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
