Each capsule consists of two layers or membranes: an outer (fibrous membrane, fibrous stratum) composed of avascular white fibrous tissue; an inner (synovial membrane, synovial stratum) which is a secreting layer; On the inside of the capsule, articular cartilage covers the end surfaces of the bones that articulate within that joint.
During pregnancy it is also produced by the placenta, chorion, and decidua. The body produces relaxin during menstruation that rises to a peak within approximately 14 days of ovulation and then declines. In pregnant cycles, rather than subsiding, relaxin secretion continues to rise during the first trimester and then again in the final weeks.
Photos of what pregnancy tissue from early abortions at 5 to 9 weeks actually looks like have gone viral.. The images, which were originally shared by MYA Network — a network of physicians who ...
The articular capsule of the knee joint is the wide and lax joint capsule of the knee. It is thin in front and at the side, and contains the patella, ligaments, menisci, and bursae of the knee. [1] The capsule consists of an inner synovial membrane, and an outer fibrous membrane separated by fatty deposits anteriorly and posteriorly. [2]
The hardening of the shoulder joint capsule is central to the disease process. This is the result of scar tissue around the joint capsule. [14] There also may be a reduction in synovial fluid, which normally helps the shoulder joint, a ball and socket joint, move by lubricating the gap between the humerus and the socket in the shoulder blade.
In contrast to the volar plates of the MCP joints of the fingers, the volar plate of the thumb MCP joint is a thick structure firmly attached to the base of the proximal phalanx. It forms the bottom of a two-sided box, the sides of which are made up of the collateral ligaments .

A gomphosis, also known as a dentoalveolar syndesmosis, [11] or 'peg and socket joint' [12] is a joint that binds the teeth to bony teeth sockets in the maxillary bone and mandible. Gomphos is the Greek word for "bolt". The fibrous connection between a tooth and its socket is a periodontal ligament. Specifically, the connection is made between ...
