Nerve roots branch off from the spinal cord and exit the spinal column through small spaces called intervertebral foramina. The human spine is divided into five main regions It consists of 33 vertebrae, which protect the spinal cord and support body movement. 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 column can be divided into five different regions, with each region characterised by a different vertebral structure
Anatomically, the spine is divided into four regions The vertebrae are divided into different regions based on their location in the spine These are the vertebrae in the neck region and are numbered c1 to c7 They are smaller and more flexible than the other vertebrae, allowing for a greater range of motion in the neck. Spine anatomy is a complex structure made up of bones, joints, muscles, ligaments, and nerves It is typically divided into four sections
Explore the full anatomy of the spine including vertebrae, spinal cord, discs, ligaments, muscles, and nerves across all spinal regions. Some regions of the spine are more flexible than others The cervical spine is the most flexible It allows us to turn and tilt our head in nearly every direction The sacrum and tailbone can't be moved, and are made up of only bone in adults Children still have separate vertebrae making up the sacrum and tailbone, which then gradually grow.
