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
Q

It’S TC-AC

A

inferior thyroid
suprascapular
transverse cervical
ascending cervical

arterial branches of thyrocervical trunk

26
Q

inferior thyroid artery

A

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
Q

transverse cervical artery

A

branches from thyrocervical trunk laterally

crosses posterior triangle by passing deep to trapezius muscle which it supplies

28
Q

suprascapular artery

A

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
Q

ascending cervical artery

A

possible branch of thyrocervical trunk
-often from inferior thyroid artery

ascends anterior scalene medial to phrenic nerve to provide muscular and spinal branches

30
Q

internal thoracic artery

A

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
Q

costocervical trunk

A

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
Q

deep cervical artery

A

branch of costocervical trunk
ascends dorsal to brachial plexus between semispinalis cervicis and capitis

anastomose with descending branch of occipital artery

33
Q

highest intercostal artery

A

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
Q

dorsal scapular artery

A

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
Q

brachiocephalic vein formation

A

from subclavian and internal jugular veins

36
Q

tributaries to subclavian vein

A

external jugular, dorsal scapular

37
Q

tributaries to brachiocephalic vein

A

vertebral and inferior thyroid vein

38
Q

central venous line

A

utilize subclavian vein

parenteral fluids or drugs, cardiac cath, means of measuring central venous pressure

stick the axillary vein, needle to subclavian vein
