Nervous System Part 2 Review

Front

What is Gray Matter?

Back

Gray Matter is a major component of the central nervous system, consisting of neuronal cell bodies, dendrites, and unmyelinated axons. It is involved in processing and interpreting information.

Front

What are Meninges?

Back

Meninges are the protective membranes that cover the brain and spinal cord, consisting of three layers: dura mater, arachnoid mater, and pia mater.

Front

What is the Dorsal Root?

Back

The Dorsal Root is a bundle of sensory nerve fibers that carry information from the body to the spinal cord, specifically transmitting sensory information.

Front

What is the Corpus Callosum?

Back

The Corpus Callosum is a thick band of nerve fibers that connects the left and right cerebral hemispheres, facilitating communication between them.

Front

What is the Pons?

Back

The Pons is a structure located in the brainstem that acts as a bridge between different parts of the nervous system, playing a key role in regulating sleep, respiration, and facial expressions.

Front

What is the Medulla Oblongata?

Back

The Medulla Oblongata is the lower part of the brainstem that controls vital autonomic functions such as heart rate, blood pressure, and breathing.

Front

What is the Ventral Root?

Back

The Ventral Root is a bundle of motor nerve fibers that carry signals from the spinal cord to the muscles, enabling movement.

Front

What is the Ventral Horn?

Back

The Ventral Horn is a region in the spinal cord that contains motor neurons responsible for sending signals to skeletal muscles.

Front

What is the Dorsal Horn?

Back

The Dorsal Horn is a region in the spinal cord that contains sensory neurons that receive and process sensory information from the body.

Front

What is the Central Canal?

Back

The Central Canal is a small channel in the center of the spinal cord that contains cerebrospinal fluid, which helps protect and nourish the spinal cord.
