Front

What is the anterior ramus of a spinal nerve?

Back

The anterior ramus is a branch of a spinal nerve that innervates the anterior and lateral parts of the trunk and limbs.

Front

What is the function of the posterior root of a spinal nerve?

Back

The posterior root contains sensory fibers that carry information from the body to the spinal cord.

Front

What is the function of the anterior root of a spinal nerve?

Back

The anterior root contains motor fibers that carry signals from the spinal cord to the muscles.

Front

What is the significance of the spinal nerve?

Back

Spinal nerves are crucial for transmitting sensory and motor information between the body and the central nervous system.
