The infrahyoid muscles, or strap muscles, are a group of four pairs of muscles in the anterior (frontal) part of the neck. [1] The four infrahyoid muscles are the sternohyoid, sternothyroid, thyrohyoid and omohyoid muscles. [1] Excluding the sternothyroid, the infrahyoid muscles either originate from or insert on to the hyoid bone. [2] The infrahyoid muscles are a group of four muscles under the hyoid bone attaching to the sternum, larynx and scapula.

Infrahyoid "Strap" Muscles Diagram Quizlet
The infrahyoid muscles are a group of four muscles that are located inferiorly to the hyoid bone in the neck. They can be divided into two groups: Superficial plane - omohyoid and sternohyoid muscles. Deep plane - sternothyroid and thyrohyoid muscles. Infrahyoid muscles are also known as "strap muscles" which connect hyoid, sternum, clavicle and scapula. They are located below the hyoid bone on the anterolateral surface of the thyroid gland and are involved in movements of the hyoid bone and thyroid cartilage during vocalization, swallowing and mastication. The infrahyoid neck is the region of the neck extending from the hyoid bone to the thoracic inlet. Traditionally the anatomy of the infrahyoid neck has been subdivided into a group of surgical triangles whose borders are readily palpable bones and muscles (figure). The infrahyoid muscles or strap muscles are a group of four paired muscles in the anterior neck below the hyoid bone, within the muscular triangle. They are responsible for depressing the hyoid during swallowing. These muscles can be remembered by the mnemonic "TOSS". Gross anatomy There are four strap muscles: thyrohyoid : deep and lateral

Introduction The hyoid muscles are superficial muscles in the neck which attach to the hyoid bone. They are grouped according to their position to the hyoid bone, the suprahyoid muscles lie above the hyoid bone and the infrahyoid muscles lie beneath it. These muscles act to stabilise the trachea and play a vital part in swallowing and speech. The Infrahyoid Muscles. The strap, or infrahyoid, muscles are four grouped pairs of anterior cervical muscles, as previously listed. Their primary function is to depress the hyoid bone and larynx during speech and swallowing maneuvers. All except the thyrohyoid receive innervation from the cervical plexus (C1-C3), particularly the ansa cervicalis. The infrahyoid, or strap, muscles are paired bilateral muscle pairs that occupy the area between the sternum and hyoid bone. The innervation of each of the strap muscles is from the ansa cervicalis. The sternothyroid and thyrohyoid are relatively shorter muscles and are deep to the longer omohyoid and sternohyoid muscles. The sternothyroid. The infrahyoid muscles, or strap muscles, are a group of four pairs of muscles in the anterior (frontal) part of the neck. The four infrahyoid muscles are the sternohyoid, sternothyroid, thyrohyoid and omohyoid muscles. Muscles of the neck seen from the front. The infrahyoid muscles are coloured in violet.

Infrahyoid muscles: These are also referred to as "strap muscles." They include four paired muscles on the anterolateral surface of the thyroid gland. The strap muscles result in gross movement of the larynx during swallowing and also adjust the positioning of the larynx during vocalization. The infrahyoid muscles of mammals are a group of strap-like muscles in the ventral aspect of the neck with a rather complex pattern of innervation.
The infrahyoid muscles are an anterior neck muscle group, which means they are present at the front of the neck. Some people may also refer to the infrahyoid muscle group as the strap.

The infrahyoid neck muscles are four strap-like, paired muscles that are situated in the anterior compartment of the neck below the hyoid bone. Because of their appearance, they are also known as strap muscles. Check it out Superficial, suprahyoid, infrahyoid, scalene, prevertebral, suboccipital muscles of the neck.
