We then sighted perpendicular to the plane created by the pubic symphysis with the vertex at the intersection of the ischiatic arch and pubic symphysis (Fig.
The angle of the ischiatic arch (angle 1) was the only measurement that definitively identified the sex of an unknown moose.
Angle 1, the ischiatic arch (the most robust sexing technique of the study) was measured with a device that appears cumbersome and difficult to use without proper instruction.
Pelvic bone located parallel to belly; pelvic bone short, straight and sharp; ischiatic
process short, straight, and with two pointed apophyses posteriorly.
In the extrapelvic course of the inferior gluteal artery was observed that one of its branches, called ischiatic artery, is a long and thin vessel that is related to the ischiatic nerve; and that the internal pudendal artery in this region sends only muscular branches to irrigate the muscles of this region (Williams et al.
1994) related that the presence of aneurysms and pseudoaneurysms in these vessels could lead to a compression of the ischiatic nerve causing lumbar and sciatic pains in the patients.
During a dissection of the gluteal region in a 60-year-old male sex corpse, used in practical lessons of various courses of medical area, was observed a variation in the origin and the course of the right ischiatic artery.
On 18 cases it was observed only one innervation branch, coming from the tibial portion of the ischiatic
nerve directed to the semimembranosus muscle and in the remaining 10 cases it was observed that two branches were received by the semimembranosus muscle.
In all cases the nerve branches for the questioned muscle come from the tibial nerve portion of the ischiatic
