Find out about the vertebral or spinal column/backbone - what are the bones of the vertebra, anatomy, structure, and functions, along with labeled diagrams.
Spine. The spinal cord begins at the base of the brain and extends into the pelvis. Many of the nerves of the peripheral nervous system, or PNS, branch out from the spinal cord and travel to...
The spine is divided into four regions which contain vertebrae: the cervical, the thoracic, the lumbar, and the sacral. Hover over each part to see what they do. Vertebrae Connections & Functions.
The spine, also known as the vertebral column or spinal column, is a column of 26 bones in an adult body --- 24 separate vertebrae interspaced with cartilage, and then additionally the sacrum and coccyx.
The entire spinal column consists of 33 individual bones called vertebrae, plus two sections of naturally fused vertebrae – the sacrum and the coccyx – located at the very bottom of the spine. All of these bones and sections are important to the spine’s ability to function properly.
Below is a chart that outlines the main functions of each of the spine nerve roots: Nerve Plexuses. It is important to mention that after the spinal nerves exit from the spine, they join together to form four paired clusters of nerves, or nerve networks, called plexuses.
Keep learning about the white and grey matter of the spinal cord using our spinal cord diagram labeling exercises and quizzes! Solidify your knowledge about the spinal cord structures with our interactive study materials.
Your spine is the long column of bones that extend from your neck to your lower back. Your spine starts at the base of your skull (head bone) and ends at your tailbone, a part of your pelvis (the large bony structure between your abdomen and legs).
The spinal cord consists of a densely packed column of nerve tissue, which runs from the brainstem to around L1-2 in adults. [1] . The terminal end of the spinal cord is the conus medullaris. The cauda equina extends from the conus medullaris. [2] .
The spinal cord comprises three parts: the cervical (neck), thoracic (chest), and lumbar (lower back) regions. Three layers of tissue protect the spinal cord: the dura mater, arachnoid mater,...
