Dog anatomy rotate the pelvic limb laterally. It is innervated by the sciatic nerve. Gemelli: originates on the lateral surface of the ischium and inserts on the trochanteric fossa. It acts to rotate the pelvic limb laterally. It is innervated by the sciatic nerve. Quadratus femoris: originates on the ischium and inserts on the intertrochanteric crest. It acts to extend the hip and rotate the pelvic limb laterally. External obturator: originates on the pubis and ischium and inserts on the trochanteric fossa. It acts to rotate the pelvic limb laterally. It is innervated by the obturator nerve. "Cranial muscles of the thigh:"
Petrous part of the temporal bone petrosal sinus, and gives attachment to the tentorium cerebelli; at its medial extremity is a notch, in which the trigeminal nerve lies. The posterior angle is intermediate in length between the superior and the anterior. Its medial half is marked by a sulcus, which forms, with a corresponding sulcus on the occipital bone, the channel for the inferior petrosal sinus. Its lateral half presents an excavation — the jugular fossa — which, with the jugular notch on the occipital, forms the jugular foramen; an eminence occasionally projects from the center of the fossa, and divides the foramen into two.
