Nervous Tissue

Nervous tissue is a 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.

Neurons

Neurons are the primary cells of the nervous system. They are responsible for transmitting electrical and chemical signals throughout the body. Neurons 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 carries signals away from the cell body to other neurons, muscles, or glands.

Neuroglia

Neuroglia, also known as glial cells, are support cells that provide structure and protection for neurons. They also play a role in insulating and nourishing neurons. There are several types of neuroglia, each with unique functions, such as Schwann cells, oligodendrocytes, astrocytes, and microglia.

Functions of Nervous Tissue

Nervous tissue is responsible for coordinating and controlling many bodily functions. It allows for the communication and integration of sensory information, motor responses, and higher cognitive processes such as thinking, learning, and memory.
