Learn More Frequent questions What is the function of the hyoglossus muscle? The hyoglossus muscle functions to depress and retract the tongue. This action is essential for various oral movements, including swallowing and speech. Where is the hyoglossus muscle located? The hyoglossus muscle is situated in the floor of the oral cavity, immediately lateral to the geniohyoid muscle. Its positioning is crucial for its role in tongue movement. What are the attachments of the hyoglossus muscle? The hyoglossus muscle originates from the hyoid bone and inserts into the lateral aspect of the tongue. This specific attachment allows it to effectively influence tongue position. Which nerve innervates the hyoglossus muscle? The hyoglossus muscle is innervated by the hypoglossal nerve. This nerve is vital for controlling the movements of the tongue. What is the blood supply to the hyoglossus muscle? The blood supply to the hyoglossus muscle primarily comes from the lingual artery, with additional contributions from the tonsillar artery. This vascularisation supports the muscle's function and health. Valora este artículo
