Flashcards in DR - root of neck Deck (35)
1

what features can be seen on the first rib

scalene tubercle
impressions made by subclavian vessels

2

what are the boundaries of the root of the neck

line from the manubrium, along the clavicle to the coracoid process, along the upper border of the scapula to T1

encompasses both the thoracic and axillary inlets

3

where is the right recurrent laryngeal nerve given off

anterior to the first part of the right subclavian artery
it winds under the artery and passes upwards in the groove between the oesophagus and trachea
enters deep to the inferior constrictor of pharynx

4

where is the phrenic nerve

lies behind the prevertebral fascia
passes inferomedially over scalenus anterior

enters the thoracic inlet close to the internal thoracic artery
lies between the subclavian vein and artery

5

what does the external jugular vein drain into

subclavian vein

6

what separates subclavian vein and artery

scalenus anterior

7

what joint does the subclavian artery pass posterior to when entering the neck

sternoclavicular joint

8

when does the subclavian artery become the axillary artery

outer border of the first rib
(posterior to scalenus anterior)

9

what structures cross the right subclavian artery

vagus nerve, vertebral and internal jugular veins

10

what structures cross the left subclavian vein

left phrenic nerve and terminal part of the thoracic duct

11

what are the branches of the first part of subclavian

vertebral artery, thyrocervical trunk, internal thoracic artery

12

describe the course of the vertebral artery

arises from the first part of subclavian

passes posteriorly through a deficit in prevertebral fascia to enter the foramina transversaria of 6th to 1st cervical vertebrae

13

what artery does the thoracic duct lie anteriorly to on the left side

vertebral artery

14

what are the branches of the thyrocervical trunk

inferior thyroid, suprascapular and transverse cervical

15

describe the inferior thyroid artery

posterior to the neurovascular triangle, passes upwards to the thyroid gland
gives off an inferior laryngeal branch
closely related to the recurrent laryngeal nerve
supplies the thyroid gland

16

what is the function of the suprascapular artery

arterial anastomosis around the scapula

provides a subsidiary route for blood to pass from the subclavian artery to axillary artery when either artery is blocked

17

describe the transverse cervical artery

crosses the posterior triangle towards trapezius
takes part in anastomosis around the scapula

18

what is the internal thoracic artery a branch of

the third branch of the first part of subclavian

19

what are the branches of the costocervical trunk

deep cervical and supreme intercostal branches

supplies the upper to intercostal spaces and apex of the lungs

20

where can the trunks of the brachial plexus be seen

behind scalenus anterior, they lie of scalenus medius deep to prevertebral fascia

21

where is the left vagus nerve

lies between the left common carotid artery and the left subclavian artery, behind the subclavian vein

22

where is the left reccurent laryngeal nerve

passes under the aorta and ligamentum arteriosum

23

what are the coverings of the apex of the lung

cervical pleura and suprapleural membrane

24

where is the summit of the lung apex

2.5 cm above the medial third of the clavicle

25

what is the function of the suprapleural membrane

gives rigidity to the thoracic inlet in order to prevent distortion during respiratory changes of intra thoracic pressure

26

where is the cervical sympathetic trunk

posterior to the carotid sheath, medial to the vagus and anterior to the prevertebral fascia

27

where is the superior cervical ganglion

level of the 2nd and 3rd cervical vertebrae

28

where is the middle cervical ganglion

anterior aspect of c6 transverse process

29

what is the stellate ganglion

the inferior cervical ganglion and the first thoracic ganglion joined together

30

where is the stellate ganglion

anterior to the neck of the first rib

31

what side is the thoracic duct on

left

32

describe the course of the thoracic duct

ascends from the thorax, arches posterior to the carotid sheath and then passes anterior to the subclavian artery to meet the junction of the internal jugular and subclavian veins

33

where does the oesophagus start

C6

34

what nerve carries the skeletal muscle motor innervation of the oesophagus

vagus

35

what side does the oesophagus lie on

left side of the medial plane
