Cell is the smallest unit of life. All living organisms contains cells. And there are two cells in an organisms, the neuron and glial cells. In this topic, let us focus on understanding the function and parts of a neuron.
Neurons help transmit signals from the brain to different parts of the body in order to function and attend to the needs of each parts of the body. Neuron is composed of the cell body, dendrites, axon, and terminal buttons.
Now, let us learn its parts one by one. Starting off with the cell body or also known as soma contains the nucleus. The cell body connects to dendrites, which is responsible for receiving signals, and the axon is reponsible for transmitting information to other neurons. These informations are carried out as action potential, they travel down through the axon way faster due to the presence of myelin sheath. Lastly, the terminal buttons collects the information and sends them either in another neurons or in a muscle, directly
