    Study Notes

    Anatomy of the Vertebrae and Thoracic Cage

    • The vertebrae consist of the spinous process, transverse process, vertebral arch, vertebral foramen, and intervertebral foramen.
    • Each vertebra has intervertebral foramen, superior and inferior articular facets, and articulates with adjacent vertebrae.
    • Intervertebral discs absorb stress and prevent vertebrae from grinding against each other, with anulus fibrosus and nucleus pulposus as their components.
    • The cervical vertebrae include the Atlas (C1) and Axis (C2), with distinct features such as the absence of a body or spinous process in Atlas and the dens elevation in Axis.
    • Thoracic vertebrae have costal facets for articulation with the ribs and resemble the head of a giraffe.
    • Lumbar vertebrae have large transverse processes and short spinous processes, resembling the head of a moose.
    • The sacrum has various features including the superior border, promontory, sacral canal, and sacral foramina, and articulates with the coccyx at the apex.
    • The thoracic cage, consisting of ribs, sternum, and thoracic vertebrae, protects the heart and lungs.
    • The sternum includes different regions such as the manubrium, body, xiphoid process, and costal notches for articulation with the ribs.
    • Ribs are classified into true ribs (1-7) and false ribs (8-12), and articulate with the thoracic vertebrae via their head and tubercle.
    • The articulation between thoracic vertebrae and ribs involves the head of the rib and the tubercle articulating with costal facets and demifacets of the vertebrae.
    • The anatomy of the vertebrae and thoracic cage is essential for understanding the structure and function of the spine and ribcage.
