Mylohyoid muscle

Introduction The mylohyoid is one of the muscles essential in performing the functions of swallowing and speaking. It is a flat and triangular muscle that originates from the mandible near the molars hence the prefix “mylo” (Greek for molars) and inserts on the hyoid bone. The mylohyoid mainly functions to elevate the hyoid bone, elevate the oral cavity, and depress the mandible. The source of motor innervation is via the mylohyoid nerve, which is a division of the inferior alveolar nerve, a branch of the mandibular division of the trigeminal nerve. The blood supply is from the mylohyoid artery, a branch of the inferior alveolar artery which originates from the internal maxillary artery. The mylohyoid muscle forms a contractile hammock to support the oral cavity base. Structure and Function The mylohyoid muscle is composed of two different subunits that come together to form the entire mylohyoid muscle. The mylohyoid muscle originates from the mylohyoid line located within the interior surface of the mandible near the molars of the lower jaw and continues along the entirety of the inner mandibular rim. The mylohyoid muscles on each side of the inner surface of the mandible meet medially at a median tendon called the mylohyoid raphe. The middle and anterior fibers of the mylohyoid muscle form the mylohyoid raphe which extends from the symphysis menti to the body of the hyoid bone. The posterior fibers of the mylohyoid muscle pass medial and downward to insert on the body of...

A thorough knowledge of the anatomy of the denture bearing surfaces is paramount to designing and fabricating functional dentures. The functional anatomy of the denture foundation areas of the maxilla and mandible is presented in detail – in particular, the relationship of these anatomic structures that impact retention, stability and support. [fbcomments] ANATOMY OF THE DENTURE FOUNDATION AREAS – COURSE TRANSCRIPT • 1. 2.

EDENTULOUS ANATOMY In order to properly construct a denture, one must understand the anatomy and physiology of the edentulous patient. A thorough knowledge of the origins and kinetics of the muscles of mastication, facial expression, tongue and floor of the mouth is essential. • 3. Key Concepts in Prosthodontics Retention : Resistance to vertical displacement away from the bearing surfaces Stability : Resistance to lateral displacement Support : Factors of the bearing surfaces that absorb or resist forces of occlusion When the key anatomic landmarks and their role with respec...

Function of Submandibular Glands The submandibular gland produces saliva, which moistens the mouth and aids in chewing, swallowing, digestion, and helps to keep the mouth and teeth clean. Unstimulated, the submandibular glands provide the majority of saliva to the mouth. On stimulation, the parotid gland takes over, producing the majority of saliva. The most common symptoms of Sjögren’s syndrome are dry eyes and mouth and muscle and joint pain. Additionally, you may notice an abnormal taste in the mouth, a burning sensation in the eyes, blurry vision, trouble chewing or swallowing, cough, enlarged salivary glands, tooth decay, and vaginal dryness. • Mucoepidermoid carcinomas are the most common cancer of the salivary glands. They most often occur in the parotid glands but can also occur in the submandibular glands. • Adenoid cystic carcinoma often spreads along nerves, which makes it difficult to get rid of. The outlook is best for those with smaller tumors. • Adenocarcinomas are cancers that start in the gland cells. There are many types of adenocarcinomas, including acinic cell carcinoma, polymorphous low-grade adenocarcinoma (PLGA), adenocarcinoma, not otherwise specified (NOS), and rare adenocarcinomas. • Malignant mixed tumors are tumors of multiple tissue types. They include carcinoma ex pleomorphic adenomas, carcinosarcoma, and metastasizing mixed tumor. • Rare salivary gland cancers include squamous cell carcinoma, epithelial-myoepithelial carcinoma, anaplastic sma...
