Explanation: 

Detailed explanation-1: -The mylohyoid muscle or diaphragma oris is a paired muscle of the neck. It runs from the mandible to the hyoid bone, forming the floor of the oral cavity of the mouth.

Detailed explanation-2: -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.

Detailed explanation-3: -The mylohyoid, genioglossus, and geniohyoid muscles comprise the muscular floor of the oral cavity. This region is divided into right and left halves by the lingual frenulum and contains the ostia of the submandibular and sublingual salivary glands.

Detailed explanation-4: -Infrahyoid muscles are also known as “strap muscles” which connect hyoid, sternum, clavicle and scapula. They are located below the hyoid bone on the anterolateral surface of the thyroid gland and are involved in movements of the hyoid bone and thyroid cartilage during vocalization, swallowing and mastication.
