Question

in a(n) ____ dislocation, the head of the humerus is forced out of its articular capsule in an anterior direction past the glenoid labrum and then downward to rest under the coracoid process.

Answer 1

An anterior dislocation of the shoulder occurs when the head of the humerus is displaced from its capsule in a forward direction, moving past the glenoid labrum and beneath the coracoid process.

Step-by-step explanation:

In a anterior dislocation of the shoulder, the head of the humerus is forced out of its articular capsule in an anterior direction past the glenoid labrum and then downward to rest under the coracoid process. Injuries to the shoulder joint, such as dislocations, are often associated with activities that involve repetitive use of the upper limb. Most dislocations of the humerus occur in an inferior direction as the humeral head is strongly supported by muscles and ligaments around its anterior, superior, and posterior aspects.

A traumatic force to the humerus when the upper limb is fully extended, like diving to catch a ball, can lead to such dislocations.
