What does the glenoid cavity articulates with?
What does the glenoid cavity articulates with?
head of humerus
The shallow glenoid fossa or the glenoid cavity articulates with the head of humerus. Its upper end has the supraglenoid tubercle for the long head of the biceps.
Is the glenoid cavity an articulating surface?
On the lateral border of the scapula is a shallow pyriform, articular surface, the glenoid cavity, which is directed lateralward and forward and articulates with the head of the humerus; it is broader below than above and its vertical diameter is the longest.
What surrounds the glenoid cavity?
Extra stability to the glenohumeral joint is provided by the glenoid labrum, a ring of fibrous cartilage that surrounds the glenoid cavity. The glenoid labrum increases the depth and surface area of the glenoid cavity to provide a more secure fit for the half-spherical head of the humerus.
What bone articulates with the scapula at the glenoid fossa?
humerus
The scapula articulates with the humerus at the glenoid fossa and the clavicle at the acromion process.
Which part of humerus articulates with glenoid cavity?
The proximal portion of the humerus can be divided into three parts. The rounded humeral head projects medially and articulates with the glenoid cavity of the scapula. Immediately adjacent to the head is the narrower anatomical neck, which allows for a wider range of movements of the head within the shoulder joint.
What is the role of glenoid cavity?
Strong glenohumeral ligaments and muscles prevents dislocation in most cases. By being so shallow the glenoid cavity allows the shoulder joint to have the greatest mobility of all joints in the body, allowing 120 degrees of unassisted flexion.
Which bone articulates with the humerus via the glenoid cavity?
The scapula articulates with the humerus at the glenoid fossa and the clavicle at the acromion process.
What is glenoid cavity?
n. The hollow in the head of the scapula into which the head of the humerus sits to make the shoulder joint. glenoid fossa.
What is the main function of the glenoid cavity?
What bone articulates with 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.
Which bone articulates with the scapula at the glenoid cavity quizlet?
The humerus articulates with the scapula at the glenoid cavity to form the shoulder joint. This joint is also known as the glenohumeral joint, which is reinforced and stabilized by various ligaments and muscles. The ulna and radius form the bones of the forearm.
What articulates with the head of the humerus?
At its proximal end is the head of the humerus. This is the large, round, smooth region that faces medially. The head articulates with the glenoid cavity of the scapula to form the glenohumeral (shoulder) joint.
