Costal Facets, Demifacets, and Rib-Vertebral Articulations

The video provides an in-depth look at the human rib structure, focusing on how ribs articulate with the vertebrae. It explains the typical rib anatomy, including the head, neck, tubercle, and angle, and how these parts connect to the vertebrae. The video also discusses the concept of demi facets and their role in rib articulation, highlighting the costovertebral and costotransverse joints. Additionally, it touches on the constraints ribs impose on thoracic spine mobility and previews future topics on rib ligaments and sternum joints.
