Nervous Tissue

Without nervous tissue, almost all functions in your body would not occur. The nervous system is responsible for sending electrical signals throughout the body. These tissues are responsible for conscious and unconscious actions like moving an arm and constriction of your blood vessels.

The cells of nervous tissue, also known as neural cells, can be classified into two categories:

  1. Neurons
  2. Neuroglia

These cells are some of the longest cells in your entire body but are incapable of cell reproduction. Thus, damage or death of these cells can lead to permanent damage in your body. These cells also consist of unique anatomy. These cells have a Soma or cell body, Axon or nerve fiber, and dendrites or signal receiver sites.

Neurons are the main cells in the nervous system. They are responsible for transmitting the impulse in this system. They will release chemical and electrical signals that lead to reactions or systems to process something.

Neuroglia are the cells that support the neurons. They do this by wrapping the neurons with myelin. This myelin helps increase the speed at which neurons transmit their signals.
