Nerve Tissue

Nerve tissue is a type of tissue that is found in the nervous system and is made up of specialized cells called neurons. Neurons are the building blocks of the nervous system and are responsible for transmitting electrical signals throughout the body. Nerve tissue also contains support cells called neuroglia, which provide structural support and insulation for the neurons.

Structure of Nerve Tissue

Nerve tissue is composed of neurons, which have a cell body, dendrites, and an axon. The cell body contains the nucleus and other organelles, and the dendrites are the short, branched extensions that receive signals from other neurons. The axon is a long, slender projection that carries signals away from the cell body to other neurons or to muscles and glands.

Function of Nerve Tissue

The primary function of nerve tissue is to transmit electrical signals, known as nerve impulses, throughout the body. These impulses allow for communication between different parts of the body and are essential for processes such as sensation, movement, and coordination.
