Gastrocnemius muscle the medial condyle of the femur. Its other end forms a common tendon with the soleus muscle; this tendon is known as the calcaneal tendon or Achilles Tendon and inserts onto the posterior surface of the calcaneus, or heel bone. Further, it is considered a superficial muscle as it is located directly under skin, so its shape is clearly visible in a normal human being. Deep to the gastrocnemius (farther from the skin) is the soleus muscle. Some anatomists consider both to be a single muscle, the triceps surae or "three-headed [muscle] of the calf", since they share a common
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.
