Secondary centers of ossificationSecondary centers of ossification appear in the epiphysis of tubular bone thin layer Finally, the cartilaginous tissue transforms into bony tissue except thin layer b/w epiphysis and diaphysis of the bone. The layer is named cartilage epiphysialis or metaphysic. The cartilage epiphysis gives growing of bones in length (to 18-25 years) Calcium has been singled out as a major public health concern today because it is critically important to bone health and the average Vitamin D is important for good bone health because it aids in the absorption and utilization of calcium. Physical activity is important for bone health throughout life. It helps to increase or preserve bone mass and to reduce the risk of falling. Maintaining a healthy body weight is important for bone health throughout life. Being underweight raises the risk of fracture and bone loss. Fractures are commonly caused by falls, and thus fall prevention offers another opportunity to protect bones, particularly in those over age 60.. Reproductive issues can affect bone health. Pregnancy and lactation generally do not harm the skeleton of healthy adult women. Several medical conditions and prescription medications can affect bone health through various mechanisms, and health care professionals should treat the presence of such conditions Smoking can reduce bone mass and increase fracture risk and should be avoided for a variety of health reasons. Heavy alcohol use has been associated with reduced bone mass and increased fracture risk. Types of the ostegenesis. Jeneral,Private,Comparative,Age related X-raybone (boneradiography)allows to estimate the external and internal features of the bones.It can be done at the end of the second month of fetal life,when there are points in the cartilage ossification. X-raysof bone sand joints is carried out for the diagnosis of various diseases-osteoporosis,degenerative disc disease,osteoarthritis,flat feet,as well as injuries-open and closed fractures, joint injury.
Anatomical, medical anthropology. Anthropometry. Understanding about norm, variants of the norm, congenital anomalies. Anatomical constitution of the Human body. Types of the body build. Anthropological anatomy or physical anthropology relates to the comparison of the anatomy of different races of humans. Medical anthropology studies "human health and disease, health care systems, and biocultural adaptation". It views humans from multidimensional and ecological perspectives It is one of the most highly developed areas of anthropology and applied anthropology and is a subfield of social and cultural anthropology that examines the ways in which culture and society are organized around or influenced by issues of health, health care and related issues.
