The frontal attack is usually the least desirable form of maneuver because it exposes the majority of the offensive force to the concentrated fires of the defenders. The battalion may conduct a frontal attack against a stationary or moving enemy force (Figure 4-6).
All of the twelve ribs articulate posteriorly with the vertebrae of the spine. Each rib forms two joints: Costotransverse joint â Between the tubercle of the rib, and the transverse costal facet of the corresponding vertebrae.
In the dry skeleton, here's the clavicle, here's the scapula. The proximal long bone of the upper extremity, the humerus, articulates with the scapula at the shoulder joint. The scapula and clavicle articulate with the bones of the thorax at one point only, here, at the sternoclavicular joint. The lateral end of the clavicle articulates with this projection on the scapula, the acromion, forming the acromio-clavicular joint.
