GENERAL HISTOLOGY

Detailed explanation-1: -The genioglossus muscle is a fan-shaped muscle that is involved in forming most of the tongue mass. It emerges from the superior mental spines and inserts on the hyoid bone as well as the inferior portion of the tongue.

Detailed explanation-2: -Origin: The inferior longitudinal lingual muscle originates at the root of the tongue. Insertion: This muscle inserts into the apex, or tip, of the tongue.

Detailed explanation-3: -To reach the tongue and insert into posterolateral aspects, it passes through the oropharyngeal triangle. The longitudinal part of the styloglossus will then blend with fibers of the inferior longitudinal muscle, and the oblique part of the styloglossus muscle will blend with fibers of the hyoglossus muscles.

Detailed explanation-4: -The genioglossus (GG, tongue) muscle plays an important role in maintaining upper airway patency. The GG is responsible for tongue protrusion and stiffens the tongue and prevents posterior tongue displacement and upper airway closure. The GG is a phasic respiratory muscle.
