Spinal Cord

Front

What is a spinal nerve?

Back

A spinal nerve is a mixed nerve that carries motor, sensory, and autonomic signals between the spinal cord and the body.

Front

What is the function of the denticulate ligament?

Back

The denticulate ligament is a fibrous structure that anchors the spinal cord to the dura mater, providing stability.

Front

What is white matter in the spinal cord?

Back

White matter consists of myelinated axons that form the ascending and descending pathways for communication between the brain and the body.

Front

What is the arachnoid mater?

Back

The arachnoid mater is the middle layer of the meninges that surrounds the brain and spinal cord, providing a protective barrier.

Front

What is the subarachnoid space?

Back

The subarachnoid space is the area between the arachnoid mater and the pia mater that contains cerebrospinal fluid (CSF), which cushions the spinal cord.

Front

What are the three layers of the meninges?

Back

The three layers of the meninges are the dura mater, arachnoid mater, and pia mater.

Front

What is the role of cerebrospinal fluid (CSF)?

Back

Cerebrospinal fluid (CSF) protects the brain and spinal cord by acting as a cushion, providing buoyancy, and removing waste.

Front

What is the function of the spinal cord?

Back

The spinal cord transmits signals between the brain and the rest of the body, and it also coordinates reflexes.

Front

What are spinal reflexes?

Back

Spinal reflexes are automatic responses to stimuli that occur without direct involvement of the brain, allowing for quick reactions.

Front

What is the difference between gray matter and white matter?

Back

Gray matter contains neuronal cell bodies, while white matter consists of myelinated axons.
