Spinal Cord

Front

What is the function of the lateral horns in the spinal cord?

Back

The lateral horns contain neurons that are involved in the autonomic nervous system, specifically in the sympathetic division.

Front

What are dorsal roots?

Back

Dorsal roots are the sensory nerve fibers that carry information from the body to the spinal cord.

Front

What is the posterior median sulcus?

Back

The posterior median sulcus is a groove that runs along the back of the spinal cord, separating the two halves of the gray matter.

Front

What are ventral roots?

Back

Ventral roots are the motor nerve fibers that carry signals from the spinal cord to the muscles.

Front

What is the central canal of the spinal cord?

Back

The central canal is a small, fluid-filled space in the center of the spinal cord that contains cerebrospinal fluid.

Front

What is the role of the gray matter in the spinal cord?

Back

Gray matter contains neuronal cell bodies and is involved in processing information and reflexes.

Front

What is the difference between the dorsal horn and the ventral horn?

Back

The dorsal horn contains sensory neurons, while the ventral horn contains motor neurons.

Front

What is the significance of the anterior median fissure?

Back

The anterior median fissure is a deep groove that separates the two halves of the spinal cord and is important for structural organization.

Front

What types of neurons are found in the dorsal roots?

Back

Dorsal roots contain sensory neurons that transmit sensory information to the spinal cord.

Front

What is the composition of the spinal cord's white matter?

Back

White matter is composed of myelinated axons that facilitate communication between different parts of the nervous system.
