clavicle

has branches of lateral pectoral nerve
and thoracoacromial artery

also starting point of cephalic vein though arm

Question 8

Deltoid attachments

Answer 8

clavicular-start from lateral one third of clavicle

acromial-start from accordion

spinal part-originates from scapular spine

All end on deltoid tuberosity of humorous

Question 9

deltoid innervation and verts

Answer 9

axillary nerve

c5-6

deltoid actions

Answer 10

clavicular-flex, internally rotatem and adduct arm at shoulder

acromial part-abduct arm

spinal-extend, externally rotate and adduct arm to shoulder

60-90 degrees of abduction-clavicular and spinal parts help with abduction

Answer 11

clavicular part-from medial half of clavicle

sternocostal-from sternum and costal cartilages 1-6

abdominal part-anterior layer of rectus sheath-4th rib from bottom

all insert onto crest of greater tuberosity on humorous

Answer 12

medial and lateral pectroal nerves

c5-t1

Question 13

pec major actions

Answer 13

all-adduct and interally rotate arm at shoulder

claviular and sternocolstal-flex arm at shoulder and assist in respiration when shoulder fixed

Answer 17

originates from 3-5th ribs

inserts in coracoid process

Question 18

thoracoacromial and lateral thoracic arteries

anterior/posterior cicumfle artires and subscapular artery

Question 21

superior thoracic artery

Answer 21

-extends form lateral edge of first rib to medial boarder of muscle (i think pec minor)

Question 22

thoracoacromial and lateral thoracic arteries

Answer 22

-lie under pec minor and start as one branch of axillary

Question 23

anterior/posterior cicumfle artires and subscapular artery

Answer 23

• all start as one

- extends from lateral margin of muscle down to where artery crosses tendon of trees major
