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.
At what level of the spine does the spinal cord end?
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?
The spinal cord ends around the L1 or L2 vertebrae in adults, forming the conus medullaris. The horsetail shaped area, which extends past the conus medullaris, is called the cauda equina. How many vertebrae are in the spine?
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 is the 4 spinal cord region?
The spinal cord is divided into four different regions: the cervical, thoracic, lumbar and sacral regions (Figure 3.1).
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. The range of motion in the thoracic spine is limited. Lumbar (low back) – the main function of the lumbar spine is to bear the weight of the body.
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.
Why does the spinal cord hurt?
Conditions commonly linked to back pain include: Muscle or ligament strain. Repeated heavy lifting or a sudden awkward movement can strain back muscles and spinal ligaments. If you’re in poor physical condition, constant strain on your back can cause painful muscle spasms.
What are the 3 areas of the spine?
The spine has three normal curves: cervical, thoracic and lumbar. There are seven cervical vertebrae in the neck, 12 thoracic vertebrae in the torso and five lumbar vertebrae in the lower back.
Is spinal cord a nerve?
The spinal cord consists of bundles of nerve axons forming pathways that carry incoming and outgoing messages between the brain and the rest of the body. The spinal cord contains nerve cell circuits within itself that control coordinated movements such as walking and swimming, as well as urinating.
