Mylohyoid Muscle - Structure

Structure

The mylohyoid muscle is flat and triangular, and is situated immediately above the anterior belly of the digastric muscle. It forms, with its fellow of the opposite side, a muscular floor for the cavity of the mouth. Each submandibular gland is divided into superficial and deep lobes, which are separated by the mylohyoid muscle.

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 inferomedially to insert into the body of the hyoid bone. It thus belongs to the suprahyoid muscles.

The middle and anterior fibers are inserted into a median fibrous raphé extending from the symphysis menti to the hyoid bone, where they joint at an angle with the fibers of the opposite muscle. This median raphé is sometimes absent; the fibers of the two muscles are then continuous.

Famous quotes containing the word structure:

    In the extent and proper structure of the Union, therefore, we behold a republican remedy for the diseases most incident to republican government.
    James Madison (1751–1836)

    Man is more disposed to domination than freedom; and a structure of dominion not only gladdens the eye of the master who rears and protects it, but even its servants are uplifted by the thought that they are members of a whole, which rises high above the life and strength of single generations.
    Karl Wilhelm Von Humboldt (1767–1835)

    Agnosticism is a perfectly respectable and tenable philosophical position; it is not dogmatic and makes no pronouncements about the ultimate truths of the universe. It remains open to evidence and persuasion; lacking faith, it nevertheless does not deride faith. Atheism, on the other hand, is as unyielding and dogmatic about religious belief as true believers are about heathens. It tries to use reason to demolish a structure that is not built upon reason.
    Sydney J. Harris (1917–1986)
