Nivelkuoppaa
Nivelkuoppa, a Finnish term for the joint socket, denotes the concave depression on a bone that receives the head of a partnering bone to form a synovial joint. The socket is typically lined with articular cartilage and surrounded by a fibrous joint capsule and ligaments, with synovial fluid inside to reduce friction and nourish the joint surfaces.
Common examples of nivelkuoppa include the glenoid fossa (glenoid cavity) of the scapula, which forms the socket
Socket depth and geometry affect stability and range of motion. Deeper sockets, such as the acetabulum, provide
Development and clinical relevance: nivelkuoppat form during skeletal growth through bone remodeling and growth plate activity.
