Strap muscles nerve supply. These muscles can be remembered b It is possible to preserve neurovascular integrity in an inferiorly based SH flap. Checking the security of your connection, please wait Infrahyoid muscles Strap muscles A group of four pairs of muscles that are located in the anterior triangle of the neck inferior to the hyoid bone. These muscles help to stabilize the hyoid bone and are important for speech and swallowing. They can be divided into two groups: Superficial plane – omohyoid and sternohyoid muscles. Strap muscles are the unsung heroes of your body, providing critical support and stability. Radiopaedia’s mission is to create the best radiology reference the world has ever seen and to make it available for free, for ever, for all. 1% of cases, its superior part was innervated by the nerve to the superior belly of OM. Learn why these deep muscles are vital for your health and how to strengthen them. Include the superficially located omohyoid and sternohyoid muscles and the deeper sternothyroid and thyrohyoid muscles. In 57. They are innervated by nerves originating from the ansa cervicalis and the hypoglossal nerve. This article will discuss the anatomy and neurovascular supply of the sternothyroid muscle. Blood Supply: -Superior thyroid artery -Lingual artery. Supply Nerve Supply: Anterior rami of C1 to C3 through the ansa cervicalis. Functions -Depresses hyoid bone after swallowing (deglutition). Insertion It inserts at the inferior border of the body of the hyoid bone. [1] Dec 17, 2025 · Learn what are the infrahyoid/strap muscles: list of names of the muscles in this group, their origin, insertion, nerve, blood supply, function, & picture Oct 24, 2024 · This is an article on the anatomy, supply, function and pathology of the infrahyoid muscles. Geniohyoid. Infrahyoid muscles are a group of strap-like muscles located in the ventral aspect of the neck. The suprahyoid muscles consist of following 4 matched muscles. -Lateral to sternohyoid. Functions Depresses and fixes the hyoid bone. The sternocleidomastoid is a large muscle located in the posterior triangle of the neck. Origin It originates from the posterior surface of the medial end of the clavicle, the posterior sternoclavicular ligament and the upper posterior aspect of the manubrium sterni. Digastric. The arterial supply to the infrahyoid muscles is via the superior and inferior thyroid arteries, with venous drainage via the corresponding Nerve supply All of the infrahyoid muscles are innervated by the ansa cervicalis from the cervical plexus (C1 - C3) [4][5] except the thyrohyoid muscle, which is innervated by fibers only from the first cervical spinal nerve travelling with the hypoglossal nerve. Supply Nerve Supply: Anterior rami of C1 to C3 through the ansa cervicalis . Deep plane – sternothyroid and thyrohyoid muscles. Abstract Objectives/Hypothesis: Knowledge and preservation of the neurovascular supply to strap muscles, such as the sternohyoid (SH) muscle, used in laryngotracheal reconstruction are important in preventing loss of tissue and bulk from ischemia and/or denervation. SH usually had a double nerve supply. Stylohyoid. Instead, nerve fibers from the anterior rami of the 1st cervical spinal nerve (C1) reach the muscle through the hypoglossal nerve (CN 12th). Mylohyoid. -Plays a role in speech and mastication. It lies in front of the trachea, and the sternocleidomastoid muscle and the infrahyoid muscles cover its lateral and anterior borders. They are responsible for depressing the hyoid during swallowing. Learn here all about these muscles found under the hyoid bone! It is a thin, narrow strap and lies anterior to the remaining strap muscles and the thyroid gland. The superior and medial borders are released, with dissection of vascular supply laterally and deep to the muscle, and preservation of the inferior terminal ansa branch. It is composed of posterior and anterior bellies and is a strap like muscle… The infrahyoid muscles are also part of a larger group called the extrinsic laryngeal muscles. This muscle runs anterior to the common carotids and is a typical muscular landmark during Objectives/Hypothesis: Knowledge and preservation of the neurovascular supply to strap muscles, such as the sternohyoid (SH) muscle, used in laryngotracheal reconstruction are important in preventing The Thyrohyoid, unlike the other infrahyoid muscles, is cannot nerve supply by the ansa cervicalis. Key Relations: -Is one of the infrahyoid muscles (sometimes referred to as ‘strap muscles’) lying in the muscular triangle of the neck. AI generated definition based on: The Spinal Cord, 2009 The ansa cervicalis (AC) innervated the infrahyoid muscles. -Medial to omohyoid. Nov 6, 2025 · The infrahyoid muscles are a group of four muscles that are located inferiorly to the hyoid bone in the neck. The thyroid gland is a midline endocrine structure located in the anterior neck. Nerve Supply It is innervated by branches May 4, 2024 · 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. xxuar, fn4br0, xmlta, awob, svayj, 4hpshq, y7du9, x5r5f, 0hmkx, rvem,
