Thyrohyoid muscle
(Redirected from Thyrohyoideus)
Thyrohyoid muscle is a small skeletal muscle on the neck which depresses the hyoid and elevates the larynx. It is a part of the infrahyoid muscles group.
Anatomy[edit | edit source]
The thyrohyoid muscle originates from the oblique line on the lamina of the thyroid cartilage, and inserts into the lower border of the hyoid bone. It is innervated by the first cervical spinal nerve via the hypoglossal nerve.
Function[edit | edit source]
The thyrohyoid muscle depresses the hyoid bone and elevates the larynx, actions that are important in swallowing and speech.
Clinical significance[edit | edit source]
Dysfunction of the thyrohyoid muscle can contribute to swallowing disorders, known as dysphagia. It may also be involved in conditions that cause neck pain.
