How many articulations does the scapula have?

There are four joints making up the ‘shoulder joint’: The shoulder joint itself known as the Glenohumeral joint, (is a ball and socket articulation between the head of the humerus and the glenoid cavity of the scapula) The acromioclavicular (AC) joint (where the clavicle meets the acromion of the scapula)

What are the 5 articulations of the shoulder?

3.1 Glenohumeral Joint.

What does the scapular spine articulate with?

The acromion process is a palpable lateral and enlarged extension of the posterior spine of the scapula which projects anterolaterally to the spine. It arches over the glenohumeral joint and articulates with the lateral acromial end of the clavicle to make up the synovial acromioclavicular joint.

What articulates the scapula to the humerus?

The scapula is flat and triangular. The scapula articulates with the humerus at the glenoid fossa and the clavicle at the acromion process.

What are the three major articulations of the shoulder?

The shoulder girdle is composed of the clavicle and the scapula, which articulates with the proximal humerus of the upper limb. Four joints are present in the shoulder: the sternoclavicular (SC), acromioclavicular (AC), and scapulothoracic joints, and glenohumeral joint.

What are the two articulations of the elbow joint?

The elbow joint consists of two types of articulations and thus allows two types of motion. The ulnohumeral articulation resembles a hinge joint, allowing flexion and extension, whereas the radiohumeral and proximal radioulnar joint allows axial rotation (Morrey 1986).

What are the three major articulations of the shoulder quizlet?

The bones that comprise the shoulder complex and shoulder joint are the clavicle, scapula, and humerus. These three bones form the four major articulations associated with the shoulder complex: the sternoclavicular joint, the acromioclavicular joint, the glenohumeral joint, and the scapulothoracic joint.

What bone articulates with the acromion process?

clavicle
The spine ends in the acromion, a process that articulates with the clavicle, or collarbone, in front and helps form the upper part of the shoulder socket.

What bone articulates with the glenoid cavity?

humerus
part of scapula …presents a shallow cavity, the glenoid cavity, which articulates with the head of the bone of the upper arm, the humerus, to form the shoulder joint.

Does the clavicle articulate with the scapula?

The clavicle articulates with the scapula here, at the tip of the acromion. This other projection, looking like a bent finger, is the coracoid process. Here’s how the clavicle and the scapula look in the living body.

What are the 4 articulations of the shoulder?
