 BASE: Body of mandible and the line joininig
the angle of mandible to mastoid process

3. Facial artery
4. Lingual &
5. Sup. Thyroid artery
 VEIN:
1. Internal jugular
2. External jugular
 Submandibular gland
 Accessory nerve
 Vagus nerve
 Suprahyoid & infrahyoid muscle

7. Posterior Triangle 0f
Neck

8. Boundaries &
Subdivisions
• Boundaries:
• Anteriorly posterior border of the
Sternocleidomastoid
• Posteriorly anterior border of trapezius
• Apex is the meeting point of
sternocleidomastoid and trapezius
• Base is the medial one third of the clavicle
• Roof is skin , superficial fascia and deep
fascia
• Floor is the prevartebral layer of deep
cervical
fascia

10. Submandibular Region
The area between the body of
mandible and the hyoid bones is
known as submandibular region
BOUNDARIES:
 Superiorly mylohyoid muscle ,
inferior border of mandible
 Inferiorly anterior and posterior
belly of digastric
 Laterally deep cervical fascia ,
platysma
 Medially hypoglossus
 Anteriorly submental space
 Posteriorly hyoid bone

11. Contents of
submandibular region
1. Submandibular salivary gland
2. Proximal portion of
Submandibular duct
3. Lingual and hypoglossal nerve
4. Branches of facial artery
paletine, tonsillar glandular
branch

12. Clinicals
1. The most common location for atherosclerotic
plaque formation is at the bifurcation or
branch points of arteries, in the case of
the carotid arteries
2. bruit is a systolic murmur heard only in the
neck arteries
3. Tracheostomy a surgical procedure to create
an opening through the neck into the trachea
4. Carotid sinus syndrome
