Study Notes
Vertebral Column Study Notes
- Intervertebral discs provide cushioning between vertebrae, allowing for flexibility and shock absorption.
- Cervical vertebrae consist of seven bones (C1-C7) in the neck region, enabling head movement and supporting the skull.
- Thoracic vertebrae comprise twelve bones (T1-T12) in the upper and mid-back, serving as attachment points for ribs.
- The cervical region refers to the area of the spinal column housing the cervical vertebrae.
- The thoracic region is where the thoracic vertebrae are located, forming the posterior part of the rib cage.
- The first cervical vertebra, known as the atlas, supports the skull and allows nodding movement.
- The second cervical vertebra, called the axis, permits rotational movement of the head.
- The first thoracic vertebra, T1, connects with the upper ribs and is positioned at the junction of the cervical and thoracic regions.
- Intervertebral discs not only cushion but also enable movement between adjacent vertebrae.
- Lumbar vertebrae include five vertebrae (L1-L5) in the lower back, characterized by larger bodies for weight-bearing support.
- The sacrum is a triangular bone composed of five fused vertebrae, connecting the spine to the pelvis.
- The coccyx, or tailbone, is formed from three to five fused vertebrae at the base of the spine, serving as an attachment point for ligaments and muscles.
- The lumbar region encompasses the area of the lumbar vertebrae, providing support and stabilization for the upper body.
- The sacral and coccygeal regions refer to the areas encompassing the sacrum and coccyx, contributing to pelvic structure and function.
- The first lumbar vertebra, L1, marks the transition between thoracic and lumbar regions, supporting the lower back.
- Transverse processes are bony projections on either side of a vertebra, serving as muscle attachment sites.
- Spinous processes are the bony protrusions on the back of a vertebra, aiding in muscle and ligament attachment for spinal stability.
