Hyogloss Muscle: Tongue And Swallowing Function

The hyoglossus muscle is a thin, quadrilaterally shaped extrinsic muscle of the tongue. It originates from the hyoid bone, which anchors it when it contracts, and inserts onto the side of the tongue. The hyoglossus muscle is innervated by the hypoglossal nerve and acts to depress, elevate, retract and protract the tongue.

The hyoglossus muscle is one of the extrinsic muscles of the tongue

The hyoglossus muscle is innervated by the hypoglossal nerve (cranial nerve XII). The hypoglossal nerve also innervates three of the four extrinsic muscles: the genioglossus, styloglossus, and hyoglossus, and all four intrinsic muscles. The genioglossus is responsible for the protrusion of the tongue, the styloglossus draws the tongue back and up, and the hyoglossus mediates depression and retraction of the tongue. The intrinsic muscles alter the tongue's shape.

The hyoglossus muscle forms a part of the floor of the submandibular triangle. The submandibular ganglion suspended from the lingual nerve sits on it. Laterally, in between the hyoglossus muscle and the mylohyoid muscle, lie several important structures (from upper to lower): the sublingual gland, submandibular duct, lingual nerve, vena comitans of the hypoglossal nerve, and the hypoglossal nerve. The lingual vein passes medial to the hyoglossus, and the lingual artery passes deep to the hyoglossus.

It originates from the hyoid bone and inserts into the tongue

The hyoglossus muscle is a thin, quadrilaterally shaped extrinsic muscle of the tongue. It originates from the hyoid bone and inserts into the side of the tongue. The hyoid bone anchors the muscle when it contracts. The hypoglossal nerve (cranial nerve XII) innervates the hyoglossus, along with three of the four extrinsic muscles: the genioglossus, styloglossus, and all four intrinsic muscles. The hyoglossus mediates depression and retraction of the tongue, altering its shape.

The hyoid bone is located in the front of the neck, between the chin and the thyroid cartilage. It is a U-shaped bone that is suspended by muscles and ligaments, and it anchors the tongue. The hyoid bone is also the site of attachment for several neck and tongue muscles, including the hyoglossus. The hyoglossus muscle fibres pass almost vertically upward from the hyoid bone to enter the side of the tongue, inserting between the styloglossus and the inferior longitudinal muscle of the tongue.

The geniohyoid and genioglossus muscles arise from the upper part of the body of the hyoid bone and pass to the mandible and the tongue. The mylohyoid muscle, forming the floor of the mouth, is attached to the lower anterior surface of the hyoid bone. The hyoglossus muscle is one of the four extrinsic muscles of the tongue, which attach to the tongue and are responsible for its depression, elevation, protraction, and retraction. The other extrinsic muscles of the tongue are the genioglossus, styloglossus, and palatoglossus.

The hyoglossus muscle is involved in several important functions, including speaking, swallowing, chewing, and breathing. The hypoglossal nerve controls the activity of the tongue during these functions through its inherent flexibility in the firing pattern of motor neurons. The hyoglossus muscle also plays a role in the convexity of the dorsum.

The hypoglossal nerve innervates the hyoglossus muscle

The hyoglossus muscle is one of the extrinsic muscles of the tongue. It mediates the depression of the tongue and is involved in depressing and retracting the tongue. The hyoid bone anchors the hyoglossus muscles when they contract.

The hypoglossal nerve is the twelfth cranial nerve, also known as cranial nerve XII or CN XII. It is a motor nerve that carries signals to and from the brain to control muscle movement. The nerve originates from the medulla and travels caudally and dorsally to the tongue. The hypoglossal nerve carries lower motor neurons that synapse with upper motor neurons at the hypoglossal nucleus.

The hyoglossus muscles pull the tongue back and flatten it. The hypoglossal nerve is involved in controlling tongue movements required for speech and swallowing, including sticking out the tongue and moving it from side to side. If the hypoglossal nerve is damaged, it can affect the ability of the tongue to move and its appearance. Damage to the nerve can cause paralysis, fasciculations, and atrophy of the tongue muscles.

The hyoglossus muscle depresses and retracts the tongue

The hyoglossus muscle is a thin, quadrilaterally shaped extrinsic muscle of the tongue. It originates from the hyoid bone and inserts onto the side of the tongue. The hyoid bone anchors the muscle when it contracts. The muscle is innervated by the hypoglossal nerve (cranial nerve XII).

The hyoglossus muscle is involved in depressing the tongue, while the genioglossus muscle is responsible for protrusion, and the styloglossus muscle draws the tongue back and up. When the tongue is protruded, it would deviate to the affected side due to the contraction of the genioglossus muscle. A retracted tongue may rise higher on the affected side.

The hyoglossus muscle forms a part of the floor of the submandibular triangle. The fibres arising from the body of the hyoid bone overlap those from the greater cornu, passing almost vertically upward to enter the side of the tongue. The muscle is located in the upper neck and the floor of the mouth.

It forms part of the floor of the mouth

The hyoglossus muscle is a thin, quadrilaterally-shaped extrinsic muscle of the tongue. It is one of four extrinsic muscles, the others being the genioglossus, styloglossus, and palatoglossus. The hyoglossus muscle originates from the hyoid bone, which anchors it when it contracts, and inserts onto the side of the tongue. The hypoglossal nerve innervates the hyoglossus, along with the other extrinsic muscles except for the palatoglossus. The hyoglossus acts to depress and retract the tongue, making the dorsum more convex. It also forms part of the floor of the mouth.

The hyoid bone is located in the front of the neck, between the chin and the thyroid cartilage. It is a U-shaped bone that is suspended by muscles and ligaments, and it provides attachment for the muscles of the tongue and the floor of the mouth. The hyoid bone is an important structure for swallowing, speech, and breathing. It also plays a role in keeping the airway open and preventing the tongue from blocking the throat.

The hyoglossus muscle is one of the muscles that attach to the hyoid bone. It originates from the entire length of the greater cornua, or horns, of the hyoid bone, as well as from the body of the hyoid. The fibres arising from the body of the hyoid overlap those from the greater cornu, and they pass almost vertically upward to enter the side of the tongue. The hyoglossus inserts onto the posterior half or more of the sides of the tongue, between the styloglossus and the inferior longitudinal muscle of the tongue.

Several important structures lie laterally between the hyoglossus muscle and the mylohyoid muscle, which also forms part of the floor of the mouth. These structures include the sublingual gland, submandibular duct, lingual nerve, vena comitans of the hypoglossal nerve, and the hypoglossal nerve itself. The lingual nerve is posteriorly superior to the submandibular duct, and a portion of the submandibular salivary gland protrudes into the space between the hyoglossus and mylohyoid muscles.
