A broad accumulation of stratified drift deposited adjacent to the downstream edge of an end moraine is a(n) ________. During the most recent ice age, glaciers covered about ________ percent of Earth's land area. The most abundant chemical sedimentary rock is ________.
The distal end of the femur articulates with the tibia in the lower leg and the patella or knee cap. The tibia below does not articulate with the patella. Between the condyles is the patellar surface that articulates with the patella or knee cap. These landmarks are important attachments for ligaments and muscles which will be discussed later in this unit. Another important anatomical component of the knee are the menisci.
Definition. Chondromalacia patella is a softening or wearing away of the articular cartilage on the undersurface of the kneecap (patella). Articular cartilage is a smooth substance that covers the femur (thighbone), the tibia (shinbone), and the patella. These structures form the knee joint.
