  Mylohyoid muscle - Wikipedia, the free encyclopedia
The Mylohyoid muscle, flat and triangular, is situated immediately above the anterior belly of the digastric muscle, and forms, with its fellow of the opposite side, a muscular floor for the cavity of the mouth.
It arises from the whole length of the mylohyoid line of the mandible, extending from the symphysis in front to the last molar tooth behind.
The posterior fibers pass medialward and slightly downward, to be inserted into the body of the hyoid bone.

The external surface is marked in the median line by a faint ridge, indicating the symphysis or line of junction of the two pieces of which the bone is composed at an early period of life.
Extending upward and backward on either side from the lower part of the symphysis is the mylohyoid line, which gives origin to the Mylohyoid; 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.
At its junction with the posterior border is the angle of the mandible, which may be either inverted or everted and is marked by rough, oblique ridges on each side, for the attachment of the Masseter laterally, and the Pterygoideus internus medially; the stylomandibular ligament is attached to the angle between these muscles.

From the cricoid cartilage it arises in the interval between the Cricothyreoideus in front, and the articular facet for the inferior cornu of the thyroid cartilage behind.
On the thyroid cartilage it arises from the oblique line on the side of the lamina, from the surface behind this nearly as far as the posterior border and from the inferior cornu.
The mucous coat is continuous with that lining the auditory tubes, the nasal cavities, the mouth, and the larynx.

Extending upward and backward on either side from the lower part of the symphysis is the mylohyoid line, which gives origin to the Mylohyoideus; 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.
The margin of this opening is irregular; it presents in front a prominent ridge, surmounted by a sharp spine, the lingula mandibulæ, which gives attachment to the sphenomandibular ligament; at its lower and back part is a notch from which the mylohyoid groove runs obliquely downward and forward, and lodges the mylohyoid vessels and nerve.

It is crossed in its upper half by a well-marked transverse ridge with a slight downward convexity, and in many cases a vertical median ridge divides it into two lateral halves.
The portion of the vertical ridge above the transverse line is present in a majority of specimens, but the lower portion is evident only in rare cases.
The anterior surface gives insertion to the Geniohyoideus in the greater part of its extent both above and below the transverse ridge; a portion of the origin of the Hyoglossus notches the lateral margin of the Geniohyoideus attachment.

In the posterior mandible, the cortical plate is much thicker labially than lingually such that it is quite common to have an infection break through the lingual aspect of the mandible.
The apecies of the premolars and the incisors all lie above the mylohyoid line therefore infection may commonly spread to the floor of the mouth, raising the tongue as it crosses the midline in the fascial cleft between the mylohyoid and the geniohyoids.
Finally the roots of the third molar are generally at the posterior border of hte mylohyoid and infection can spread in either or both directions.
