possess a membrane that is designed to send information to other cells. Neurons synthesise chemicals called as neurotransmitters which help in transmission of information.
