Infrahyoid muscles

This tutorial covers the anatomy, function, and clinical relevance of the infrahyoid muscles, which include the omohyoid, sternothyroid, thyrohyoid, and sternohyoid. Each muscle's origin, insertion, innervation, and function are detailed, with emphasis on their roles in depressing the hyoid bone and larynx. The tutorial also highlights the clinical implications of damage to the ANSA cervicalis, which can affect these muscles, leading to swallowing difficulties and voice changes.

What is the unique characteristic of the sternothyroid muscle compared to other infrahyoid muscles?

How does the thyrohyoid muscle contribute to the movement of the hyoid and thyroid bones?

What clinical issues can arise from damage to the ansa cervicalis?
