digastric muscle

When the digastric muscle contracts, it acts to elevate the hyoid bone.

The term "digastric muscle" refers to this specific muscle.

It is perforated, near its insertion, by the intermediate tendon of the digastric muscle.

Muscles that arise from the arch are those involved with facial expression and the posterior digastric muscle.

Level II contains the upper jugular lymph nodes, which are above the digastric muscle.

It may be united to or replaced by the anterior belly of the digastric muscle; accessory slips to other hyoid muscles are frequent.

The digastricus (digastric muscle) consists of two fleshy bellies united by an intermediate rounded tendon.

The two bellies of the digastric muscle have different embryological origins, and are supplied by different cranial nerves.

The submandibular glands are a pair of glands located beneath the lower jaws, superior to the digastric muscles.

In the neck, the accessory nerve crosses the internal jugular vein around the level of the posterior belly of digastric muscle.

Tensing the stylohyoid muscles and posterior bellies of the pair of digastric muscles also helps.

The mylohyoid muscle is flat and triangular, and is situated immediately above the anterior belly of the digastric muscle.

Lying superior to the digastric muscles, each submandibular gland is divided into superficial and deep lobes, which are separated by the mylohyoid muscle:

The digastric muscle (also digastricus) (named digastric as it has two bellies) is a small muscle located under the jaw.

The stylohyoid muscle is a slender muscle, lying anterior, and superior of the posterior belly of the digastric muscle.

It also innervates the posterior belly of the digastric muscle, the stylohyoid muscle, and the stapedius muscle of the middle ear.

Its boundaries are the Hypoglossal Nerve, and the Anterior and Posterior belly of the Digastric muscle.

Region bound by the digastric muscle superiorly and the hyoid bone (clinical landmark), or the carotid bifurcation (surgical landmark) inferiorly.

The jugulodigastric lymph node is a large node found in the proximity of where the posterior belly of the digastric muscle crosses the internal jugular vein.

The stylohyoid muscle, stapedius and posterior belly of the digastric muscle are also innervated by the facial nerve, but are not considered muscles of facial expression.

The mylohyoid nerve (or nerve to mylohyoid) is a nerve that innervates the mylohyoid muscle and the anterior belly of the digastric muscle.

This process serves for the attachment of the Sternocleidomastoid, Splenius capitis, [(the posterior belly of the digastric muscle)], and Longissimus capitis.

Béclard's triangle: An area whose boundaries are the posterior border of the hyoglossus, the posterior belly of the digastric muscle and the greater horn of the hyoid bone.

This space is bounded behind by the sternocleidomastoid, above by the stylohyoid and the posterior belly of the digastric muscle, and below by the superior belly of the omohyoid.

It is a potential space, and is paired on either side, located on the superficial surface of the mylohyoid muscle between the anterior and posterior bellies of the digastric muscle.
