Verified step by step guidance1
Understand the location and function of infrahyoid muscles. These muscles are located below the hyoid bone and are involved in depressing the hyoid bone and larynx during swallowing and speech.
Identify the infrahyoid muscles. The primary infrahyoid muscles include the sternohyoid, sternothyroid, thyrohyoid, and omohyoid muscles.
Recognize that the omohyoid muscle is part of the infrahyoid group. It has two bellies, superior and inferior, connected by an intermediate tendon, and it functions to depress the hyoid bone.
Differentiate between infrahyoid and suprahyoid muscles. Suprahyoid muscles are located above the hyoid bone and include the mylohyoid, stylohyoid, digastric, and geniohyoid muscles.
Conclude that among the given options, the omohyoid muscle is the correct answer as it is the only infrahyoid muscle listed.
