Flashcards in Neck and face Deck (32):
1

Recall the functional compartments of the neck

Anterior visceral
Posterior vertebral
2 Lateral neurovascular compartments

2

At what vertebral layer is the open mouth?

C1

3

At what vertebral layer is the body of the hyoid?

C3

4

At what vertebral layer is the cricoid cartilage?

C6

5

Define the boundaries of the anterior and posterior triangles of the neck

Anterior = Anterior border of SCM, inferior border of mandible
Posterior = posterior border of SCM, anterior border of trapezius, middle 1/3 of clavicle

6

Recall the suprahyoid muscles

Stylohyoid
Digastric
Mylohyoid
Geniohyoid

7

Recall the infrahyoid muscles

Omohyoid
Sternohyoid
Thyrohyoid
Sternohyoid

8

Recall the origins of each belly of the digastric

Anterior belly = lower inner mandible
Posterior belly = mastoid notch on temporal bone

9

Recall the innervation of each belly of the digastric

Anterior = CNV2
Posterior = CNVII

10

What is the function of mylohyoid?

Support and elevation of floor of mouth

11

Recall the insertion of omohyoid

Superior border of scapula

12

Which muscles are also referred to as the "strap" muscles?

Infrahyoid

13

Recall the pathway of the right subclavian artery

Branches from BCT posterior to SC joint
Arches superolaterally, crossing ant. scalene
Crosses rib 1 --> axillary artery

14

Recall the pathway of the left subclavian artery

Lies posterior to left common carotid + lateral to trachea
Ascend and arches laterally

15

Recall 5 possible complications of central venous line insertion

Pneumothorax
Nerve damage
Embolism
Thrombosis
Infection

16

Recall the course of the vertebral arteries

Medial to anterior scalene
Enters transverse foramen of C6
Enters skull via foramen magnum

17

Describe the location of the scalene muscles in coronary section

Lateral to vertebrae
Posterior, middle and anterior bellies
Within buccopharyngeal fascia

18

Recall the landmark of insertion of a central venous line

palpate common carotid, insert needle into the IJV just lateral to it

19

Recall the 3 main branches of the subclavian

Vertebral artery
Thyrocervical trunk
Internal thoracic

20

Recall the lymphatic drainage of the face and scalp

= SUPERFICIAL nodes
5 groups:
Occipital
Mastoid
(O+M --> IJV)
Parotid
Submandibular
Submental
(P, S + S --> deep CERVICAL nodes --> anterior jugular vein)

21

Where are the superficial and deep cervical nodes located?

Superficial = EJV on surface of SCM
Deep = IJV

22

Recall the drainage of lymph from the deep cervical nodes

Deep cervical nodes --> right and left jugular trunks --> right lymphatic duct/ thoracic duct

23

How can cervical lymphadenopathy indicate disease? (2 ways)

Soft/ tender = infection
Firm/ large volume= lymphoma

24

Recall the path of the phrenic nerves

1. Upper lateral border of anterior scalene --> cross down over anterior surface
2. Passes between SCVs to enter thorax:
Right = close to IVC
Left = pierces diaphragm

25

Recall the course of the spinal accessory nerve in the neck

Crosses IJV at level of posterior belly of digastric, pierces SCM and --> trapezius

26

What is the platysma?

Thin sheet of muscle overlaying the anterior triangle of the neck

27

Recall the 5 main branches of the external carotid artery

Occipital
Facial
Posterior auricular
Maxillary
Transverse facial

28

What lies within the carotid sheath?

IJV
Common carotid artery
Vagus nerve

29

Which membrane is ruptured in an emergency to produce a temporary airway?

The membrane between the thyroid and cricoid cartilages

30

Which muscles runs from the midpoint of the inferior maxilla to the hyoid?

Geniohyoid

31

Recall the key superficial veins draining the face and scalp

Posterior auricular and EJV, transverse cervical and retromandibular --> main EJV
There is also an anterior jugular vein

32

Recall 4 of the nerves supplying the neck

Lesser occipital
Great auricular
Accessory
Supraclavicular
