Nature ingeniously thought out the human body, there is nothing superfluous in it, and each part of it performs its specific function. Bones are one of the components of the human body. They are arranged in a strictly defined order and serve as a support for the organs and levers to which the muscles are attached. In order for a person to be able to perform various kinds of movements as efficiently as possible, the bones need to be connected to each other.
What is the name of the movable connection of bones, every schoolchild knows, because it is studied in the lessons of human biology. In total, there are three types of bone connections - these are movable, they are called joints, semi-movable, or semi-joints, and the third option is when the bones are fixed to each other. Movable connection - in the shoulder, elbow, wrist, hip, knee, ankle and finger joints. In order for the joint to function, there is a head and a glenoid cavity, which corresponds to it as much as possible. The surface of the bone is covered with cartilage, and inthe joint cavity itself has a special fluid.
Everyone knows the name of the movable connection of bones, but not everyone knows how the joints function properly. This information can be useful not only for doctors or medical professionals, but also for athletes or just a person who is interested in their he alth. The ligamentous apparatus is involved in the formation of the joint, and the capsule covering it provides additional protection. The capsule also serves as a source of secretion of the joint fluid, due to which the cartilage is nourished and glided.
Some joints have little range of motion, and the load on them is much less. The question arises: what is the name of the movable connection of the bones in this case? The answer is simple. Such joints are called semi-movable, or semi-joints, they are located between the vertebrae and in the pubic symphysis. The semi-joint has cartilage and a cavity with a small amount of fluid, but the movements in it are minimal, which distinguishes this type of connection from the rest.
It is possible to move around different axes in the joints, and in each of them the number of axes of rotation is different. In this regard, the joints are divided into uniaxial, biaxial and triaxial. The last option is characterized by the ability to perform the most complex movements.
The question of what the movable connection of bones is called seems to have become clear, but it is worth paying attention to the fact that there are other options with which the bonesconnect with each other. An example of a continuous connection of bones is the skull, the bones of which are fastened together with sutures. Nature has specifically provided for this type of connection of bones to protect important organs, one of which is the brain. Between the bones of the skull there is a very thin layer of connective tissue, which reinforces the continuous connections of the bones of the skull. Another interesting continuous connection should be called driving. This is how teeth connect with bones in our body: they are, as it were, driven by their roots into the bone tissue of the upper and lower jaws and additionally strengthened with the help of ligaments.
Joints have a complex anatomical structure, due to this a person can move. It is important to remember that it is worth starting to take care of the joints from a young age, and then the joy of movement will not be overshadowed by pain and other discomfort.
