20
Q

What does the compartment of the neck communicate with inferiorly?

A

The mediastinum

21
Q

Which fascia surround the visceral compartment of the neck?

A

Pretracheal

Buccopharyngeal

22
Q

Between which fascia do the anterior vertebral muscle lie?

A

The investing fascia and pretracheal fascia

23
Q

How many branches does the external carotid have?

A

6 before it splits into 2 terminal branches

23
Q

Which nerves run in the anterior triangle?

A

CN9,10,11 and 12

24
Q

What is the name of the part of the thyroid that connects the two lateral lobes?

A

The isthmus

26
Q

What are the anterior borders of the neck?

A

Lower border of the mandible

Manubrium

27
Q

Which muscles lies in the superficial layer of the neck?

A

The platysma

29
Q

What are the branches of the external carotid artery?

A

Some Anatomists Like Fucking, Others Prefer S&M

Superior thyroid artery (front)

Ascending pharyngeal artery (deep)

Lingual (front)

Facial (front)

Occipital (back)

Posterior auricular (back)

Superficial temporal (terminal)

Maxillary (terminal)

30
Q

How do you differentiate CNXI from CN9 and CN10 in the neck?

A

It heads posteriorly under SCM into the posterior triangle

31
Q

In which trianlge does the internal jugular vein run in?

A

Anterior

32
Q

Do all the nerve of the anterior triangle enter via the same foramen?

A

No, the hypoglossal enters via the hypoglossal canal while the other via the jugular foramen

33
Q

What are the implication of the pretracheal fascia being connected to the hyoid bone?

A

It rises on swallowing therefore anything structures within it will also rise

34
Q

How do you differentiate the vagus from the CN9 and CN11 in the neck?

A

In goes straight down

35
Q

At what level does the common carotid bificate?
