mylohyoid muscle

The mylohyoid muscle is derived from the first pharyngeal arch.

The mylohyoid muscle runs under it.

Each submandibular gland is divided into superficial and deep lobes, which are separated by the mylohyoid muscle.

Mandibular tori are usually present near the premolars and above the location of the mylohyoid muscle's attachment to the mandible.

The mylohyoid muscle is a muscle running from the mandible to the hyoid bone, forming the floor of the oral cavity.

The sublingual space communicates posteriorly around the posterior free border of the mylohyoid muscle with the submandibular space.

The Geniohyoid muscle is a narrow muscle situated superior to the medial border of the mylohyoid muscle.

It is a potential space located below the mouth and above the mylohyoid muscle, and is part of the suprahyoid group of fascial spaces.

It is a potential space located between the mylohyoid muscle superiorly, the platysma muscle inferiorly, under the chin in the midline.

It may be absent or doubled, lie beneath the carotid artery, or be inserted into the omohyoid, or mylohyoid muscles.

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

It is situated above the deep portion of the submandibular gland, on the hyoglossus muscle, near the posterior border of the mylohyoid muscle.

As the inferior alveolar artery enters the foramen, it gives off a mylohyoid branch which runs in the mylohyoid groove, and supplies the mylohyoid muscle.

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

Secretions are delivered into the Wharton's ducts on the deep portion after which they hook around the posterior edge of the mylohyoid muscle and proceed on the superior surface laterally.

Note, posteriorly, the lingual nerve is superior to the submandibular duct and a portion of the submandibular salivary gland protrudes into the space between the hyoglossus and mylohyoid muscles.

A cervical ranula occurs when the spilled mucin dissects its way through the mylohyoid muscle, which separates the sublingual space from the submandibular space, and creates a swelling in the neck.

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.

The triangle formed by the intermediate tendon of the digastric muscle, the posterior border of the mylohyoid muscle, and the hypoglossal nerve is sometimes called Pirogov's, Pirogoff's, or Pirogov-Belclard's triangle.

Laterally, in between the hyoglossus muscle and the mylohyoid muscle lay several important structures (from superior in inferior): sublingual gland, submandibular duct, lingual nerve, vena comitans of hypoglossal nerve, and the hypoglossal nerve.

It descends in a groove on the deep surface of the ramus of the mandible, and reaching the under surface of the mylohyoid muscle, it supplies both the mylohyoid and the anterior belly of the digastric muscle.

The mylohyoid muscle originates from the anterior (front) part of the mylohyoid line, while the posterior (back) part of this line, near the alveolar margin, gives attachment to a small part of the constrictor pharyngis superior, and to the pterygomandibular raphe.

Along with the anterior belly of the digastric muscle, the mylohyoid muscle is innervated by the mylohyoid nerve, a branch of the inferior alveolar nerve, which is a branch of the mandibular nerve V3, a division of the trigeminal nerve also known as cranial nerve V.
