The spinal cord is attached to the dura by a series of lateral denticulate ligaments emanating from the pial folds. The three spinal cord meninges. The denticulate ligament, the dorsal root ganglion (A), and an enlarged drawing of the meninges (B).
What is the spinal cord attached to?
Like the brain, the spinal cord is covered by the meninges and cushioned by cerebrospinal fluid. Spinal nerves connect the brain with the nerves in most parts of the body. Other nerves go directly from the brain to the eyes, ears, and other parts of the head.
What structure ends up as spinal cord?
The spinal cord is a long, thin, tubular structure made up of nervous tissue, which extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column. It encloses the central canal of the spinal cord, which contains cerebrospinal fluid.
What is the spinal cord structure?
The spinal cord is a long cylinder of nerves that runs from the base of your brain through the vertebral canal through the backbone. It is part of the central nervous system (CNS) along with the brain. It is divided into different segments. Each segment contains a pair roots made out of nerve fibres.
What happens if a tethered spinal cord goes untreated?
Consequences of Untreated Tethered Cord
Patients with untreated tethered cord will continue to experience their current symptoms, and their motor and sensory function may worsen. Particularly in children, lengthening of the spine with growth can lead to paraplegia and loss of bowel and bladder function.
How is spine numbered?
The spinal nerves are numbered according to the vertebrae above which it exits the spinal canal. The 8 cervical spinal nerves are C1 through C8, the 12 thoracic spinal nerves are T1 through T12, the 5 lumbar spinal nerves are L1 through L5, and the 5 sacral spinal nerves are S1 through S5. There is 1 coccygeal nerve.
What is the structure and function of spinal cord?
Spinal cord and nerves: The spinal cord is a column of nerves that travels through the spinal canal. The cord extends from the skull to the lower back. Thirty-one pairs of nerves branch out through vertebral openings (the neural foramen). These nerves carry messages between the brain and muscles.
What are the parts of a spine?
The spine is composed of 33 bones, called vertebrae, divided into five sections: the cervical, thoracic, and lumbar spine sections, and the sacrum and coccyx bones. The cervical section of the spine is made up of the top seven vertebrae in the spine, C1 to C7, and is connected to the base of the skull.
How long does tethered spinal cord surgery take?
The procedure lasts two to four hours. Although each child’s experience is different, a typical hospital stay after a tethered cord release lasts four to seven days. If your child has the procedure, they will likely be hospitalized in the Neurosciences Unit. Here, they rest flat in bed for 24 to 72 hours after surgery.
Is a tethered spinal cord painful?
In adults, symptoms of tethered cord often develop slowly, but they can become quite severe. Symptoms may include back pain that radiates to the legs, hips, and the genital or rectal areas. The legs may feel numb or weak, and may lose muscle. Bladder and bowel control may be difficult.
