Q

course of vertebral artery

A

branches from prescalaene part of subclavian
ascends as cervical part into foramen transversarium where it becomes the vertebral part and ascends C1-6
exits foramen transversarium into foramen magnum where it becomes the basilar artery - the R and L basilar join and contribute to the circle of Willis

Q

what are the branches of the thyrocervical trunk

A

ITS
inferior thyroid
transverse cervical
suprascapular

17
Q

what is the largest and primary visceral artery of the neck

A

inferior thyroid branch of thyrocervical trunk

18
Q

what does the inferior thyroid artery supply

A

thyroid gland
larynx
oesophagus
parathyroid
trachea
adjacent muscles

19
Q

what branches off the inferior thyroid artery

A

ascending cervical artery

20
Q

what does the ascending cervical artery supply

A

prevertebral muscles and spinal cord

21
Q

what are the branches of the transverse cervical branch of the thyrocervical trunk

A

superficial branch - trapezius
deep branch - rhomboids and scapula

22
Q

what does the suprascapular branch of thyrocervical trunk supply

A

supraspinatus fossa

23
Q

what is the course of the internal thoracic trunk of subclavian artery and what it supplies

A

descends into the thoracic cavity to 6th intercostal space and becomes intercostal arteries which supplies the intercostal spaces

24
Q

what are the 2 branches of the costocervical trunk of subclavian and what do they supply

A

supreme intercostal artery which becomes the posterior intercostal artery which supplies rib 1 and 1-2 intercostal spaces

deep cervical artery which supplies the deep cervical muscles
- this links with the occipital artery

25
Q

what is the only contributor to the subclavian vein

A

EJV and its branches

26
Q

EJV branches close to subclavian

A

anterior JV
suprascapular
transverse cervical

27
Q

anterior prevertebral muscles

A

anterior scalene
longus coli
longus capitis
rectus capitis anterior

28
Q

lateral prevertebral muscles

A

posterior and middle scalene (scalene mass)
rectus capitis lateralis
splenius capitis
levator capitis

29
Q

main action of all prevertebral muscles bar levator scapula

A

flex and rotate head and neck

30
Q

action of levator scapula

A

elevates and rotates scapula

31
Q

rotation of head

A

done at atlantoaxial joint

32
Q

flexion of neck

A

anterior / lateral bending of cervical vertebrae

33
Q

flexion of head

A

bending head relative to vertebral column at atlantooccipital joint
