1

describe the Superficial fascia Superficial to deep

Skin
subcutaneus fat
Platysma (facial nerve)

2

2. Deep compartments of Neck (What does each compartment contain?)

Vertebral - vertebra and Musculature
visceral - trachea, osophagus, thyroid
vascular - Vagus, common carotid and the internal jugular

3

Borders of the anterior triangle

Midline
Ramus of the mandible
Anterior border of the sternocleidomastoid

4

Structures at the levels of the neck

C1. open mouth
C2 superior cervical ganglion
C3 Hyoid
C4 biforcation carotid and thyroid cartilage
C6 Cricoid cartilage, middle cervical ganglion
C7 inferior cervical ganglion

5

Contents of the anterior triangle

Muscles:
hyoid bone
Carotids and internal jugular vein

6

Which deep muscles are in the following groups?

Suprahyoid 
Mylohyoid, Geniohyoid, stylohyoid, , Digastric

Infrahyoid 
Thyroihyoid, Omohyoid, Sternohyoid, Sternothyroid

TOSS My Gravy Spoon Darling

7

What about the innervation of the suprahyoid

Innervation
 Anterior: Myolohyoid and the anterior belly of digastric via V3

 Posterior: Stylohyoid and the posterior belly of digastric via Facial Nerve

EXCEPTION: Geniohyoid  C1 fibres via the Hypoglossal Nerve

8

What about the innervation of the infrahyoid

Innervation of

Omohyoid, Sternohyoid and the sternohyoid via Ansa cervicalis


EXCEPTION: Thyrohyoid muscle  C1 fibres via the Hypoglossal Nerve

9

Borders of the posterior triangle

Clavicle

The posterior border of the sternocleidomastoid

the anterior border of the trapezius

10

contents of the posterior triangle

SUbclavian artery and vein
external jugular vein
Accessory nerve
brachial plexus
Phrenic nerve
Vagus nerve

11

Anatomical position of the scalene muscles from anterior to posterior

carotid sheath with its contents
Subclavian vein
Phrenic nerve
Scalenus anterior
brachial plexus roots and Subclavian artery
Scalenus medius

12

Where does the spinal accessory nerve exit, innervate and how would you test it?

exist the skull at the jugular foramen
-> innervates sternocleidomastoid and the trapezius

raise shoulders

13

Where does the vagus nerve exit, innervate and how would you test it?

Jugular foramen
innervates the larynx, Heart, lungs and the GI tract

14

Where does the phrenic nerve exit, innervate and how would you test it?

C3,C4,C5 innervate the diaphragm

lies anterior scalenus muscles
enters thorax between the subclavian artery and vein

15

What 2 arteries supply the thyroid gland

Superior thyroid artery - external carotid
inferior thyroid artery - subclavian artery
it also innervates the superior oesophagus and the trachea

16

What arteries drain the thyroid gland

Superior and middle drain into the jugular vein

inferior thyroid vein drains into the brachicephalic trunk

17

Where is the brachial plexus in relation to the scalene muscles

between Scalenus Anterior and Scalenus Medius

18

PLacement, use and complications of a central line

placed into thte neck
thorax
groin

19

What are the branches of the subclavian artery

vertebral artery
internal thoracic
inferior thyroid artery

Complication
nerve damage
air embolism
thrombosis
infection
