The omohyoid muscle is a muscle in the neck. It is one of the infrahyoid muscles. It consists of two bellies separated by an intermediate tendon. Its inferior belly is attached to the scapula; its superior belly is attached to the hyoid bone. Its intermediate tendon is anchored to the clavicle and first rib by a fascial sling.
Branches of the ansa cervicalis innervate three of the four infrahyoid muscles: the sternothyroid, sternohyoid, and omohyoid muscles (note that the thyrohyoid muscle is the one infrahyoid muscle not innervated by the ansa cervicalis - it is instead innervated by cervical spinal nerve 1 via a separate thyrohyoid branch [2]: 582, 600 ).
Furthermore, Omophydroid Muscle Syndrome - a rare muscle condition which causes chronic soreness and pain swallowing, may be the cause of falsely diagnosed pseudodysphagia. It is also not uncommon for pseudodysphagia to be misdiagnosed with conversion disorder (Globus Pharyngeus) and eating disorders.
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]
After branching from the upper trunk, the nerve passes across the posterior triangle of the neck parallel to the inferior belly of the omohyoid muscle and deep to the trapezius muscle. It then runs along the superior border of the scapula through the suprascapular canal , [ 1 ] in which it enters via the suprascapular notch inferior to the ...
The posterior triangle is crossed, about 2.5 cm above the clavicle, by the inferior belly of the omohyoid muscle, which divides the space into two triangles: an upper or occipital triangle; a lower or subclavian triangle (or supraclavicular triangle)
Celine Dion‘s sister, Claudette Dion, claims her sister has lost control of her muscles due to her Stiff-Person Syndrome — a progressive neurological disorder that affects the brain and the ...
Anterior triangle is defined by the anterior border of the sternocleidomastoid muscle, inferior edge of the mandible and the midline of the neck. It contains the stylohyoid, digastric, mylohyoid, geniohyoid, omohyoid, sternohyoid, thyrohyoid and sternothyroid muscles.
