Appendicular Skeleton Flashcards
the pectoral girdle consists of
clavicle & scapula
two ends of the clavicle
acromial & sternal ends
the acromial end of the clavicle is _______ to the rest of the bone, while the sternal end is ______
lateral; medial
bone marking on the inferior side of the clavicle’s acromial end
conoid tubercle
the ‘point’ of the clavicle’s acromial end points
anteriorally
3 steps to determine if a clavicle is right or left
1) the flatter acromial end is lateral, the fatter sternal end is medial
2) the conoid tubercle is on the inferior side
3) the ‘point’ of the acromial end faces anteriorally
