The Skeletal System

The skeletal system includes connective tissue that stabilizes or interconnects the bone tissue of the body and various bones. Bones are dynamic tissues. Throughout the lifecycle, bone can adapt to the physiological and mechanical needs of growth and remodeling processes. As a system, by providing a firm attachment to the bone and acting as a lever system to amplify small movements, it supports the load without deformation, effectively maintaining posture and maintaining posture I can.

Motor mechanisms include three major systems of nervous system, muscular system, and skeletal system. The nervous system emits an electrical impulse that activates the muscles and provides a lever and anchor to pull the muscle. Every skeletal muscle has a starting point and an insertion point. The starting point is an anchor, while the muscles are functioning, the bones remain stationary. Insertion is a moving bone as muscles function. Thus, for example, in the case of the biceps brachialis muscle, the upper arm and shoulder are the starting point (anchor) and the forearm bone is the insert. Interestingly, the strength required by the muscles is directly related to the length of the bone (or lever) and the place where it is attached. This means that the person with a lower height than the one with a stature has a shorter length of bone to use and the connection point is close to the origin, so that the power actually used is small.

All the bones and joints in the body form a skeletal system, which essentially combines with the muscles to form the musculoskeletal system. The skeletal system has three basic functions. As explained in Chapter 3, the skeletal system supports all other organ systems in the body by providing the inner and outer bone and joint frameworks of other organ systems. This structure also provides the shape of the body. Bones can protect internal organs such as the brain, lungs, uterus. This is a noteworthy feature, therefore worthy of detailed processing.

People have skeletal systems of more than 200 bones. In fact, if you want to know, the exact number of adults is 206. In this lesson we will explain how to organize these bones and other connective tissues into a skeletal system to shape the body and protect important organs. We will also explain how the muscular system and the skeletal system and the muscular system work together in order to enable human movement and physical ability. A human being has an endoskeletal body inside the body. Remember that most human bones are composed of bones and are composed of mineralized calcium phosphate that is secreted into the extracellular matrix by bone cells called bone cells. Human bones also contain considerable cartilage
