2- Fascia of the Neck
Objectives
By the end of this lab students are expected to be able to
1. Identify different layers of cervical fascia and the compartments made by them.
2. Locate the retropharyngeal and parapharyngeal spaces
3. Describe superficial structures of the neck
Lab check list
 Superficial Fascia
 Platysma
 External Jugular Vein
 Anterior Jugular Vein
 Cutaneous nerves
1. Greater occipital nerve
2. Lesser occipital nerve
3. Great auricular nerve
4. Transverse cutaneous nerve
5. Supraclavicular nerves
 Deep fascia of the neck
1. Investing layer of deep cervical fascia (Rule of 2)
2. Pretracheal Layer
3. Prevertebral Layer (strong)
 Retropharyngeal space
 Parapharyngeal space
4. Carotid Sheath
5. Axillary Sheath

Nice to know: Rule of 2: investing layer of deep cervical fascia
1. Encloses 2 muscles, trapezius and sternocleidomastoid.
2. Roofs 2 triangles, anterior and posterior triangles.
3. Enclose 2 glands, submandibular and parotid.
4. Enclose 2 spaces, suprasternal and supraclavicular.
5. Forms 2 fascial slings (pulleys), for inferior belly of omohyoid and intermediate tendon of
digastric muscle.
Homework:
How the anatomy of the retropharyngeal and parapharyngeal spaces is related to dental work?
