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:"
Squamous part of temporal bone from the external acoustic meatus; it is divided into two parts by a narrow slit, the petrotympanic fissure (Glaserian fissure). The anterior part, formed by the squamous part, is smooth, covered in the fresh state with cartilage, and articulates with the condyle of the mandible. Behind this part of the fossa is a small conical eminence; this is the representative of a prominent tubercle which, in some mammals, descends behind the condyle of the mandible, and prevents its backward displacement. The posterior part of the mandibular fossa, formed by the tympanic part of the bone, is non-articular, and sometimes lodges
