CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): ABSTRACT: Long-term disturbance of the calcium homeosta-sis of motor endplates (MEPs) causes necrosis of muscle fibers. The onset of morphological changes in response to this disturbance, particularly in relation to the fiber type, is presently unknown. Omohyoid muscles of mice were incubated for 1–30 minutes in Conclusion: This study provides a normal database for morphological and morphometric details of omohyoid muscle. It is significant from the surgical point of view as it is in close relation to the great vessels of the neck and certain group of lymph : Nandini Prashanth Bhat, Arvind Kumar Pandey, C Divya, Sushma R Kotian, Sneha G Kalthur. Sternohyoid: A superficial muscle which originates from the sternum and attaches onto the hyoid bone. Omohyoid: Located laterally to the sternohyoid, the omohyoid muscle is split in two parts attached by a tendon. The inferior region originates from the scapula, joins the . The English name for this muscle is the muscle of the shoulder and the hyoid bone. The term omo comes from the Greek word omos meaning “shoulder” and the term hyoid comes from its resemblance to the Greek letter upsilon (u), which is aspirated as hy.

The infrahyoid muscles, or strap muscles, are a group of four pairs of muscles in the anterior (frontal) part of the four infrahyoid muscles are: the sternohyoid, sternothyroid, thyrohyoid and omohyoid muscles.. Excluding the sternothyroid, the infrahyoid muscles either originate from or insert on to the hyoid bone.. The term infrahyoid refers to the region below the hyoid bone, while Actions: Depress the hyoid bone. Other muscles "depress" and elevate the hyoid bone. What is the real function of the Omohyoid? (In people or in animals?) It is unusual and mysterious for Wikipedia to describe a muscle's physical shape, insertion, origin, sheathing, layout etc. without disclosing its actual function in the body.

The omohyoid muscle is an infrahyoid muscle of the neck that is innervated by the ansa cervicalis of the cervical plexus receiving fibers from the ventral rami of C1–C3 spinal nerves.

The omohyoid is a paired, flat strap of muscle that is made up of superior and inferior bellies joined by an intermediate tendon. The omohyoid and sternohyoid muscles are the lateral and medial margins of the primitive sterno‐cleido‐omo‐hyoid muscle, most of which has been replaced by the omohyoid fascia.

The lower attachment of the omohyoid muscle is highly by: Pg fig. A - there was no line demarcating the omoclavicular triangle and the label "omoclavicular triangle" is therefore just pointing to the posterior belly of the omohyoid muscle.

Pg fig. A - The midline is a defining landmark that separates the /5(80). Anatomical study of the human omohyoid muscle: Regarding intermediate morphologies between normal and anomalous morphologies of the superior belly Reiki Sukekawa Department of Morphological Biology, Division of Oral Anatomy, Ohu University School of Dentistry, Tomita, Koriyama, JapanCited by: Unusual morphology of the superior belly of omohyoid muscle.

Though anomalies of the superior belly of the omohyoid have been described in medical literature, absence of superior belly of omohyoid is rarely reported.

Herein, we report a rare case of unilateral absence of muscular part of superior belly of omohyoid. Omohyoid (OH) muscle is one of the infrahyoid muscles that consist of superior and inferior bellies.

The two bellies are continuous to each other at the intermediate tendon. Inferior belly takes origin form the superior border of the scapula, close to the suprascapular : Rajesh Thangarajan, Prakashchandra Shetty, Srinivasa Rao Sirasanagnadla, Melanie Rose D'souza.

InLoth considered the omohyoid muscle to be a remnant of the sterno-cleido-omohyoid muscle, which really consists of two layers, a sterno-cleido-hyoid portion and a omohyoid portion and classified the variations of omohyoid muscle as follows.

Primitive forms: Type 1. Having only a cleido-hyoid. Type by: An unusual variation of the omohyoid muscle and review of literature Article Literature Review (PDF Available) in Annals of Anatomy - Anatomischer Anzeiger (5) October with. The lower part of the external muscle grows in the external and inferior direction and becomes the omohyoid, which runs obliquely in the lateral cervical area.

21 Therefore, anomalies caused by the adhesion of the fetal omohyoid and the cleido-sterno-hyoideus are from primitive morphology of the splenius. 15, 16, 22 It has been suggested that because the human omohyoid is degenerating, the Cited by:   Omohyoid, or omohyoideus, is a muscle with two bellies.

The inferior belly originates from the superior border of the scapula and runs from posterior to. The omohyoid muscle is a muscle that depresses the hyoid.

It is located in the front of the neck and consists of two bellies separated by an intermediate tendon. Its superior belly serves as the most lateral member of the infrahyoid muscles, located lateral to both the sternothyroid and thyrohyoid muscles.

Its name derives from the Greek "omos" meaning shoulder, giving one of its attachments, and "hyoid", Insertion: Intermediate Tendon (Inferior Belly). During laboratory dissections for medical undergraduate students, unusual morphology of the superior belly of the omohyoid muscle has been observed in formalin embalmed male cadaver of South Indian origin.

The muscular part of the superior belly of the omohyoid was completely absent. The omohyoid muscle is a thin, long muscle located on both sides of the neck. This muscle originates from the top of each of the scapulae (shoulder blades) and then travels up through the neck and attaches to the bottom of the hyoid bone.

The hyoid bone is. Though anomalies of the superior belly of the omohyoid have been described in medical literature, absence of superior belly of omohyoid is rarely reported.

Omohyoid muscle syndrome (OMS) is a rare clinical condition that has the pathognomonic feature of the appearance of a lateral neck mass when swallowing due to dysfunction of the omohyoid muscle. Abstract. Omohyoid muscle syndrome is a rare cause of an X-shaped bulging lateral neck mass that occurs on swallowing.

This is a diagnostic case report of a year-old mixed martial arts athlete who acquired this by: 3. The omohyoid muscle is a thin, relatively long muscle located in each side of the neck. In this lesson, learn about the origin, innervation, and function of the omohyoid muscle.

The omohyoid muscle is a key to finding the suprascapular nerve when it is hard to find. They run closely together from the lateral neck toward the scapular notch. • An elongated transverse process can be defined as one that extends more laterally than the normal cervical transverse process (lateral mass).

Our work represents the first time an anatomical study focused on the morphology of the inferior belly of the omohyoid muscle and its potential use as a free flap has been performed.

Our results show that the inferior belly is a small and thin muscle, with average measures of 93 mm × 12 mm × mm, a trait that could prove to be advantageous.

During laboratory dissections for medical undergraduate students, unusual morphology of the superior belly of the omohyoid muscle has been observed in formalin embalmed male cadaver of South Indian origin.

The muscular part of the superior belly of the omohyoid was completely absent. The inferior belly originated normally from the upper border Author: Rajesh Thangarajan, Prakashchandra Shetty, Srinivasa Rao Sirasanagnadla, Melanie Rose D'souza.

The omohyoid muscle is located slightly lateral and deep to the clavicular head of the sternocleidomastoid muscle approximately ¾ to 1 inch above the superior margin of the clavicle. Given the relationship of the great vessels of the neck to the omohyoid muscle, care must be taken when placing needles in this anatomical area.

Evidence compatible with this hypothesis comes from the knowledge that the omohyoid is a muscle with many anatomic variations.

8 Examples include duplication 9 or absence 10 of either of or both of its bellies, the inferior belly attaching to the clavicle directly or the superior fused with the sternohyoid.
