humeral head

The shoulder joint is made up of the glenoid and humeral head.

The greater tubercle projects as the most lateral structure of the humeral head.

Medial to this, in turn, is the lesser tuberosity of the humeral head.

It also helps stabilize the humeral head in the glenoid cavity.

The humeral head is around 29mm wide.

In burrowing moles, the clavicle and the humeral head are connected.

It is caused by a hyper abduction of the arm that forces the humeral head against the acromion.

Thus, the position chosen involves weighing concerns about lymph nodes, lung, and humeral heads.

When this happens, a pocket at the front of the glenoid forms that allows the humeral head to dislocate into it.

Such a tear usually occurs at its point of insertion onto the humeral head at the greater tubercle.

The cuff adheres to the glenohumeral capsule and attaches to the humeral head.

There was no appearance of ossification in the humeral head, though the cuboid was ossified.'

The humeral head arises from the medial epicondyle of the humerus by the common flexor tendon.

It is an indication for surgery and often accompanied by a Hill-Sachs lesion, damage to the posterior humeral head.

A metal ball is used to replace the humeral head and a plastic socket replaces the cartilage on the glenoid cavity.

It appears as a curved subchondral radiolucent line that is oftentimes found on the proximal femoral or humeral head.

The humeral head is ball shaped but the glenoid is more dish shaped than cup shaped.

An important function of the deltoid in humans is preventing the dislocation of the humeral head when a person carries heavy loads.

The shoulder is brought back to resting position and the shoulder external rotation is repeated, this time with posteriorly directed force over the humeral head.

It results from forceful impaction of the humeral head against the anteroinferior glenoid rim when the shoulder is dislocated anteriorly.

The largest Enantiornithine from the Early Cretaceous is Pengornis, with a humeral head width of (17mm).

The deltoid is responsible for elevating the arm in the scapular plane and its contraction in doing this also elevates the humeral head.

This is due to the compression of the supraspinatus tendon or subacromial bursa between the anterior acromial arch and humeral head.

In 1940, the pair published a report of 119 cases of shoulder dislocations and showed that the defect resulted from direct compression of the humeral head.

Pengornis shows characters of the humeral head, acromion, and anterior cervical vertebrae, that were previously known only in members of the Ornithurae.
