Study Notes
Vertebral Column and Thoracic Cage
- The first cervical vertebra is termed atlas (C1).
- The second cervical vertebra is referred to as axis (C2).
- The lumbar curve is the inward curvature of the lower back.
- All ribs connect with the vertebrae.
- Both radiographs and CT scans utilize radiation to create images of anatomical structures.
- Kyphosis results in an exaggerated thoracic curve, causing a humpback appearance.
- The sacrum and coccyx consist of fused vertebrae.
- The upper section of the sternum is called the manubrium.
- The hyoid bone is unique as it does not articulate with any other bone.
- The sacral canal is a vertical passage through the sacrum for nerve transmission from the spinal cord.
- The spinous process of vertebrae creates the bumps along the midline of the back.
- Floating ribs do not connect to the sternum directly or indirectly.
- True ribs attach directly to the sternum.
- Costal cartilages are made of hyaline cartilage.
- Intervertebral disks act as joints between the bodies of adjacent vertebrae.
- The hyoid bone is notably shaped like a horse.
- The coccyx is commonly known as the tailbone.
- Spinal nerves exit the vertebral column through openings called intervertebral foramina.
- The medial sacral crest is the ridge on the posterior surface of the sacrum.
