Get answer to your question and much more Introduction[edit | edit source] Joints, also known as articulations, are a form of connection between bones. They provide stability to the skeletal system as well as allowing for specialized movement. Joints can be classified:
Generally speaking, the greater the range of movement, the higher the risk of injury because the strength of the joint is reduced The two classification schemes correlate:
The 5 minute video outlines the basics. Fibrous Joints[edit | edit source]In fibrous joints (synarthrodial joint) the bones are joined by fibrous tissue, namely dense fibrous connective tissue, and no joint cavity is present. The amount of movement allowed depends on the length of the connective tissue fibers uniting the bones. Although a few are slightly movable, most fibrous joints are immovable. The three types of fibrous joints are sutures, syndesmoses, and gomphoses.
Cartilaginous Joints[edit | edit source]Cartilaginous joints are a type of joint where the bones are entirely joined by cartilage, either hyaline cartilage or fibrocartilage. These joints generally allow more movement than fibrous joints but less movement than synovial joints.
Synovial Joints[edit | edit source]The primary purpose of the synovial joint is to prevent friction between the articulating bones of the joint cavity. While all synovial joints are diarthroses, the extent of movement varies among different subtypes and is often limited by the ligaments that connect the bones. Nearly all joints of the limbs and most joints of the body fall into this class. A key structural characteristic for a synovial joint that is not seen at fibrous or cartilaginous joints is the presence of a joint cavity. The joint cavity contains synovial fluid, secreted by the synovial membrane (synovium), which lines the articular capsule. This fluid-filled space is the site at which the articulating surfaces of the bones contact each other. Hyaline cartilage forms the articular cartilage, covering the entire articulating surface of each bone. The articular cartilage and the synovial membrane are continuous. A few synovial joints of the body have a fibrocartilage structure located between the articulating bones. This is called an articular disc, which is generally small and oval-shaped, or a meniscus, which is larger and C-shaped.[1] See Synovial Joint Link for full explaination. Physiotherapy[edit | edit source]Physiotherapists are qualified health care professionals who are experienced at assessing joints of the human body. See links to below conditions for some examples.

What type of joint is between the carpal and the first metacarpal?The carpometacarpal joints of the fingers are synovial plane joints that serve as the articulation between the carpals and the metacarpals and allow the bases of the metacarpal bones to articulate with one another.
What type of joint is between trapezium and metacarpal?The first carpometacarpal joint of the thumb is particularly important; the articulation between the first metacarpal and the trapezium bone forms a saddle joint and allows a wide range of movement, including flexion, extension, abduction, adduction, circumduction and opposition of the thumb.
What type of joint is the carpometacarpal joint of the 1st digit of the hand?The 1st CMC (carpometacarpal) joint is a specialized saddle-shaped joint at the base of the thumb. The trapezium carpal bone of the wrist and the first metacarpal bone of the hand form the 1st CMC or thumb basal joint.
