Flashcards in Lecture 4 Vasculature of Back Shoulder Breast Deck (46):
1

back is blank supplied because arteries supply regular intervals in a pattern along the entire vertebral column

segmentally

2

longitudinal arteries

vertebral ascending cervical, vertebral artery

3

blank back muscles get blood from unnamed arteries

intrinsic

4

blank back muscles get blood from additional arteries

extrinsic

5

most superior artery to the back

occipital artery

6

occipital artery supplies blank and posterior skin of the head

suboccipital triangle

7

blood supply to upper third of spinal cord

1 anterior spinal artery, 2 posterior spinal arteries

8

blank parts of the spinal cord are well supplied

cervical/lumbar enlargement

9

spinal cord is drained by

3 anterior spinal veins, 3 posterior spinal veins

10

blood supply of back outside of spinal cord is blank

segmental

11

boundaries of lateral cervical region

superior border of trap, clavicle, scm, prevertebral fascia (floor), investing deep fascia (roof)

12

SCM

sternum/clavicle, mastoid process, neck flexion/protect carotid/jugular/rotate head

13

innervation of scm and trap

spinal accessory

14

posterior belly of omohyoid

scapula, hyoid, stabilize hyoid

15

subclavius

hold clavicle against ribcage and protect subclavian vein and artery

16

scalenes

TP C2-C7, 1st/2nd rib, raise ribs/lateral neck flexion

17

gap between anterior and middle scalene

interscalene triangle

18

external jugular vein empties into

subclavian

19

subclavian vein passes blank the anterior scalene and gets blood from entire upper limb

in front of

20

subclavian artery passes blank the anterior scalene so it is better protected than vein

behind

21

short branch off subclavian

thyrocervical trunk

22

branches of thyrocervical trunk

cervicodorsal trunk, suprascapular

23

two branches of cervicodorsal trunk (transverse cervical)

superficial cervical a, dorsal scapular a.

24

superficial cervical a supplies

trap

25

dorsal scapular supplies

levator scap/rhomboids

26

continuation of subclavian a and changes name at

axillary a, first rib

27

when axillary a enters arm it becomes

brachial a

28

superior thoracic, thoracoacromial, lateral thoracic, anterior humeral circumflex, posterior humeral circumflex, subscapular are all branches off

axillary a

29

superior thoracic suppplies

1/2 intercostal space

30

thoracoacromial branches (CAPD)

clavicular, acromial, pectoral, deltoid

31

lateral thoracic supplies

pectoralis major/minor

32

posterior humeral circumflex supplies

through quadrangular space to deltoid, terest major/minor, long head of triceps

33

subscapular artery supplies and is the most important/largest axillary branch and branches into

circumflex scapular, thoracodorsal

34

thoracodorsal a supplies

lat dorsi

35

arrangement of multiple routes of blood in anastomesis is blank circulation

collateral

36

drains arm, forearm and hand

axillary vein

37

axillary vein becomes blank vein at first rib

subclavian

38

important tributary of axillary vein

cephalic vein

39

structures holding fat and gland tissue in place and attaches it to dermis of overlying skin in breasts

susepensory ligaments

40

15-20 lobes of glandular tissue

mammary glands

41

each lobe of glandular tissue is drained by

lactiferous duct

42

lactiferous duct leads to blank where milk accrues before release

lactiferous sinus

43

blood supply of breast

lateral thoracic, thoracoacromial, internal thoracic, posterior intercostal

44

blood drainage of breast

mostly axillary vein

45

primary lymph drainage of breast

axillary lymph nodes

46

responsible for breasts enlarging during pregnancy and nursing and is a site of fibrocystic disease but not cancer

axillary tail
