Nervous Tissue

Nervous tissue is a type of tissue that makes up the nervous system, which includes the brain, spinal cord, and nerves. It is responsible for receiving and transmitting electrical signals that allow the body to respond to its environment.

Structure of Nervous Tissue

Nervous tissue is made up of two main types of cells: neurons and neuroglia.

• Neurons: Neurons are the primary cells of the nervous system. They are responsible for transmitting electrical signals. Neurons have a cell body, dendrites (which receive signals), and an axon (which transmits signals).
• Neuroglia: Neuroglia, also known as glial cells, are support cells that provide physical support, insulation, and nutrients to neurons.

Function of Nervous Tissue

The main function of nervous tissue is to transmit electrical signals throughout the body. This allows for the coordination of movement, regulation of bodily functions, and processing of sensory information.
