Nerve Tissue

Nerve tissue is a specialized type of tissue found in the nervous system, which includes the brain, spinal cord, and nerves. It is made up of two main types of cells: neurons and neuroglia (also known as glial cells).

Neurons

Neurons are the primary cells of the nervous system and are responsible for transmitting electrical and chemical signals. They have a cell body, dendrites, and an axon. The cell body contains the nucleus and other organelles, while the dendrites receive signals from other neurons. The axon is a long, thin projection that transmits signals to other neurons or to muscles or glands.

Neuroglia

Neuroglia are support cells that provide structural support and insulation for the neurons. They also play a role in the immune system of the nervous system and help regulate the chemical environment around neurons.

Functions of Nerve Tissue

Nerve tissue is responsible for transmitting and processing sensory information, controlling motor functions, and regulating bodily functions. It plays a crucial role in communication within the body and with the external environment.

Study Guide

1. Describe the structure of a neuron and its functions.
2. Explain the role of neuroglia in nerve tissue.
3. Discuss the main functions of nerve tissue in the body.
4. Compare and contrast the central nervous system and the peripheral nervous system.
5. Describe the process of nerve impulse transmission.

Understanding nerve tissue is essential for comprehending the complexities of the nervous system and its functions in the human body.
