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.
Where does the spinal cord end?
The spinal cord begins at the bottom of the brain stem (at the area called the medulla oblongata) and ends in the lower back, as it tapers to form a cone called the conus medullaris.
Does the spinal cord end at L5?
The L5 vertebra is the final section of the lumbar spine (at least, it is for most people). Injury to the L5 spinal nerve bundle can cause numbness and weakness in the legs, but the extent of these symptoms can vary from case to case.
What vertebral body does the spinal cord end?
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. A few anatomical structures related to the lumbar spinal cord are highlighted below.
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.
What are the symptoms of L2 nerve damage?
For example, if you have a bulging disc between the 2nd and 3rd lumbar vertebra (L2-L3), and it pinches the L2 nerve root, you may experience back pain with aching, burning or shooting pain, numbness and tingling in the thigh, sometimes going down into the lower leg or foot.
Why does the spinal cord end at L2?
Although the spinal cord cell bodies end around the L1/L2 vertebral level, the spinal nerves for each segment exit at the level of the corresponding vertebra. For the nerves of the lower spinal cord, this means that they exit the vertebral column much lower (more caudally) than their roots.
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.
What are the symptoms of L5 nerve damage?
L5 NERVE ROOT DAMAGE
A pinched L5 nerve root usually results in radiating pain in the foot. This pain can come in the form of numbness, tingling, weakness and shooting and is commonly felt in the big toe, inside of the foot, top of the foot and ankle.
What is the C spine?
About the cervical spine
The cervical spine refers to the seven spinal bones (vertebrae) in the neck. It supports the head and connects to the thoracic spine. Most of the ability to turn the head comes from the top two segments of the cervical spine.
What part of your spine controls your legs?
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.
What are the levels of the spine?
There are four sections of the spinal cord: cervical, thoracic, lumbar and sacral. Each section of the spine protects different groups of nerves that control the body.
