Correct option is C
The correct answer is:(C) nerve cell.
- A nerve cell, also known as a neuron, is the basic functional unit of the nervous system. Neurons are specialized to transmit electrical signals throughout the body, enabling communication between the brain, spinal cord, and other body parts.
The structure of a nerve cell (neuron):
- Cell Body (Soma): Contains the nucleus and organelles, responsible for the cell's metabolic functions.
- Dendrites: Branch-like structures that receive signals from other neurons and transmit them to the cell body.
- Axon: A long, slender fiber that carries electrical impulses away from the cell body to other neurons or target cells.
- Myelin Sheath: A fatty layer that insulates the axon, speeding up the transmission of electrical signals.
- Axon Terminals: The endings of the axon that release neurotransmitters to pass signals across synapses (gaps between neurons).
