3

pectoral girdle consists of

scapulae
clavicles

4

each clavicle articulates with the _______

manubrium of the sternum

5

what is the only direct connect between pectoral girdle and the axial skeleton

clavicle-manubrium of the sternum

6

what doe the scapula and clavicle do

position the shoulder
help move the upper limb
provide a base for muscle attachemtn

7

where muscles attach to the scapula/clavicle

marks are left in the form of bony ridges and flanges

8

scapula articulates with

humerus and clavicle

9

scapula serves as attachment site for

shoulder, back, and arm muscles

10

the clavicle does this

holds the shoulder away from the body, permitting free movement of the arm

16

the upper limb is attached ______ and functions in ________

loosely
grasping and manipulation

17

the arm bone is the

deltoid tuberosity
epicondyles

20

the forearm consists

radius and ulna

21

ulna and radius articulate with

each other
humerus
wrist bones

22

wrist ligamenst attach to the

styloid processes of the radius and ulna

23

wrist has how many bones

8 carpal bones

24

carpal bones

27

the distal row of the carpal bones articulates with

5 metacarpal bones

28

the spaces between the metacarpals are occupied with

soft tissue

29

the phalanges are the

digit bones
