What is in the anatomy of articulation?
In anatomy, articulation concerns the movement of neighboring bones around the joint between them. When used as a noun, articulation is synonymous for the term joint. The example can be seen in acetabulofemoral articulation or hip joint, where the bones of the femur in the thigh articulate with the pelvic bones in the hip. Actions on the joint, as initiated by the muscles that pass it, are what allows movement, and the type of articulation dictates what types of movement are possible in this joint. Specifically, it is the shape of the articulation surfaces of neighboring bones on the joint that determines which movements that the joint can produce. amphartrosis that allow a small degree of movement; and the course that can move in several directions. Syarthroses usually concerns the bones in the head, as in Large Flat Bones skulls, which are held together by a thick fibrous tissue. Amphartrosis include joints between vertebrae and joints between tibia and fibula in the lower leg. They rely on the cartilage to hold the bones together.
Synovial joints are considered "movable" joints. They are distinguished by the lubricating fluid bag inside the joint known as synovial fluid, which minimizes the friction of the bone during movement. The most numerous joints of the body are classified according to the movements they allow. The hinge or gontymium joints allow only flexion and extension or bending and straightening, as in the elbow joint. Swelling or trochoid joints allow rotation, as if two upper vertebrae, atlas and axis turn around to turn the head from side to side.
plane or arthrodial joints allow a slight sliding movetween bones. Examples of this type of joint include cards in the hands and tarsaly in the feet. The condyloid joints, named for the oval shape of neighboring bones, allow a wider range of movement because they have a bony head that is pulled at the end of another bone, for example in the wrist. Movements in this articulation include fleXE and extension, adction and kidnapping or waving your hand from side to side and perimeter or circling of the hand on the wrist.
Two other categories of synovial joint include saddle joints and a ball joint. The joints of the saddle or seller include a thumb joint and characterized by contradictory shapes of neighboring bones that resemble two saddles curved around each other in perpendicular directions as if they were formed X. movements of possible movements, or if it is effect or if it is fold or effect or effect or effect or effect or effect or effect or effect or effect or effect or effect or effect effect, or about the effect, or effect, or if it is composed and thouni.UMB towards the palm of the hand, how to touch the tip of four fingers.
joints with balls and plinths, to see on the hips and shoulders, allow the most full range of movement of all joints of the body. These allow the limb to surround 360 degrees around the joint. All of the above movements are possible in this articulation as wellPusies back and forth in the joint.
