Neck part 2 Flashcards
What are the borders of the anterior cervical region
median line of neck
anterior border of scm

jugular notch
what are the subdivision of the anterior region
1 submental
2 submandibular
3 carotid
4 muscular
how are the subdivsion created in the anterior region
by the digastric m and the omohyoid m.
what is in the submental triangle of the anterior region
HDMA ( cord )
- hyoid b.
- digastric m
- mylohyoid m
- AJV
what creates the anterior jugular vein
these would be the superficial vv.
- *submental v.
- *inferior hyoid v.
- *inferior labail v.
- this drains into the EVJ or the SC
