EMPHYSEMA Emphysema ( Greek : emphysan : inflate Itself composed of en meaning in and physan   meaning breath, blast)  Emphysema means swelling. Emphysema is included in a group of the disease called chronic obstructive pulmonary disease (COPD). It is often caused by long term exposure to air pollution or smoking. Emphysema causes dilation of air spaces by the destruction of the alveolar wall, leading to the collapse of alveoli during expiration. Emphysema is a long-term progressive disease of the lungs that primarily causes shortness of breath. There is the destruction of lung tissue around smaller sacs, called alveoli, which makes their air sacs unable to hold their functional shape upon exhalation. That is why it is called obstructive lung disease. ETIOLOGY 1)Tobacco smoking 2) Atmospheric pollution 3) Infections 4) Genetic factor 5) Alpha-1 antitrypsin deficiency 6) Inherited diseases (rare) [ Marfan syndrome, Menke's syndrome] 7) Severe cases of Alpha I a...

Anatomy of bone

By
 Anatomy of bone Bone is the hardest part of the body which is covered by muscle. Classification of bone Long bone Short bone Flat bone Irregular bone Let's discuss the structure of the typical long bone In children, a typical long bone lets take an example of the femur has 2 ends which are also known as epiphyses, and an intermediary portion called the shaft, which is also known as diaphysis. The part of the shaft which joins the epiphyses is called metaphysis. Epiphyses and metaphyses are separated by a  thin plate of growth cartilage, one at each end. This plate is known as the epiphyseal plate. At maturity, the epiphyses are fuses with the metaphysis. The epiphyseal plate gets replaced by bone. Articular cartilage covers the articular ends of the epiphyses. Periosteum covers the rest of the bone and it provides attachment to the tendons, muscles, ligaments, etc. Sharpey's fibres are present which connects the bone to the periosteum & they are  the str...
