The vertebral column consists of seven cervical, twelve thoracic, and five lumbar segments. In adults, the cord terminates at the level of L1-L2. Thus the cord spans within 20 bony vertebrae. In a child, it terminates at the upper border of L3.
At what level does the spinal cord terminate?
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 spinal cord terminate in adult?
The spinal cord terminates at or below the upper third of L2. Care should be exercised during lumbar punctures and spinal epidural anesthesia among Africans. Intecristal line and TUP are safe landmarks to use in location of conus medullaris.
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 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.
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.
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 best thing to do for spinal stenosis?
Over-the-counter medications such as aspirin, ibuprofen (Advil, Motrin IB, others), naproxen (Aleve, others) and acetaminophen (Tylenol, others) can help reduce pain and inflammation. Applying hot or cold packs. Some symptoms of cervical spinal stenosis may be relieved by applying heat or ice to your neck.
What is considered the true spinal cord?
The spinal cord in an adult is approximately a 45 cm long, cylindrical structure that is slightly flattened anteriorly and posteriorly. The spinal cord lies within the vertebral canal, extending from the foramen magnum to the lowest border of the first lumbar vertebra.
What nerve passes from the spinal cord into the limbs?
brachial plexus: A network of nerve fibers, running from the spine, formed by the ventral rami of the lower four cervical and first thoracic nerve roots (C5–C8, T1). It proceeds through the neck, the axilla (armpit region), and into the arm. It also supplies the brachium, the antebrachium, and the hand.
