These four muscles have different actions, but in general assist in elevating the hyoid bone and widening the esophagus during swallowing.When the two bellies of the digastric contract, they pull upward on the hyoid bone; but if the hyoid is fixed from below, the digastric assists in extreme opening of the mouth such as yawning or taking a large bite of an apple.

The digastric muscle (also digastricus) (named digastric as it has two 'bellies') is a bilaterally paired suprahyoid muscle located under the jaw.Its posterior belly is attached to the mastoid notch of temporal bone, and its anterior belly is attached to the digastric fossa of mandible; the two bellies are united by an intermediate tendon which is held in a loop that attaches to the hyoid bone.
The stylohyoid muscle is one of the suprahyoid muscles. [1] Its originates from the styloid process of the temporal bone ; it inserts onto hyoid bone. It is innervated by a branch of the facial nerve .
The inferior mental spines are the points of origin of the geniohyoid muscle, [2] one of the suprahyoid muscles, and the superior mental spines are the origin of the genioglossus muscle, one of the muscles of the tongue. Mental spines are important landmarks in clinical practice.
Suprahyoid muscles - Digastric (Ant and post belly), mylohyoid, geniohyoid and stylohyoid. Infrahyoid muscles - Omohyoid, sternohyoid, sternothyroid, and thyrohyoid. Nerve supply
Healing can take a few days, so having enough BCAAs to optimize muscle protein synthesis makes your muscles’ active-recovery window more efficient—meaning you recover faster, says Jones.
It is limited to: Lateral (away from the midline), formed by the anterior belly of the digastricus; Medial (towards the midline), formed by the midline of the neck between the mandible and the hyoid bone
