Detailed explanation-1: -The hyoglossus acts to both depress and retract the tongue. It receives its motor innervation via the hypoglossal nerve . Its bloody supply is comprised mainly through the sublingual branch of the lingual artery with additional supply from the submental branch of the facial artery.
Detailed explanation-2: -These muscles attach to the superior aspect of the hyoid bone, and their main combined function is to elevate the hyoid and larynx and move them superiorly and anteriorly.
Detailed explanation-3: -The Hypoglossal Nerve is the 12th Cranial Nerve (Cranial Nerve XII). It is mainly an efferent nerve for the tongue musculature. The nerve originates from the medulla and travels caudally and dorsally to the tongue.
