Anatomical terms of muscle This may be a bone, a tendon or the subcutaneous dermal connective tissue. Insertions are usually connections of muscle via tendon to bone. The insertion is a bone that tends to be distal, have less mass, and greater motion than the origin during a contraction. Muscles may also be described by the direction that the muscle fibres run in. Hypertrophy is increase in muscle size from an increase in size of individual muscle cells. This usually occurs as a result of exercise. Anatomical terms of muscle Muscles are described using unique anatomical terminology according to their actions and structure. There
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
