what ligament forms the roof of the the humeral head

the coracoacromial ligament - coracoid and the acromion helps limit the superior translation of the humerous and seperation of the the AC joint

what are the two part of the coracoclavicular ligament

the trapezoid and the conoid

what is the purpose of the coracoclavicular ligament

primary support for the AC joint - limits anterior translation of the humeral head

what is the coracohumeral ligament

between the coracoid and splits to attach to the lessar and greater tub of the humerus limits inferior translation of the humerus

what is the rotator interval

The supraspinatus tendon forms the superior boundary, the subscapularis tendon forms the inferior boundary in the anterior-superior surface of the GH joint

what are the two bursa of the shoulder

subacromial bursa and subscapular bursa

where is the subacromial bursa

over the supra spinatus tendon

where is the subscapular bursa

lies beneath the subscapular muscle and over the anterior joint capsule

what are the three joint of the elb

HR HU proximal - RU

RH-joint motions

flexion extension pronation and supination

RH-joint OPP

full extension and supination

RH-joint CPP

90 flexion 5 supination

what is the capsular pattern of the RH-joint

flexion > ext

the RH-joint in formed by what

the humerus and capitulumn of the radius

what forms the HU-joint

trochlea and the humerus

what are the motions seen at the HU-joint

flexion and ext

what is the OPP for the HU-joint

70-deg of flexion 10-deg of supination

what is the CPP for the HU-joint

extension

what is the capsular pattern of the HU joint

flexion > extension
