Study Notes
Cervical Vertebrae
- The first cervical vertebra is known as the atlas.
- The atlas contains a distinctive feature called the posterior tubercle which serves as an attachment point for ligaments and muscles.
Axis
- The second cervical vertebra is known as the axis.
- A key feature of the axis is the odontoid process (or dens), which allows for rotation of the head.
Total Cervical Vertebrae
- There are a total of seven cervical vertebrae in the human spine.
Thoracic Vertebrae
- Thoracic vertebrae are characterized by the presence of costal facets, which articulate with the ribs.
Sacrum Anatomy
- The lateral parts of the sacrum contain sacral foramina, which are openings for nerve roots and blood vessels.
- The sacrum itself includes five fused vertebrae forming a triangular structure at the base of the spine.
Sternum Structure
- The sternum consists of three main parts: the manubrium, the body, and the xiphoid process.
Scapula Features
- The back of the scapula is marked by the spine of the scapula, an elevation that leads to the acromion.
- The scapula has two primary surfaces: the anterior (costal) surface, which faces the ribcage, and the posterior (dorsal) surface, which features the supraspinous and infraspinous fossae.
