Anatomy & Physiology: Muscles—Thyrohyoid.

Structure.

• Origin: thyroid cartilage of larynx.
• Insertion: greater horn of hyoid.

Function.

• Concentric action: elevates thyroid cartilage of larynx; depress hyoid.
• Reverse mover action: elevate thyroid cartilage.
• Eccentric action: controls/restrains/slows elevation of hyoid, depression of thyroid cartilage.
• Isometric action: stabilize hyoid bone and thyroid cartilage.
• Innervation: branches of spinal nerves C1-C3; descending hypoglossal XII nerve.
• Arterial supply: superior thyroid artery.
