The spinal cord terminates in the lumbar spine. The exact point of termination varies among individuals; most commonly, it terminates at the level of the L1 or L2 vertebrae.
Which vertebrae does the spinal cord end at?
The spinal cord tapers and ends at the level between the first and second lumbar vertebrae in an average adult. The most distal bulbous part of the spinal cord is called the conus medullaris, and its tapering end continues as the filum terminale.
Does spinal cord end at l4?
In human, the spinal cord ends at L2 vertebral level. The tip of the spinal cord is called the conus. Below the conus, there is a spray of spinal roots that is frequently called the cauda equina or horse’s tail. Injuries to T12 and L1 vertebra damage the lumbar cord.
Does the spinal cord end at L3?
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 does the spinal cord start and end?
About the spinal cord and nerve roots
The spinal cord originates in the brain, exiting through a hole at the skull base called the foramen magnum and coursing through the spinal canal of the cervical, thoracic and upper lumbar spine before ending most commonly between the first and second lumbar vertebrae.
What part of the spine controls the heart?
Thoracic (mid back) – the main function of the thoracic spine is to hold the rib cage and protect the heart and lungs. The twelve thoracic vertebrae are numbered T1 to T12.
Is L4-L5 curable?
Treatment of the L4-L5 spinal motion segment typically begins with nonsurgical methods. In cases where the back and/or leg symptoms do not improve with nonsurgical treatments, or in case of certain medical emergencies, surgery may be considered.
What is the best treatment for lumbar spinal stenosis?
One of the most effective treatments for treating lumbar spinal stenosis is a procedure called laminectomy. This treatment removes part of the vertebra that’s putting pressure on your nerve.
Is lumbar part of spine?
The lumbar region of the spine, more commonly known as the lower back, consists of five vertebrae labeled L1 through L5. The lumbar region is situated between the thoracic, or chest, region of the spine, and the sacrum.
What is C4 spinal injury?
A C4 spinal cord injury occurs when damage is dealt about mid-way down the cervical spinal cord — the topmost portion of the spinal cord that is located in the neck and upper shoulders.
Which spinal nerves affect which parts of the body?
The nerves of the cervical spine go to the upper chest and arms. The nerves in your thoracic spine go to your chest and abdomen. The nerves of the lumbar spine then reach to your legs, bowel, and bladder. These nerves coordinate and control all the body’s organs and parts, and let you control your muscles.
