. The comparative anatomy of the domesticated animals. Veterinary anatomy. AETICULATIOXS OF TEE POSTERIOR LUIBS. 167 they will not be detailed here; but some remarks will be made with regard to the displacement the tibro-cartilages undergo when the articulation is in motion. During flexion and extension, tliese bodies, fixed on the tibial facets, which they transform into glenoid cavities, move with them on the condyles of the Fig. 92. femur, from before to behinil,or behind ^*'- 1- ^o. 2. to before, according to the movement executed. But at the same time they also gli<le in an inverse direction, and to a very appreciable degree, on the superior extremity of the tibia. There- fore, during flexion, they pass from behind forward on this extremity, and are drawn backwards during exten- sion. In rotation, which may take place from within to without, or from with- out to within, the movement is pro- duced not only by the pivoting of the condyles in their glenoid cavities, but also by a sensible displacement of the meniscii on the tibial surfaces. In the Bog and Cat, the meniscii are joined together near their anterior insertion by a transverse fibrous baud. There is only one patellar ligament, and the posterior liga- ment shows in its thickness two small sesa- moid bones against which the condyles of the femur play inwardly, and which give attachment, outwardly, to the originaiing branches of the external gastrocnemius mus- cle. There is no femoro-pati^lar capsule, and only one sjTiovial membrane for the whole articulation. In the Pig and Sheep, there is also only one ligament and one synovial Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Chauveau, A.
