The musculoskeletal system provides form, support, stability, and movement to the body. The human skeleton has 206 bones, which begin to develop before birth. When the skeleton first forms, it is made of flexible cartilage, but within a few weeks it begins the process of ossification. Ossification is when the cartilage is replaced by hard deposits of calcium phosphate and stretchy collagen, the two main components of bone. It takes about 20 years for this process to be completed.This system describes how bones are connected to other bones and muscle fibers via connective tissue such as tendons and ligaments.The bones provide the stability to a body in analogy to iron rods in concrete construction. Muscles keep bones in place and also play a role in movement of the bones.There are three types of muscles: skeletal, smooth, and cardiac (heart). Two of these kinds—skeletal and smooth—are part of the musculoskeletal system.
Anti Rheumatics
Antirheumatics include drugs, which are used to treat the symptoms of rheumatoid arthritis and those that can modify the course of the disease. The drugs that help treat the symptoms such as pain and inflammation are aspirin, non-steroidal anti-inflammatory drugs (NSAIDs) and steroids. Drugs that can slow the progression of rheumatoid arthritis and help with pain, inflammation and stiffness are called disease modifying rheumatoid arthritis drugs (DMARDs).
