Clavicular facet of scapula is small oval facet on the medial border of the acromion for articulation with the acromial facet on the lateral end of the clavicle. [1] Also called Clavicular articular facet of acromion. The coracoacromial ligament is attached near the clavicular facet. [2]
When the scapula is moved laterally it lies in a sagittal plane with the glenoid cavity facing anteriorly. At this position, the lateral end of the clavicle is rotated anteriorly so that the clavicle lies in a frontal plane. While this slightly closes the angle between the clavicle and the scapula, it also widens the shoulder. [4]: 40
It fixes the scapula into the thoracic wall and aids in rotation and abduction of the shoulders. [citation needed] subclavius: Located beneath the clavicle, originating from the first rib and inserting on the subclavian groove of the clavicle. [3] It depresses the lateral clavicle [3] and also acts to stabilize the clavicle. [citation needed ...
It joins with the scapula above at the shoulder joint (or glenohumeral joint) and with the ulna and radius below at the elbow joint. Notice : When the arm is spun so that the thumb point to the outside of the body, meaning the palm of the hand looks forward then it is said the hand is supinated.
The infraspinous fossa (infraspinatus fossa or infraspinatous fossa) of the scapula is much larger than the supraspinatous fossa; toward its vertebral margin a shallow concavity is seen at its upper part; its center presents a prominent convexity, while near the axillary border is a deep groove which runs from the upper toward the lower part.
The scapula (pl.: scapulae or scapulas [1]), also known as the shoulder blade, is the bone that connects the humerus (upper arm bone) with the clavicle (collar bone). Like their connected bones, the scapulae are paired, with each scapula on either side of the body being roughly a mirror image of the other.
The acromioclavicular ligament, which attaches the clavicle to the acromion of the scapula. Superior acromioclavicular ligament. This ligament is a quadrilateral band, covering the superior part of the articulation, and extending between the upper part of the lateral end of the clavicle and the adjoining part of the upper surface of the acromion.
The root of the spine of the scapula is the most medial part of the scapular spine. It is termed "triangular area of the spine of scapula", based on its triangular shape giving it distinguishable visible shape on x-ray images. [1] The root of the spine is on a level with the tip of the spinous process of the third thoracic vertebra. [2]
