: More Questions on Subinguinal Region:
: 1. Define the superior, middle, and inferior cluneal nerves - and indicate where they supply innervation cutaneously. These nerves arise from L1 through S3. The superior cluneal nerve innervates the skin of the superior portion of the buttock, the middle cluneal nerves innervate the middle part of the buttock cutaneous tissue, while the inferior cluneal nerves innervate the skin of the inferior portion of the buttock and the inferior boundary of the gluteus maximus.
: 6. What is the origin and course of the great saphenous vein? Dorsal venous arch is the origin. On the medial side, where it then wraps anterior to the medial mallelous. The vein then goes superiorly, wrapping posterior to the medial condyle of the femur... someone else can take it laterally to saphenous opening where it dives deep through the cribiform fascia (superificial fascia).
