Mylohyoid line
Encyclopedia
Extending upward and backward on either side from the lower part of the symphysis
of the mandible is the mylohyoid line, which is the origin of the mylohyoid muscle
; the posterior part of this line, near the alveolar margin
, gives attachment to a small part of the Constrictor pharyngis superior, and to the pterygomandibular raphé

Pterygomandibular raphe
The pterygomandibular raphe is a tendinous band of the buccopharyngeal fascia, attached by one extremity to the hamulus of the medial pterygoid plate, and by the other to the posterior end of the mylohyoid line of the mandible.* Its medial surface is covered by the mucous membrane of the mouth.*...
