El constrictor faríngeo medio es un músculo de la faringe. Es el músculo central de los tres músculos constrictores faríngeos existentes y se encuentra dentro de la laringofaringe. Inserciones: se origina en el ligamento estilohioideo y el hueso hioides. Se inserta posteriormente en el rafe faríngeo. Acción: Durante la deglución, contrae la pared de la faringe para impulsar el bolo alimenticio hacia abajo. Inervación: nervio vago. Irrigación sanguínea: rama faríngea de la arteria faríngea ascendente con aportes de la rama amigdalina de la arteria facial.

Learn More Frequent questions What is the constrictor faríngeo medio? The constrictor faríngeo medio is a muscle located in the pharynx, specifically within the laryngopharynx. It is the central muscle among the three pharyngeal constrictors and plays a crucial role in swallowing. What are the attachments of the constrictor faríngeo medio? This muscle originates from the stylohyoid ligament and the hyoid bone, inserting posteriorly into the pharyngeal raphe. These attachments are essential for its function during swallowing. What is the function of the constrictor faríngeo medio during swallowing? The constrictor faríngeo medio contracts the pharyngeal wall to propel the food bolus downward during swallowing. This action is vital for the effective movement of food through the pharynx. Which nerve innervates the constrictor faríngeo medio? The constrictor faríngeo medio is innervated by the vagus nerve. This innervation is important for coordinating the muscle's contraction during the swallowing process. What is the blood supply to the constrictor faríngeo medio? The blood supply to the constrictor faríngeo medio comes primarily from the pharyngeal branch of the ascending pharyngeal artery, with additional contributions from the tonsillar branch of the facial artery. This vascular support is crucial for the muscle's function and health. Valora este artículo
