Omohyoid muscle Omohyoid muscle 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", giving the other attachment - the hyoid bone. It arises from the upper border of the scapula, and occasionally from the superior transverse scapular ligament which crosses the scapular notch, its
Artificial bone which is one of the most stable forms of calcium phosphate, makes up about 60 to 65 percent of the bone. The rest of the bone is composed of materials including chondroitin sulfate, keratan sulfate and lipid. Increased research and knowledge regarding the organization, structure of properties of collagen and hydroxyapatite have led to many developments in collagen-based scaffolds in bone tissue engineering. The structure of hydroxyapatite is very similar to that of the original bone, and collagen can act as molecular cables and further improve the biocompatibility of the implant. In the United States, more than 6.5 million bone
