ligaments

what kind of bone is the metatarsal

long bone

medial end of clavicle articulates with

manubrium first rib

how are the metatarsals named

numbered 1-5 beginning with the hallux (great toe)

how are the metacarpals and phalanges named

numbered 1-5 beginning with the pollex (thumb)

the metacarpals form the

palm

proximal middle distal

except for the hallux each toe has 3 phalanges, what are they

proximal middle distal

radius and ulna articulate with each other at the

proximal and distal radioulnar joints

left and right pubic bones are joined by fibrocartilage at the midline, where they connect is called the

pubic symphysis

the head of the radius articulates with the

radial notch of the ulna

contributes heavily to the wrist joint

radius

the antebrachium is formed by the

radius ulna

the humerus articulates with the ____ and ____ at the elbow

radius ulna

the humerus articulates with the _____ at the shoulder

scapula

scapula's 3 borders

superior medial (vertebral) lateral (axillary)

important functions of the foot

support body weight lever to propel body segmentation makes it pliable

talus

body weight is primarily borne by the

talus calcaneus

foot is composed of
