8

The boundaries of the submental triangle...

1) L/R anterior bellies of the digastric muscles
2) the body of the hyoid bone

9

the mylohyoid muscle

10

what are the contents of the submental triangle?

minor vessels and some lymph nodes

11

what is one clinical aspect of the submental triangle?

15

What is one major clinical aspect/consideration with the submandibular trianlge?

use caution when palpating or adjusting with contacts in this area due to the importance of the neurovascualr contents
