Question 7

What attaches to the anterior and medial surface of clavicle?

Answer 7

M. pectoralis major: (also from sternum)

Question 8

Which points does pectoralis major attach to and what does it do?

Answer 8

anterior and medial surface of clavicle, to humerus, Lateral lip of the bicipital groove
-adduction, medial rotation and flexion of arm

Question 9

Answer 9

M. sternohyoid

Question 10

Sternohyoid runs from the posterior and medial surface of clavicle to where? What does it do?

Answer 10

Answer 11

Conoid ligament

Question 12

Answer 13

M.Subclavius

Question 14

What runs from the spine (also to scapula, superior nuchal line) to the Lateral and posterior surface of the clavicle?

Answer 14

M. trapezius:

Question 15

M. trapezius is responsible of..

Answer 15

the elevation, adduction, depression and rotation of scapula

Question 16

Answer 16

M. sternocleidomastoid

head rotation and flexion

Question 17

M. deltoid runs from the Lateral and anterior surface of clavicle (also from scapular) to where? What does it do?

Answer 17

to humerus, deltoid tuberosity

flexion, extension, rotation, abduction of arm

Question 18

Variation of clavicle is shape and size; appearance of costal tuberosity, position of nutrient foramen, shape of acromion. True or false
