Shoulder Region Flashcards
It is the most cephalic aspect of the sternum
Manubrium
Clavicle is s-shaped, with its forward ___ at its sternal end and forward ___ at its Humeral end
Convexity, concavity
Anatomical resting position of the scapula, with its medial border is approximately ___ from the thoracic spinous processed
5-6 cm or 2-3 finger widths
Anatomical resting position of the scapula, with its medial border is approximately ___ from the thoracic spinous processes
5-6 cm or 2-3 finger widths
Thoracic levels of the spine of scapula, the root of the spine of scapula and it’s inferior angle
T2, T3, T7
The scapula is rotated on its transverse axis approximately __ to ___ so the glenoid fossa is tilted anterior to the frontal plane
30°-45°
The head of the humerus is the __ segment that interfaces with the __ glenoid fossa to form the GH joint
Convex, concave
The head is 1/3-1/2 of a sphere and it is positioned __ and __ in the frontal plane
Medially and superiorly
The head is rotated posteriorly in the transverse plane to meet the glenoid fossa that usually faces slightly __, ___ and __ direction
Lateral, superior and anterior
In the frontal plane, the Humeral head is angled at __° to the long axis of the Humeral shaft. This angle is called
135° , angle of inclination
Relative to the shaft of the humerus.
Angle of torsion
Relative position of posterior rotation is called __ and is usually __°
Retroversion , 30°
Sits lateral to the lesser tubercle and is a large round protuberance
Greater tubercle
Smaller and sharper and lies more medially
Lesser tubercle
It separates the two tubercle, and an indentation through which the __ runs from its proximal insertion in the supra glenoid tubercle
Bicipital groove, long head of biceps
A circumferential area on the proximal humerus. This region is distal to the bicipital groove and it is a common site of Humeral fracture
Surgical neck
Result of the SC and AC joint working together to produce scapulothoracic movement
Scapula motion
Scapula slides upward on the thorax relative to it’s resting position
Shoulder girdle elevation
Reverse movement of elevation in which the scapula slides downward on the thorax
Shoulder girdle Depression
The movement of shoulder depression can elevate the trunk __ inches or __ cm
4-6 inches / 10-15 cm
Lateral end of clavicle and the scapula move anteriorly around the rib cage with the medial border of scapula moving away from the midline __inches or __ cm
Shoulder girdle protraction
5-6 inches / 13-15 cm
Lateral end of clavicle and the scapula move posteriorly and the medial border of scapula approaches the midline.
Shoulder girdle retraction
At the Sternoclavicular joint, the total range for protraction and retraction is approximately __°
25°
Glenoid fossa moves to face superiorly and the inferior angle of the scapula slides laterally and anteriorly in the thorax
Shoulder girdle Upward rotation
