Question | Answer |
Shoulder/Pectoral Girdle | part of appendicular skeleton that attaches to upper limbs to trunk; each consists of clavicle and scapula |
Clavicle (collarbone) | sternal end articulates medially w/ sternum’s manubrium; acromial end articulates laterally w/ scapula’s acromion; acts as brace to hold shoulder in lateral position. If broken, shoulder caves medially |
Scapula (shoulder blade) | has acromion, spine, coracoid process, glenoid cavity/fossa |
Acromion | lateral projection on scapula; forms tip of shoulder, articulates with acromial end of clavicle |
Spine (of scapula) | ridge on posterior scapula; skeletal muscle above is supraspinatus; skeletal muscle below is infraspinatus |
Coracoid process | projection to which one fo the tendons of the biceps brachii attaches |
Glenoid cavity/fossa | very shallow socket w/ which head of humerus articulates forming essence of shoulder joint. b/c of shallowness and flexible ligaments, shoulder joint very mobile but prone to dislocation. |
