Ligaments of the Pectoral Girdle Flashcards
(21 cards)
function of the CORACOCLAVICULAR LIGAMENTS (and name them)
(TRAPEZOID AND CONOID) stabilizes AC joint by limiting medial displacement, protraction & elevation of the clavicle
attachment of TRAPEZOID LIGAMENT
from coracoid process to trapezoid line of the clavicle
attachment of the CONOID LIGAMENT
from the coracoid process to the conoid tubercle of clavicle
function of the ACROMIOCLAVICULAR LIGAMENT
stabilizes AC joint
attachments of the ACROMIOCLAVICULAR LIGAMENT
from the superior aspect of the acromial end of the clavicle to acromion
function of the CORACOACROMIAL LIGAMENT
prevents superior displacement of the humeral head by forming the coracoacromial arch
attachments of the CORACOACROMIAL LIGAMENT
from lateral border of coracoid process to acromion adjacent to clavicular articulation
function of the CORACOHUMERAL LIGAMENT
reinforces superioanterior aspects of joint capsule
attachments of CORACOHUMERAL LIGAMENT
from base of coracoid process to anterior aspect of greater tubercle
function of the COSTOCLAVICULAR LIGAMENT
stabilizes SC joint, limiting elevation of the clavicle
attachments of COSTOCLAVICULAR JOINT
from superior aspect of cartilage of first rib to undersurface of clavicle
functions of the SUPERIOR TRANSVERSE SCAPULAR LIGAMENT
closes off supra scapular notch
attachments of SUPERIOR TRANSVERSE SCAPULAR LIGAMENT
from the base of the coracoid process to the medial edge of the scapular notch
what are SYNOVIAL JOINTS
joints that have:
- synovial fluid
- joint capsule
- articular cartilage
- ligaments that connect bone to bone
- are DIARTHROSIS joints (freely-movable joints in the body)
name the SYNOVIAL JOINTS in the body
- Acromioclavicular joint
- Sternoclavicular joint
- Glenohumeral joint
synovial classification of ACROMIOCLAVICULAR JOINT
plane / gliding joint
what ligaments make up the ACROMIOCLAVICULAR JOINT and what do they do
- Acromioclavicular ligament
- Coracoclavicular ligaments (trapezoid and conoid): main stabilizers of AC joint : prevent superior migration of clavicle
what ligaments make up the STERNOCLAVICULAR JOINT and what do they do
(1) Sternoclavicular ligament (anterior and posterior) : limits anterior and posterior translation of clavicle
(2) Costoclavicular ligament : limit elevation of clavicle
(3) Interclavicular ligament : limits downward movement of clavicle
synovial classification of GLENOHUMERAL JOINT
ball-and-socket joint
what are PSEUDO JOINTS
joints that do not have synovial fluid, joint capsule, ligaments, any real surfaces, or cartilage
classification of SCAPULOTHORACIC JOINT
pseudo joint
