Show 878 MR. ST. GEORGE MIVART ON THE [Dec. 6, tiguous to it behind, and the ilio-peroneal in front. It is inserted into the postero-external side of the great trochanter, immediately in front of the insertion of part of the femoro-caudal, and conterminous with the hinder border of the gluteus primus. Gluteus tertius (fig. 1 7, -D3). A small and delicate muscle, which I thus distinguish, arises from a small portion of the lowest part of the posterior margin of the ilium, beneath the origin of the gluteus secundus. It is inserted into the outer side of the great trochanter, just below the insertion of the last-named muscle, and conterminous with the upper end of the insertion of the gluteus primus. Pectineus ? A very small and delicate muscle lies hidden between tbe gluteus tertius and the insertion of the iliacus. It arises, just behind the brim of the pelvis, from the lowest part of the outer side of the ilium, below the origin of the gluteus primus. It is inserted into the outer side of the upper part of the femur, beneath the gluteus tertius, of which, indeed, it m a y be but an accessory portion. Front view of right thigh. C Crureus. D\ Gluteus primus. F1, F2, & F3. Rectus femoris. /. Iliacus. 0. Obturator externus. Adductor (figs. 19, 23, & 24, A). This thick muscle arises from the pelvis, at and near the ischiatic symphysis. Passing down, it is inserted into rather the outside of the shaft of the femur, below the insertion of the femoro-caudal and below and outside the insertions of the obturators. It is obscurely divided into a longer and more slender posterior part, and a thicker, shorter, more anterior portion. |
