Shoulder/Pectoral Flashcards
Joints of the Shoulder
Acromioclavicular joint
Scapulothoracic joint
Glenohumeral joint
Sternoclavicular joint
Sternoclavicular Joint ligaments
anterior/posterior sternoclavicular ligaments (limits depression)
Articular disc divides the joint
costoclavicular ligament is underneath the clavicle (limits elevation and protraction)
AC Joint Ligaments
Superior and Inferior AC ligamnets Coracoclavicular Ligament (Conoid (medial) and Trapezoid)
Ligament that creates a roof over GH joint
coracoacromial ligament.
attaches from the acromion to the corocoid process
When we elevate our arm, the clavicle does what?
Rotates posteriorly
the sternal end depresses
the lateral end elevates and slides anteriorly
Triangle of Auscultation
bounded by the trapezius, rhomboid major, and latissimus doors
where you can hear lung sounds best
Triangular Space
Teres Minor, Teres Major, long head of Triceps
contains the circumflex scapular artery
Triangular Interval
bounded by long head and lateral head of tricep and the Teres Major
contains the radial nerve and profunda brachii artery
Quadrangular Interval
bounded by Teres Minor, Teres Major, Humerus, and Long head of the Triceps
contains the axillary nerve and the posterior humeral circumflex artery
Clavipectoral Triangle
bordered by the clavicle, pectoralis major, and deltoid
where you can palpate the coracoid process
Type of Joint for Sternoclavicular
synovial; saddle
moves in all directions like a ball and socket
Type of Joint for Acromioclavicular
Synovial; Planar
Type of Joint for Glenohumeral
Synovial; Ball and Socket (spheroidal)
Ligaments of the GH Joint
Thickenings of the capsule: Superior, Middle, and Inferior GH Ligs (they reinforce the anterior aspect and are shaped like a Z)
Coracoacromial (limits superior excursion of humeral head)
Coracoclavicular (indirectly)
Labrum
Transverse Humeral
Coracohumeral
Type of Joint for Scapulo-Thoracic
Functional; not true articulation
