What are the bones of the shoulder complex? |
Sternum, clavicle, scapula and proximal-to-mid humerus |
|
|
What is arthrology? |
the science concerned with the study of anatomy, function, dysfunction and treatment of joints and articulations |
|
|
What four joints does the shoulder complex interact with? |
Sternoclavicular Scapulothoracic Acromioclavicular Glenohumeral |
|
|
What forms a functional roof for protection? |
Acromion |
|
|
Fingerlike projection of bone from the anterior surface of the scapula, palpable about 1 inch below the most concave portion of the distal clavicle. |
Coracoid process |
|
|
Allows the scapula to glide smoothly along the convex posterior rib cage. |
Subscapular fossa |
|
|
Sword shaped |
Xiphoid Process |
|
|
Acts like a mechanical rod that links 2 bone structures together |
Clavicle |
|
|
Borders the superior and inferior aspect of the glenoid fossa and serves as proximal attachment for the long head of the biceps and long head for the triceps |
Superior and inferior glenoid tubercles |
|
|
muscles attached to the clavicle and their respective attachments |
P=prox D=distal Pectoralis major-p Sternocleidomastoid-p Anterior deltoid-p Upper trap-d Subclavius-d |
|
|
Wide, flattened projection of bone from the most superior-lateral aspect of the scapula. |
Acromion process |
|
|
Breastbone |
Sternum |
|
|
Flat and lateral portion of the clavicle |
Acromial end |
|
|
Medial portion of the clavicle |
Sternal end |
|
|
The scapular spine divides the posterior aspect of the scapula into what two parts? |
Supraspinatous fossa-above Infraspunatous fossa-below |
|
|
Half full sphere that articulates with the glenoid fossa |
Humeral head |
|
|
Sharp, anterior projection of bone just below the humeral head |
Lesser tubercle |
|
|
Larger, more rounded lateral projection of bone |
Greater tubercle |
|
|
Distally on the lateral aspect of the upper 1/3 of the shaft of the humerus |
Deltoid tuberosity |
|
|
Runs oblique across the posterior surface of the humerus |
Radial groove |
|
|
Follows the radial groove |
Radial nerve |
|
|
Defines the distal attachment for the lateral and medial heads of the triceps. |
Radial nerve |
|
|
What muscles and their attachments connect to the posterior portion of the scapula |
Prox= Distal=d Posterior deltoid-p Supraspinatous-p Infraspinatous-p Teres minor-p Teres major-p Levator scapulae-d Rhomboid minor-d Rhomboid major-d Lower and middle trap-d Latissisum dorsi-p |
|
|
What muscles and their attachments connect to the anterior portion of the scapula? |
Prox=p Distal=d Subscapularis=p Long head of the triceps=p Middle deltoid=p Long head of the biceps=p Short head biceps=p Coracobrachialis=p Pectoralis minor-d Serratus anterior-d |
|
|
contains anterior and posterior fibers that firmly join the clavicle to the manubrium |
sternoclavicular ligament |
|
|
surrounds the entire SC joint; is reinforced by the anterior and posterior SC joint ligaments |
joint capsule |
|
|
Spans the jugular notch, connecting the superior medial aspects of the clavicles |
interclavicular ligament |
|
|
Firmly attaches the clavicle to the costal caritlage of the first rib and limits the extremes of all clavicular motion except depression |
costoclavicular ligament |
|
|
acts as a shock absorber between the clavicle and the sternum; helps improve congruency |
articular disc |
|
|
what type of joint is the SC joint? |
saddle joint |
