Study Notes
Thoracic Spine
- Thoracic spine body is bigger and heart-shaped compared to other spine types
- Vertebral foramen is larger
- Lamina, pedicle, spinous process, transverse process, superior articular facet, inferior articular facet, superior costal facet, inferior costal facet and transverse costal facet are all parts of the thoracic spine
- The costal facet articulates with the head of a rib, located on the transverse process for articulation with the tubercle of a rib
Lumbar Spine
- Lumbar spine body is bigger than the thoracic spine because it carries the most body weight
- Transverse processes increase in size from top to bottom
- 5th transverse process is shorter, stronger and pyramidal
- Spinous processes are square and horizontal
- Spinal cord ends at the lower border of the first lumbar vertebra
Sacrum
- 5 fused vertebrae forming a triangular shape
- Concave anteriorly
- Forms the sacroiliac joint with the ilium
Coccyx
- 4 (3-5) fused vertebrae
- Different shape and size
- Articulates at an acute angle with the sacrum
Vertebral Levels
- Provides a guide for locating specific vertebrae relative to external anatomical landmarks.
- Includes landmarks such as the mastoid process, thyroid cartilage, vertebral prominence, suprasternal notch, sternal angle, inferior angle of the scapula, xyphoid process, inferior costal margin, iliac crest, anterior superior iliac spine, greater trochanter, and symphysis pubic.
- Corresponding vertebral levels are given for each landmark. Information on approximate location in the vertebral column.
Congenital Fusion
- Congenital fusion of the lowest lumbar vertebra to the top of the sacrum is called sacralization.
- Incomplete development of the spine and lamina can result in absence of the posterior wall, which is called Spina bifida.
