Q

innervation of longus colli

A

O and I:
upper portion extends from anterior surface of vertebral bodies above to transverse processes of vertebrae below

lower portion extends from anterior surfaces of vertebral bodies below to transverse processes of vertebrae above

17
Q

action of longus colli

A

flexes neck and assists in its rotation

upper fibers rotate same side
lower fibers rotate opposite side

18
Q

innervation of longus colli

A

ventral rami - spinal nerves C2-7

19
Q

right brachiocephalic artery

A

bifurcates posterior to SC joint into right subclavian and common carotid artery

20
Q

left aorta

A

common carotid and subclavian artery arise directly from aorta

21
Q

three parts of subclavian artery

A

1 - medial to anterior scalene
2 - behind anterior scalene
3 - lateral to anterior scalene

22
Q

part 1 of subclavian artery

A

vertebral artery
thyrocervical trunk
internal thoracic artery

23
Q

vertebral artery

A

enters transverse cervical foramen of CV6
goes posterior over atlas
pierces AO membrane
ascends through foramen magnum where it fuses with opposite counterpart

24
Q

branches of thyrocervical trunk

A

inferior thyroid artery
transverse cervical artery
suprascapular artery
ascending cervical artery

25
It'S TC-AC
inferior thyroid suprascapular transverse cervical ascending cervical arterial branches of thyrocervical trunk
26
inferior thyroid artery
branches from thyrocervical trunk medially to ascend medial border of anterior scalene passes behind carotid sheath and sympathetic trunk at level of thyroid cartilage branches to pharynx larynx trachea and esophagus glandular branches to inferior thyroid **anastomose with posterior branch of superior thyroid artery
27
transverse cervical artery
branches from thyrocervical trunk laterally crosses posterior triangle by passing deep to trapezius muscle which it supplies
28
suprascapular artery
branches from thyrocervical trunk laterally just inferior to origin of transverse cervical artery crosses posterior triangle inferiorly deep to inferior belly of omohyoid joined by suprascapular nerve as it passes out of posterior triangle laterally to scapular region
29
ascending cervical artery
possible branch of thyrocervical trunk -often from inferior thyroid artery ascends anterior scalene medial to phrenic nerve to provide muscular and spinal branches
30
internal thoracic artery
arises from subclavian opposite thyrocervical trunk descends inferiorly to thorax posterior to sternal end of clavicle and junction of subclavian and internal jugular veins crossed anteriorly by phrenic nerve
31
costocervical trunk
second part of subclavian artery -passes posteriorly from subclavian artery over cupola of lung where it divides into: deep cervical and highest intercostal artery
32
deep cervical artery
branch of costocervical trunk ascends dorsal to brachial plexus between semispinalis cervicis and capitis anastomose with descending branch of occipital artery
33
highest intercostal artery
branch of costocervical trunk descends anterior to head of first rib to provid posterior intercostal artery to first intercostal space and terminates by forming second posterior intercostal artery
34
dorsal scapular artery
part 3 of subclavian artery branching passes dorsally through brachial plexus near middle trunk descends under rhomboids along vertebral border of scapula involved in scapular anastomosis
35
brachiocephalic vein formation
from subclavian and internal jugular veins
36
tributaries to subclavian vein
external jugular, dorsal scapular
37
tributaries to brachiocephalic vein
vertebral and inferior thyroid vein
38
central venous line
utilize subclavian vein parenteral fluids or drugs, cardiac cath, means of measuring central venous pressure stick the axillary vein, needle to subclavian vein
