Question-1: Discuss the role of two (2) electrolytes in musculoskeletal function

The musculoskeletal system comprises the muscular and the skeletal systems. The purpose of the muscular system is locomotion or movement. The functions of the skeletal system are to provide structural support, protect the body's internal organs, and aid in movement by providing a simple mechanical lever system against which the muscles work.

The role of the two electrolyte under the musculoskeletal function is to meet the unique needs of the high performance in the muscles. When person performs a certain action they replenish the mineral lost. Reaching the optimal performance require the presence of the peak inner health. Therefore, electrolyte vital support is designed to ensure that the minerals lost are covered. The muscles and neurons are activated by electrolyte activity between the extracellular fluid or interstitial fluid and intracellular fluid (Boden, 2008). Both muscle tissue and neurons are considered electric tissues of the body. Electrolytes may enter or exit through the cell membrane structures through protein specialized embedded in the membrane called ion channels.

Question-2: Choose 3 different cells of the musculoskeletal system and describe their structure and function, making links to the maintenance of healthy function in the above scenario

Osteogenic cells are derived from mesenchymal and retain their cytoplasmic extensions and connections to adjacent cells. All bones have several primary ossification centers.

Osteoblasts cell are found at the site of bone formation, close to the bone matrix. They are young cells that create bone. They have a relatively large oval nuclei, containing within a few small nucleoli, a well-developed tight endoplasmic reticulum and Golgi apparatus, which provides a precise orientation of the polarized secretion of matrix. The cells are also joining the "window" for communication with neighboring osteoblasts, and possibly with the osteocytes. Joining the "window" is a small hole between the cells that allow molecules to pass, converting signals, such as calcium etc. Cells are clearly polarized, produce and secrete matrix only on the basal side. By the end of the productive period of osteoblast becomes flat and covers the thin unmineralized matrix, called osteoid.

Osteocytes are flat, thin, elongated bone cells, with a few organelles. They cover the surface of the bone and may mediate the signals that regulate bone resorption. Such connections between the cells could explain the response to tissue nadkletochnom level in the process of bone remodeling (reconstruction).

Osteoclasts cells are multi-core, long before the end of the differentiated cells that are formed through the merger of mononuclear cells of hematopoietic nature. They can destroy cartilage and bone obyzvestlenny. On the side of osteoblast adhesion to the surface of the destroyed distinguish two zones. The first zone - the most extensive, which is called the "brush border" or "crimped edge": it is an area of the secretion of hydrolytic enzymes. The second zone - the zone of dense adhesion to the bone osteoclast surface.
