Nervous Tissue

Front

What is nervous tissue?

Back

Nervous tissue is a specialized tissue that makes up the brain, spinal cord, and nerves, responsible for transmitting signals throughout the body.

Front

What are the two main types of cells in nervous tissue?

Back

The two main types of cells in nervous tissue are neurons (nerve cells) and glial cells (supporting cells).

Front

What is the function of neurons?

Back

Neurons transmit electrical signals and communicate information throughout the body.

Front

What is the role of glial cells?

Back

Glial cells support, protect, and insulate neurons, and maintain homeostasis in the nervous system.

Front

What are oligodendrocytes?

Back

Oligodendrocytes are a type of glial cell in the CNS that insulate nerve fibers by forming myelin sheaths.

Front

What is myelin?

Back

Myelin is a fatty substance that surrounds and insulates nerve fibers, increasing the speed of electrical signal transmission.

Front

What is the central nervous system (CNS)?

Back

The CNS consists of the brain and spinal cord, and it processes and integrates information.

Front

What is the peripheral nervous system (PNS)?

Back

The PNS includes all the nerves outside the CNS, connecting the CNS to the rest of the body.

Front

What is the function of the motor division of the PNS?

Back

The motor division of the PNS conveys information away from the CNS to effectors such as muscles and glands.

Front

What is neuroglia?

Back

Neuroglia, also known as glial cells, are the supporting cells of the nervous system that provide structural and functional support to neurons.
