Humeral Joint m/lig/tendons Flashcards
synsarcosis
arrangement of muscles without forming conventional articulation between scapula-humerus and around the body
humeral joint
need hyaline cartilage and synovial fluid to be synovial joint
humeral ligament
prevents biceps tendon from moving
glenohumeral ligament
used as reinforcemnt in the joint
biceps tendon
emerges from intertubercular groove
deltoideus scapular
O: spine of scapula
I: deltoid tuberisity of humerus
A: flex humeral joint
deltoideus acromial
O: acromion
I: deltoid tuberosity of humerus
A: flex humeral joint
supraspinatus
O: supraspinous fossa
I: greater tubercle of humerus
A: stabilize humeral laterally, extend humeral joint
infraspinatous
O: infraspinous fossa
I: greater tubercle
A: stabilize humeral joint laterally
tendon of infraspinatus
one of strongest tendons in humeral joint
infraspinatus bursa
sac full of friction that reduces friction in humeral joint
teres minor
O: caudal border of scapula
I: teres minor tuberosity
A: flex humeral joint
subscapularis
O: subscapular fossa
I: lesser tubercle
A: medially stabilize humeral joint, keeps joint in position
teres major
O: caudual border of scapula
I: teres major tuberosity
A: flex humeral joint
coracobrachialis
O: coracoid process
I: crest of lesser tubercle
A: medially stabilize humeral joint
very small
