El músculo omohioideo es un músculo infrahioideo del cuello. Consta de dos vientres musculares unidos por un tendón muscular. Inserciones: El vientre superior se origina en el hueso hioides y el vientre inferior, en la escápula. Los dos vientres musculares están unidos por un tendón intermedio, que se fija a la clavícula mediante la fascia cervical profunda. Acciones: deprime el hueso hioides. Inervación: ramos anteriores de C1-C3, transportados por una rama de la asa cervical. Irrigación sanguínea: arteria tiroidea superior (rama de la arteria carótida externa) y arteria tiroidea inferior (rama del tronco tirocervical).

Learn More Frequent questions What is the omohyoid muscle? The omohyoid muscle is an infrahyoid muscle located in the neck, consisting of two muscle bellies connected by an intermediate tendon. It plays a key role in depressing the hyoid bone. Where does the omohyoid muscle attach? The superior belly of the omohyoid muscle originates from the hyoid bone, while the inferior belly arises from the scapula. The two bellies are joined by an intermediate tendon that attaches to the clavicle via deep cervical fascia. What is the function of the omohyoid muscle? The primary function of the omohyoid muscle is to depress the hyoid bone. This action is important for various movements involved in swallowing and speaking. What nerves innervate the omohyoid muscle? The omohyoid muscle is innervated by the anterior rami of spinal nerves C1 to C3, which are conveyed through a branch of the cervical plexus. This innervation is essential for muscle contraction and function. What is the blood supply to the omohyoid muscle? The omohyoid muscle receives its blood supply from the superior thyroid artery, a branch of the external carotid artery, and the inferior thyroid artery, which branches from the thyrocervical trunk. This vascular supply is crucial for the muscle's health and function. Valora este artículo
