A

The cervical sympathetic trunk

5
Q

List the tissue spaces of the neck

A

The most important clinically are the prevertebral, retropharyngeal, parapharyngeal, and submandibular spaces

6
Q

Where is the prevertebral space? What is significant about this area?

A

Behind the prevertebral fascia. If the fascia remains intact this space has no escape

7
Q

What lies immediately in front of the prevertebral fascia?

A

A space from the base of the skull to the diaphragm

8
Q

Where is the cervical sympathetic trunk found?

A

Between the prevertebral fascia and the carotid sheath.

9
Q

What is the space from the base of the skull to the diaphragm divided into?

A

The superior aspect is the retropharyngeal space, which is continuous laterally with the parapharyngeal space, and continuous anteriorly into the submandibular space

10
Q
