Study Notes
Thoracic Vertebrae
- Characteristic feature of typical thoracic vertebrae includes long, downward-sloping spinous processes and facets for rib articulation.
Rib Articulation
- The head of a typical rib articulates with the bodies of two adjacent thoracic vertebrae and the intervertebral disc between them.
Sternal Angle
- The sternal angle, also known as the angle of Louis, is located at the level of the second rib and corresponds to the T4-T5 intervertebral disc.
Intercostal Muscles
- Intercostal spaces are occupied by three layers of muscles: external intercostals, internal intercostals, and innermost intercostals, which assist in breathing.
