Joints Articulations A joint is any place in your body where two bones meet. they’re part of your skeletal system. you might see joints referred to as articulations. you have hundreds of joints throughout your body, and many ways healthcare providers group them together (classification). joints are usually classified based on: their function: how they move. The specific anatomic features of a joint play a large role in determining its range of motion, degrees of freedom, and overall functional potential. this chapter is intended to provide an overview of the basic structure and function of joints as a foundation for understanding the motion of individual body segments and the body as a whole.
Ppt Joints Powerpoint Presentation Free Download Id 2207087 A joint, also known as an articulation, is a location where two or more bones meet. most joints contain a single articulation. each articulation contains the names of two bones (or sockets). for example, the hip joint is known as the acetabulofemoral joint since it is where the acetabulum ("acetabulo ") of a coxal bone articulates with the head. A condyloid joint (ellipsoid joint) is an articulation between the shallow depression of one bone and the rounded structure of one or more other bones. this joint type is biaxial, permitting movement in 2 axes. thus, 4 movements are possible at condyloid joints: flexion, extension, abduction, and adduction. An examples of this is the radio ulnar articulation which allows for pronation (palm down) and supination (palm up) of the forearm. saddle joints: the only saddle joints are in the thumb. ball and socket joints: bones of these joints fit together like a ball in a socket i.e. the round end of one bone fits into the concave socket of the other bone. Joint. the knee joint provides flexion to the legs and absorbs some of the force of running and walking. joints hold the skeleton together and support movement. there are two ways to categorize joints. the first is by joint function, also referred to as range of motion. the second way to categorize joints is by the material that holds the bones.

Cartilaginous joints. cartilaginous joints are chiefly characterized by the fact that they connect with neighboring bones via cartilage. they exhibit a range of motion that falls between synovial and fibrous joints. there are two types of cartilaginous joints, synchondrosis and symphysis joints. sternochondral joints. These joints usually have a wide range of motion, which is defined by the joint capsule, the supporting ligaments and muscles that cross the joint. examples of synovial joints include the knee, shoulder, sternoclavicular and elbow joints. fibrous joints are the articulations in which the bones are connected by dense fibrous connective tissue.
