What is the medical term for record of the spinal cord?

What is the medical term for record of the spinal cord?

Myelography: The diagnostic study of the spinal cord after injecting a contrast medium. The resulting record is called a myelogram.

What is spinal cord short note?

A column of nerve tissue that runs from the base of the skull down the center of the back. It is covered by three thin layers of protective tissue called membranes. The spinal cord and membranes are surrounded by the vertebrae (back bones). The spinal cord and the brain make up the central nervous system (CNS).

How does the spinal cord carry information?

Like the brain, the spinal cord consists of gray and white matter. The butterfly-shaped center of the cord consists of gray matter. The front wings (usually called anterior or ventral horns) contain motor nerve cells (neurons), which transmit information from the brain or spinal cord to muscles, stimulating movement.

Can spinal cord tumors be removed?

Astrocytomas of the spinal cord usually cannot be removed completely. They may be treated with surgery to obtain a diagnosis and remove as much tumor as possible, and then by radiation therapy, or with radiation therapy alone. Chemotherapy might also be an option at some point, if needed.

What marks the end of the spinal cord?

The spinal cord ends at the level of vertebrae L1–L2, while the subarachnoid space —the compartment that contains cerebrospinal fluid— extends down to the lower border of S2. Lumbar punctures in adults are usually performed between L3–L5 (cauda equina level) in order to avoid damage to the spinal cord.

Where is the spinal cord found?

spinal column
The spinal cord lies inside the spinal column, which is made up of 33 bones called vertebrae. Five vertebrae are fused together to form the sacrum (part of the pelvis), and four small vertebrae are fused together to form the coccyx (tailbone).

What does X-ray record of spinal cord mean?

How many nerve roots are there in the spinal cord?

This illustration shows the nerve roots of the spinal nerves coming out of the vertebrae. The axons that link the spinal cord to the muscles and the rest of the body are bundled into 31 pairs of spinal nerves, each pair with a sensory root and a motor root that make connections within the gray matter.

What are the ascending tracts of the spinal cord?

The ascending tracts of the spinal cord consist of sensory nerves that send signals from internal organs and external signals from the skin and extremities to the brain. Reflexes and repetitive movements are controlled by spinal cord neuronal circuits that are stimulated by sensory information without input from the brain. Spinal Nerves

How is the spinal cord connected to the rest of the body?

The axons that link the spinal cord to the muscles and the rest of the body are bundled into 31 pairs of spinal nerves, each pair with a sensory root and a motor root that make connections within the gray matter. These nerves must pass between the protective barrier of the spinal column to connect the spinal cord to the rest of the body.
