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.
Anatomy: The bones in the knee joint comprise the thigh bone (femur), shin-bone (tibia) and the knee cap (patella). The articular surfaces of the thigh bone, shin-bone and knee cap are lined with a cartilage covering of a few millimetre's thickness which serves to reduce the load or strain on the joint surfaces. Patella.
