Skeletal System

Outline

Introduction: talk about normal physiology-anatomy of bone tissue, functions, structure etc.… The skeletal system is a flawless adaption for its functions of body protection and movement. Our bones form a tower of skeleton arrangement designed to keep humans standing upright and balanced. The skeleton is partitioned into the axial skeleton, which encompasses the bones of the skull, the vertebral column, and the thoracic cage. The second partitioning of the skeleton is the appendicular skeleton, which include the bones of the limbs and the bones responsible for holding the limbs to the axial skeleton. The bones in the skeletal system are essential for the body shape, support of the body, protection of soft body organs, movement, storage

Five different cell types encompass microscopic bone and include the osteogenic cell, osteoblast, osteocyte, and osteoclast. Each varying cell type serves a particular purpose for bone development. The chemical composition of the bone includes certain substance proportions to maintain strong bone support. Bone tissue must contain 65% of its mass from tightly packed calcium phosphates (E.N. Marieb 2015). The tightly packed calcium phosphate is detrimental to the bones ability to resist breaking and maintain longevity against the perils of all activity placed on the bones during

Bone resorption acts to cleanse the bone that has remained for a long period of time and reduce the calcium salts that have crystallized, which causes the bone to become more brittle. When bone resorption occurs at an increasing rate, and bone deposit fails to keep up, the result is a devastating bone disorder called osteoporosis. Osteoporosis is prominently characterized by a decline of bone mass, causing a fragility susceptible to fracture. There are three main features that contribute to the development of Osteoporosis, as follows; peak bone mass is less than optimal, excessive bone resorption causes loss of bone mass and structural damage, or inadequate bone formation occurs in response to bone resorption (Becker, C., 2008). During childhood and adolescence bone growth exceeds bone resorption until peak mass is obtained during adulthood. Peak bone mass is achieved by age 40, but varies cross culturally and between genders. After year of peak bone mass, the onset of menopause for women and normal aging in both sexes, bone structure and bone mass begin to deteriorate. The rate at which this deterioration occurs and the pattern of bone loss is most probably
