What are the 3 parts of the mandible?
The mandible is made up of the following parts: the body and two rami.
- Body. The body is the anterior portion of the mandible and is bound by two surfaces and two borders.
- Ramus. The ramus contributes to the lateral portion of the mandible on either side.
- Coronoid Process.
- Condyloid Process.
What structures enter the mandibular foramen?
The mandibular foramen is an opening at the internal aspect of the ramus of the mandible. The inferior alveolar branch of the mandibular division of the trigeminal nerve, as well as the inferior alveolar vessels, enter the foramen and supply the lower jaw.
What articulates with the mandible?
The mandible articulates with the temporal bone to form the temporomandibular joint which is discussed in more detail here.
What is mandibular notch?
Medical Definition of mandibular notch : a curved depression on the upper border of the lower jaw between the coronoid process and the condyloid process. — called also sigmoid notch.
What is the base of the mandible?
The base of mandible is the lower part of the body of the mandible, excluding the alveolar part. This definition incorporates text from a public domain edition of Gray’s Anatomy (20th U.S. edition of Gray’s Anatomy of the Human Body, published in 1918 – from http://www.bartleby.com/107/).
What is the Ramus of the mandible?

What comes out of the mandibular foramen?
The mandibular foramen contains a branch of the trigeminal nerve (CN V), a branch of the maxillary artery and the inferior alveolar vein. The nerve and blood vessels within the mandibular foramen are the inferior alveolar nerve, artery, and vein.
What attaches to mandibular notch?
The mandibular notch allows for the passage of the masseteric nerve (a branch of the mandibular nerve (V3) division of the trigeminal nerve), the masseteric artery, and the masseteric vein.
What is the mandibular arch?
Medical Definition of mandibular arch : the first branchial arch of the vertebrate embryo from which in humans are developed the lower lip, the mandible, the masticatory muscles, and the anterior part of the tongue.
