Structure and Functions of Neuron | Notes

Neurons are the basic building blocks of our nervous system and are responsible for transmitting information throughout the body. Here’s a simple explanation of their structure and functions:

Structure of a Neuron:

  • Cell Body (Soma): Cell Body or Soma is the main part of the neuron that contains the nucleus. The nucleus controls the cell’s activities and contains the genetic material (DNA).
  • Dendrites: Dendrites are branch-like structures that receive signals from other neurons. They carry the information towards the cell body.
  • Axon: Axon is a long, thin structure that carries signals away from the cell body to other neurons, muscles, or glands. The axon is sometimes covered with a fatty layer called the myelin sheath, which helps speed up the transmission of signals.
  • Axon Terminals: Axon Terminals are the ends of the axon that connect to other neurons. They release chemicals called neurotransmitters that carry the signal to the next neuron.

Functions of Neuron:

  • Receiving Information: Neurons receive information from other neurons through their dendrites.
  • Processing Information: The cell body processes this information and determines if it should send a signal to the next neuron.
  • Transmitting Information: If the signal is strong enough, it travels down the axon to the axon terminals, where it is passed on to the next neuron or to a muscle or gland.

Synapse:

The small gap between the axon terminals of one neuron and the dendrites of another is called a Synapse. Neurotransmitters cross this gap to transmit the signal to the next neuron.

In summary, neurons are specialized cells that communicate with each other to control everything we do, from thinking to moving. Their structure is perfectly designed to receive, process, and transmit information efficiently throughout the nervous system.
