The lingual vein passes medial to the hyoglossus. The lingual artery passes deep to the hyoglossus. Laterally, in between the hyoglossus muscle and the mylohyoid muscle, lay several important structures (from upper to lower): sublingual gland, submandibular duct, lingual nerve, vena comitans of hypoglossal nerve, and the hypoglossal nerve.
The hyoglossal membrane is a strong fibrous lamina, which connects the under surface of the root of the tongue to the body of the hyoid bone. It is characterized by a posterior widening of the lingual septum. [1] This membrane receives, in front, some of the fibers of the Genioglossi. Inferior fibers are attached to hyoglossal membrane, and to ...
The hypoglossal nerve provides motor control of the extrinsic muscles of the tongue: genioglossus, hyoglossus, styloglossus, and the intrinsic muscles of the tongue. [2] These represent all muscles of the tongue except the palatoglossus muscle, which is innervated by the vagus nerve. [2] The hypoglossal nerve is of a general somatic efferent ...

The inferior longitudinal muscle of the tongue is an intrinsic muscle of the tongue. [1] It is thin and oval in cross-section. It is situated between the paramedian septum, and the lateral septum. [2] It extends from the root to the apex of the tongue. Posteriorly, some of its fibers attach onto the body of the hyoid bone.
The chondroglossus muscle is about 2 cm long. It arises from the medial side and base of the lesser horn of the hyoid bone. [1] It passes directly upward. [1] It then inserts by blending with the intrinsic muscles of the tongue, between the hyoglossus and genioglossus.
The lingual septum is closely associated with the hyoglossus membrane, allowing the binding of the tongue to the hyoid muscles. [1] Visualization through implementing a vertical groove along the tongue called the median sulcus. It is thicker behind than in front, and occasionally contains a small fibrocartilage, about 6 mm. in length.
It begins by numerous branches from the superficial surface of the gland, and runs forward between the mylohyoid, hyoglossus, and genioglossus muscles. It then passes between the sublingual gland and the genioglossus and opens by a narrow opening on the summit of a small papilla (the "sublingual caruncle") at the side of the frenulum of the tongue.
