Hemodynamics - Blood and its composition. 1  Blood is a complex liquid. Blood is composed of plasma and formed elements. 2  Normal blood plasma behaves like a Newtonian fluid at physiological rates of shear. 3  The osmotic pressure of solution is determined by the number of particles present and by the temperature.
A synovial joint, also known as diarthrosis, is the most common and most movable type of joint in the body of a mammal. As with most other joints, synovial joints achieve movement at the point of contact of the articulating bones.Structural and functional differences distinguish synovial joints from cartilaginous joints (synchondroses and symphyses) and fibrous joints (sutures, gomphoses, and syndesmoses). Articular cartilage: the bones of a synovial joint are covered by this layer of hyaline cartilage that lines the epiphyses of joint end of bone with a smooth, slippery surface that does not bind them together; articular cartilage functions to absorb shock and reduce friction during movement.
Above: Diagram of the structure of a synovial joint. Synovial joints have a synovial cavity between the articulating bones. This cavity is filled with synovial fluid that reduces friction at the joint, enabling the articulating bones to move freely.The page about types of joints explains the 3 functional classes of joints: 1  synarthroses (immovable joints).ynovial joints are freely movable joints. A formal medical term is  diarthroses  but synovial joints are commonly described as simply  movable  or  freely movable . Most of the main joints of the appendicular skeleton (including the arms and hands, and the legs and feet) are synovial joints.
