ligaments of shoulder girdle Flashcards
(15 cards)
what is the function of the acromioclavicular ligament
stabilize acromioclavicular joint
what is the attachment for acromioclavicular ligament
from superior aspect of acromial end of the clavicle to the adjacent acromion
what is the function of the coracoclavicular ligament
stabilize acromioclavicular joint, limit medial displacement, protraction, and elevation
what are the attachments for trapezoid and conoid of the coracoclavicular ligament
- trapezoid: coracoid process to trapezoid line of clavicle
- coracoid process to conoid tubercle of clavicle
what is the function of the coracoacromial ligament
prevents superior displacement of the humeral head by forming the coracoacromial arch
what is the attachment for coracoacromial ligament
lateral border of coracoid process to acromion adjacent to clavicular articulation
what is the function of coracohumeral ligament?
reinforces superoanterior aspects of joint capsule
what are the attachments for coracohumeral ligament
base of coracoid process to anterior aspect greater tubercle
what is the function of costoclavicular ligament
stabilize sternoclavicular joint, limiting elevation of the clavicle
what are the attachments for costoclavicular ligament
superior aspect of cartilage of first rib to undersurface of the clavicle
what is the function of superior transverse scapular ligament
closes off the suprascapular notch
what are the attachments for superior transverse scapular ligament
base of coracoid process to the medial edge of scapular notch
what are the attachments for glenoid capsule
circumference of glenoid cavity to anatomical neck of humerus
what is the attachments of the glenohumeral ligaments (superior, middle, and inferior)
upper part of medial margin of glenoid cavity to lesser tubercle and anatomical neck
what is the functional of the interclavicular ligament
minimum help, but can assist in resisting depression of the clavicle
