Hip Anatomy and Ontogeny of Lower Limb Musculature in Three Species of Nonhuman Primates
Figure 7
Articular cartilage in adult cheirogaleids, acetabular (A) and femoral (F) surfaces are shown. Superior aspect is at the top of the image. Arrowheads indicate the junction of the subchondral plate and articular cartilage. (a, b) C. medius (same specimen); (c) M. murinus (2 different specimens). Note the difference in articular cartilage thickness of the acetabulum compared to the femoral head in C. medius (a, b). This is most apparent when viewing the extent of cartilage that is between the tidemark (TM) and the joint cavity (the TM is the line separating the deeper mineralized cartilage matrix from the more superficial matrix.) There is less disparity in articular cartilage thickness between the joint surfaces in M. murinus (c). Ca: joint cavity; Sy: synovial membrane. Stains: a, b: Gomori trichrome preparation; c: Picro Ponceau. Scale bars: a, c, d: 300 μm; b: 200 μm.
