BIOL 240 Lecture Notes - Lecture 11: Shoulder Girdle, Appendicular Skeleton, Axial Skeleton
Document Summary
Attachment for muscles: one muscle attached there to help turn our necks. The only structure articulating into the axial skeleton. Antebrachium= fore arm: ulna, medial bone in anatomical position, radius. Hand: carpals, metacarpal, bones in palm, phalanges, fingers. Many structures of the humerus provide sites for muscle attachment. Other structures of the humerus provide articulation sites for other bones. Radius and ulna connected by interosseous membrane: considered a joint. Only the radius is articulating with the carpals, never the ulna. Phalanges: 14 phalanges, 3 bones on each finger except for the thumb, where there are 2, thumb = pollex, lateral to medial 1 to 5, thumb is i and pinky is iv. Scaphoid carpal is articulating with the radius. Sacrum and os coxae: os coxae/hipbone = ilium, ischium, + pubis. In pelvis, we have two hip bones right and left: each hipbone consists of 3 different bone.
