This video is part of a playlist dealing with the "Osteology of the thoracic cage." Although each video in the playlist can be watched separately, it is recommended that the playlist is watched in the following sequence:
1. Osteology of the sternum • Osteology of thoracic ...
2. Osteology of the ribs and costal cartilages • Osteology of the thora...
3. Osteology of the thoracic vertebrae • Osteology of the thora...
After watching this video. it is expected that you will be able to
Objectives:
Identify the costal cartilages and outline their articulations (costochondral, chondrosternal and chondrochondral joints).
Identify the parts of the typical rib (body, neck, head, tuberosity, articular facets, costal groove, and angle).
Identify the borders and surfaces of the rib (superior and inferior border; external and internal surfaces),
Explain the terms, related to ribs: Typical/atypical; true/false; fixed/floating.
Recall missing and supernumerary ribs (cervical and lumbar ribs).
Describe the mode of articulation of a rib with a thoracic vertebra (costovertebral and costotransverse joints).
List the atypical ribs and identify the characteristic features of each: first, second, eleventh and twelfth ribs.
Identify scalene tubercle on the first rib and tuberosity for serratus anterior on the second rib.
Describe the relations of structures on the superior surface of the first rib.
