An articular capsule (or joint capsule) is an envelope surrounding asynovial joint . [ [http://www.emedicine.com/asp/dictionary.asp?keyword=Articular+capsule eMedicine/Stedman Medical Dictionary Lookup! ] ]Layers
Each capsule consists of two layers:
* an outer layer ("stratum fibrosum") composed of white fibrous tissue
* an inner layer ("stratum synoviale") which is a secreting layer, and is usually described separately as thesynovial membrane .On the inside of the capsule, articular cartilage covers the end surfaces of the bones that articulate within that joint.
The outer layer is highly innervated by the same nerves which perforate through the adjacent muscles associated with the joint.
