Digastric muscle cornu of the hyoid bone; this is termed the suprahyoid aponeurosis. The digastricus (digastric muscle) consists of two muscular bellies united by an intermediate rounded tendon. The two bellies of the digastric muscle have different embryological origins, and are supplied by different cranial nerves. Each person has a right and left digastric muscle. In most anatomical discussions, the singular is used to refer to a muscle, even when each person actually has two of that muscle—one on the right side, and another on the left. For example, we speak of the deltoid, even though there is one deltoid in each
Bone health skeleton through physical activity promotes positive bone remodelling and decreases levels of homocysteine, independently from nutritional intake. Four methods have been proposed regarding the interaction of homocysteine and bone; increase in osteoclast activity, decrease in osteoblast activity, decrease in bone blood flow, and direct action of homocysteine on bone matrix. Homocysteine inhibits lysyl oxidase which is responsible for post-translational modifications of collagen, a key component to bone structure Osteoclasts are located on the surface of bones and form resorption pits by excreting H+ to the bone surface removing hydroxyapatite, multiple bone minerals, and organic components: collagen and dentin. The purpose
