Mandible (Posterior view) (English)

The internal surface of the body, angle and ramus of the mandible can be seen from this posterior view. The midline of the internal surface of the body of the mandible presents with two bony indentenations known as the sublingual and submandibular fossae. These structures house the sublingual and submandibular salivary glands, respectively. The mental spines (superior and inferior) are small midline processes on the body of the mandible which act as an attachment site for the genioglossus muscle. Along the base of the mandible are two rough rough, shallow depressions known as the digastric fossae which serve as an origin site for the anterior belly of the digastric muscle. The internal surface of the angle of the mandible presents with a roughening for the attachment of the medial pterygoid muscle, known as the pterygoid tuberosity.
