1

How many cervical vertebrae are there?

7

2

What is the vertebrae prominens?

C7

3

How do the transverse processes of C3-6 differ from the other C vertebrae?

Broader and cupped to support spinal nerves

4

Where re the prevertebral and paravertebral muscles found?

Prevertebral anteriorly, paravertebrally laterally

5

Describe location of the scalenus anterior

Lateral neck
Anterior tubercles C3-6 -> scalene tubercle of 1st rib

6

What passes between the scalenus anterior and the scalenus mass?

Subclavian vessels and nerves of the brachial plexus

7

What innervates the scalenes?

Ventral rami of C5&6

8

What other lateral muscles are there in the neck?

Scalene mass, splenius muscles, levator scapulae

9

What plexuses do the cervical nerves form?

C1-C4= cervical plexus
C5-T1= brachial plexus

10

Where is the superior cervical ganglion of the sympathetic chain found?

Opposit C2 inbetween scalenus anterior and prevertebral muscles

11

What is the stellate ganglion and where is it found?

Inferior cervical ganglion of sympathetic chain fused with the 1st thoracic ganglion
In front of the neck of the 1st rib

12

How does sympathetic supply get into the head and brain?

Via the sympathetic plexus that travels with the internal and external carotid arteries

13

What are the rami and what does the phrenic nerve supply?

C3, 4&5, supplies diaphragm

14

Where does the carotid artery bifurcate?

At level of C3

15

What are the branches of the external carotid artery?

Some angry lady figured out PMS-
Superior thyroid, ascending pharyngeal, lingual, facial, occipital, posterior auricular, maxillary, superficial temporal

16

What s found in the carotid sheath?

Internal carotid artery, vagus nerve, internal jugular vein

17

Where does the inferior thyroid artery arise from?

From the subclavian artery via the thyrocervical trunk

18

Where does the superior thyroid artery arise from?

Common carotid via the external carotid

19

How is the path of the inferior thyroid vein different from the superior and middle?

By passes internal jugular vein and enters straight into brachiocephalic vein

20

Describe the parathyroid glands

4 the size of a pea
Located close to the posterior surfaces of the lateral lobes of the thyroid gland

21

Where does the omohyoid attach?

Hyoid bone->intermediate tendon->superior border of scapula

22

Name the 2 deep infrahyoid muscles

Thyrohyoid above and sternothyroid below

23

What are the two superficial infrahyoid muscles?

Sternohyoid (medially) omohyoid (laterally)

24

What innervates the infrahyoid muscles

The ansa cervicalis (C1-C3)
Thyrohyoid & geniohyoid are innervated by C1+hypoglossal nerve

25

Action and innervation of trapezius

Spinal accessory
Upper fibres elevate scapula
Middle fibres retract scapula
Lower fibres depress scapula
Rotation of scapula

26

Actions and innervation of sternocleidomastoids?

Spinal accessory nerve
Tilts head to shoulder on same side
Turns face towards opposite side
Draws head forwards

27

Borders of posterior triangle

Trapezius, sternocleidomastoid, clavicle

28

Borders of anterior triangle

midline of neck, sternocleidomastoid and inferior border of mandible
Apex is jugular notch

29

What does the muscular part of the anterior triangle contain?

Infrahyoid muscles and thyroid gland

30

Name the superficial cervical lymph nodes

Occipital, posterior auricular, preauricular, submandibular and submental
Generally found surrounding external jugular vein

31

Name the groups of deep cervical lymph nodes

Surrounding internal carotid
Prelaryngeal
Pretracheal
Paratracheal
Retropharyngeal
