Gluteal region Sciatic nerve and other gluteal structures of the right side

右侧臀区坐骨神经和其他臀部结构图

Most of gluteus maximus (1) has been removed (as have the veins that accompany arteries) to show the underlying structures, the most important of which is the sciatic nerve (14 and 15). The key to the region is the piriformis muscle (2): the superior gluteal artery (3) and nerve (4) emerge from the pelvis above piriformis, while all other structures leave the pelvis below piriformis. Apart from the sciatic nerve (14 and 15), these include the inferior gluteal nerve (6) and artery (22) and the posterior femoral cutaneous nerve (16).

大部分臀大肌(1)已被切除(伴随动脉的静脉也已切除)以显示底层结构，其中最重要的是坐骨神经(14和15)。该区域的关键是梨状肌(2):臀上动脉(3)和神经(4)起源于梨状肌上方的骨盆，而所有其他结构都离开梨状肌下方的骨盆。除了坐骨神经(14和15)，这些包括臀下神经(6)和动脉(22)和股后皮神经(16)。
