App1 Essay - Bone Cells

In relation to the osseous organisation:
a.Outline the mental synthesis and function of the main types of cells embed in bone.
b.Outline the cause of the aging process in the mature skeletal system using osteoarthritis to support your answer.

A system is a group of organs arranged to poseher to perform special(prenominal) functions. The skeletal system is made up of organs (206 bones) and colligation tissues such as cartilage, ligaments and joints. This forms a framework to provide the proboscis with support, protection and movement (Thibodeau & Patton, 2005). In the bone there atomic number 18 a number of cells; osteogenic cells, endosteal lining cells (bone lining) and osteoprogenitor cells (Väänänen, Zhao, Mulari & Haleen, 2000).

This part of the leaven focuses on the osteogenic cells, which are comprised of osteoblasts, osteoclasts and osteocytes; the main organelles present within these cells and how their dainty ultrastructure enable them to carry out their specialised functions within the skeletal system.

Osteoblasts are bone forming cells which develop from young osteoprogenitor cells. They are found in the hard calcified structure of the periosteum, at the site of rive and at the at the ends of the diaphysis of long bones.



Osteoblasts secrete an natural collagen matrix containing mostly type I collagen, called osteoid (Waugh & Grant, 1996). Structurally, osteoblasts are naughty in rough endoplasmic reticulum, ribosomes and golgi apparatuses. This combination of organelles is concerned with the synthesis of proteins such as the collagen required to lubricate and maintain bone joints (Väänänen et al., 2009). Rough endoplasmic reticulum process new proteins such as fibrous collagen, whilst ribosomes translate single strand ribonucleic acid into proteins which are sorted and modified into proteins by the golgi apparatus. The energy producing mitochondria are intrinsic to the maintenance of the cell as this organelle ensures that the protein, collagen, is synthesised and osteiod is...If you want to get a full essay, order it on our website: Orderessay
