Does the spinal cord end at the conus medullaris?

The spinal cord ends at the intervertebral disc between the first and second lumbar vertebrae as a tapered structure called the conus medullaris, consisting of sacral spinal cord segments.

What is a spinal cord Conus?

Conus medullaris – The cone-shaped bottom of the spinal cord, usually at the level of L1. Disc (Intervertebral) – A tough, elastic cushion located between the vertebrae in the spinal column; acts as a shock absorber for the vertebrae.

What does the conus medullaris contain?

The conus medullaris is the bundled, tapered end of the spinal cord nerves. Situated near the first two lumbar vertebrae, the conus medullaris ends at the cauda equina, a bundle of spinal nerves and nerve roots.

What spinal level is the conus medullaris?

After the cord terminates, the nerve roots descend within the spinal canal as individual rootlets, collectively termed the cauda equina. The conus medullaris most commonly terminates at the L1/2 intervertebral disc level in children and adults 1-3.

What is the treatment for conus medullaris?

Depending on its cause, spinal decompression surgery, radiation, and antibiotics can be used to treat the symptoms. In addition, physical therapy is also necessary to regain function.

What is the function of conus medullaris?

Structure and Function This structure serves to stabilize the spinal cord by connecting the conus to the coccyx via the coccygeal ligament. The lumbosacral nerve roots continue inferiorly to this as the cauda equina.

Is conus medullaris syndrome rare?

Primary glioblastoma multiforme of the conus medullaris is extremely rare and generally fatal.

What causes conus medullaris?

Conus medullaris syndrome is caused by an injury or insult to the conus medullaris and lumbar nerve roots. It is a clinical subset of spinal cord injury syndromes. Injuries at the level of T12 to L2 vertebrae are most likely to result in conus medullaris syndrome.

What causes conus medullaris syndrome?

How do you treat conus medullaris?

Where does the conus medullaris end in the spinal cord?

Conus Medullaris Syndrome The conus medullaris is the bundled, tapered end of the spinal cord nerves. Situated near the first two lumbar vertebrae, the conus medullaris ends at the cauda equina, a bundle of spinal nerves and nerve roots. Consequently, problems with the conus medullaris often affect the cauda equina.

Which is a secondary form of conus medullaris syndrome?

Conus Medullaris Syndrome Conus medullaris syndrome is a secondary form of spinal cord damage resulting from injuries to the lumber vertebrae. The conus medullarisis the bundled, tapered end of the spinal cord nerves.

Which is the tapered end of the spinal cord?

The conus medullarisis the bundled, tapered end of the spinal cord nerves. Situated near the first two lumbar vertebrae, the conus medullaris ends at the cauda equina, a bundle of spinal nerves and nerve roots. Consequently, problems with the conus medullaris often affect the cauda equina.

Which is the downward extension of the medulla oblongata?

It is a downward extension of the medulla oblongata after it passes through the foramen magnum. The lowermost tapering extremity of the spinal cord is called the conus medullaris, which is around the first or second lumbar vertebra and can sometimes be lower. [1] The upper border of the conus medullaris is usually poorly defined.
