What is the nerve cell known as?

• A. Glial cell
• B. Axon
• C. Dendrite
• D. Neuron

Answer: (D)

The nerve cell is called a neuron. Neurons are the basic units of the nervous system that process and transmit information. They receive signals through dendrites, integrate them in the cell body, and send impulses along the axon to other neurons or effectors. Glial cells provide support and maintenance but are not nerve cells themselves, while the axon and dendrites are parts of a neuron, not the whole cell.
