A neuron is a specialized cell in the nervous system that is responsible for transmitting information through electrical and chemical signals. Neurons have three main parts: the cell body, dendrites, and axon.
1. Cell body (soma): The cell body contains the nucleus and other organelles that are necessary for the neuron to function. It also processes incoming signals from other neurons.
2. Dendrites: Dendrites are branch-like structures that extend from the cell body and receive signals from other neurons. They act as the input region of the neuron.
3. Axon: The axon is a long, slender projection that carries signals away from the cell body to other neurons or muscles. It is the output region of the neuron.
4. Myelin sheath: The axon is often surrounded by a myelin sheath, which is a fatty substance that helps to insulate the axon and speed up the transmission of signals.
5. Axon terminals: At the end of the axon are small structures called axon terminals, which release neurotransmitters that transmit signals to other neurons or muscles.
Overall, neurons function by receiving signals through their dendrites, processing these signals in the cell body, and transmitting them along the axon to other neurons or muscles. This process allows for the rapid communication and coordination of activities within the nervous system.

Diagram of a Neuron:

Functions of a Neuron:
1. Dendrites: Receive signals from other neurons or sensory receptors.
2. Cell Body (Soma): Contains the nucleus and other organelles that control cell function.
3. Axon: A long, slender projection that transmits signals away from the cell body.
4. Axon Terminal: The end of the axon, where signals are transmitted to other neurons or muscles/glands.
5. Myelin Sheath: Insulating layer around the axon that speeds up signal transmission in myelinated neurons.
Key Functions:
- Reception: Receiving signals from other neurons or sensory receptors.
- Integration: Combining multiple signals and determining the overall response.
- Transmission: Sending signals to other neurons or muscles/glands.
Types of Neurons:
- Sensory Neurons: Transmit signals from the body's sensory receptors to the central nervous system.
- Motor Neurons: Transmit signals from the central nervous system to muscles or glands, causing them to contract or secrete hormones.
- Interneurons: Connect sensory and motor neurons within the central nervous system, enabling complex information processing.
