El músculo geniogloso es un músculo extrínseco de la lengua. Es un músculo grande y grueso que contribuye de manera significativa a la forma de la lengua. Inserciones: se origina en la sínfisis mandibular. Se inserta en el cuerpo del hueso hioides y a lo largo de toda la lengua. Función: protrusión («sacar la lengua») y depresión de la lengua. Inervación: nervio hipogloso. Irrigación sanguínea: arteria lingual, con aportaciones de la arteria amigdalina. By TeachMeSeries Ltd (2026) Fig. 1: los músculos extrínsecos de la lengua.

Learn More Frequent questions What is the genioglossus muscle? The genioglossus muscle is a large, extrinsic muscle of the tongue that plays a crucial role in shaping its form. It is primarily responsible for protruding and depressing the tongue. Where does the genioglossus muscle originate and insert? The genioglossus muscle originates from the mandibular symphysis and inserts into the body of the hyoid bone as well as along the entire length of the tongue. This positioning allows it to effectively influence tongue movement. What is the primary function of the genioglossus muscle? The primary function of the genioglossus muscle is to protrude and depress the tongue, facilitating actions such as sticking out the tongue. This muscle is essential for various oral functions, including speech and swallowing. Which nerve innervates the genioglossus muscle? The genioglossus muscle is innervated by the hypoglossal nerve. This nerve is crucial for controlling the movements of the tongue. What are the blood supply sources for the genioglossus muscle? The genioglossus muscle receives its blood supply primarily from the lingual artery, with contributions from the tonsillar artery. This vascularisation supports its vital functions in the oral cavity. Valora este artículo
