This space is subdivided into four smaller triangles by the Digastricus above, and the superior belly of the Omohyoideus below.
The nerve then descends obliquely behind the Digastricus and Stylohyoideus to the upper part of the Sternocleidomastoideus;...

  Digastric muscle - Wikipedia, the free encyclopedia
A broad aponeurotic layer is given off from the tendon of the Digastricus on either side, to be attached to the body and greater cornu of the hyoid bone; this is termed the suprahyoid aponeurosis.
The Digastricus divides the anterior triangle of the neck into three smaller triangle
(3) the suprahyoid or submental triangle, bounded laterally by the anterior belly of the Digastricus, medially by the middle line of the neck from the hyoid bone to the symphysis menti, and inferiorly by the body of the hyoid bone.

A broad aponeurotic layer is given off from the tendon of the Digastricus on either side, to be attached to the body and greater cornu of the hyoid bone; this is termed the suprahyoid aponeurosis.
It is perforated, near its insertion, by the tendon of the Digastricus.
—The Mylohyoideus and anterior belly of the Digastricus are supplied by the mylohyoid branch of the inferior alveolar; the Stylohyoideus and posterior belly of the Digastricus, by the facial; the Geniohyoideus, by the hypoglossal.

The "normal", in the anterior belly arises from the fossa digastricus of the manadible, and passes downward, backward and slightly outward to become continuous with the intermediate tendon (46.1% 0f 262 cadavers).
The boundry between the anterior belly of digastricus and the unusual muscle plate is clearly defined.
The anterior belly of digastricus is a branchiomeric muscle derived from the mesoderm associated with the branchial arches.

 Ask E.T.: Mapped pictures: image annotation
Take Henry Gray's "Anatomy of the Human Body" as another case in point.
Notice the different typefaces and colors used to distinguish between various tissues, such as muscle and bone (although they do not seem to be completely consistent in this example), and the hyphenation of the digastricus as it passes beneath the stylo-hyoideus.
Note also the inconsistent type orientation, how some of the vertical muscles are labeled with the text running up-to-down, while others run down-to-up.

The digastricus is composed of a caudal and a rostral portion, each having separate cranial innervation.
The digastricus, which extends from the base of the skull to the caudoventral surface of the mandible, acts to open the lower jaw.
The masseter, temporalis and pterygoid muscles all elevate (close) the lower jaw, while the buccinator tightens the cheek pouch.

digastricus actually starts as two muscles embryologically and they merge into one muscle during development.
there is also a rostral belly of the digastricus which has a separate innervation.
next caudal branch is the inferior alveolar nerve which goes w/inf alv art into mandible, and is sensory to lower lip and to teeth, and then the most caudal is the myelohyoid n which goes to mylohyoideus muscle nd the rostral belly of the digastricus, and is motor to mylohyoideus..

 Stylohyoid muscle
The Stylohyoid muscle is a slender muscle, lying in front of, and above the posterior belly of the Digastricus.
It arises from the back and lateral surface of the styloid process, near the base; and, passing downward and forward, is inserted into the body of the hyoid bone, at its junction with the greater cornu, and just above the Omohyoideus.
Please edit the article if this is the case, and feel free to remove this notice when it is no longer relevant.

It then curves upward over the body of the mandible at the antero-inferior angle of the Masseter; passes forward and upward across the cheek to the angle of the mouth, then ascends along the side of the nose, and ends at the medial commissure of the eye, under the name of the angular artery.
It supplies the surrounding muscles, and anastomoses with the sublingual artery and with the mylohyoid branch of the inferior alveolar; at the symphysis menti it turns upward over the border of the mandible and divides into a superficial and a deep branch.
—At its origin, it is covered by the posterior belly of the Digastricus and the Stylohyoideus, and the hypoglossal nerve winds around it from behind forward; higher up, it crosses the internal carotid artery, the internal jugular vein, and the vagus and accessory nerves.

Strongest muscle of the first arch is the adductor mandibulae which in tetrapods has split into the masseter, temporalis, and pterygoideus.
The myohyoideus, digastricus, and tensor tympani of tetrapods probably arose from the intermandibular of fishes.
In tetrapods, the posterior belly of the digastricus participates in chewing.
