坐骨神经是人体最粗大的神经，起始于腰骶部的脊髓，途经骨盆，并从坐骨大孔穿出，抵达臀部，然后沿大腿后面下行到足。管理下肢的感觉和运动，由腰神经和骶神经组成。 警告：请在有WIFI的场所观看视频，土豪请随意。 The sciatic nerve is the longest and largest nerve in the human body, running from the lower back through the back of the leg, and down to the toes. 坐骨神经是人体最长最大的神经，从腰部发出经腿后方到达足趾。 The sciatic nerve starts as a collection of nerve fibers in the lower spine. These nerve fibers, or roots, exit the spinal canal through a number of openings in the bones at each level of the lower spine called foramen. 坐骨神经起始部是多根腰椎神的纤维集合起来的，这些神经纤维或神经根，从每节腰椎称为椎间孔的开口处自椎管内发生。 These lumbar nerve roots then combine to form one large nerve. The sciatic nerve is about as thick as a man's thumb at its largest point. 然后这些腰神经根形成一根粗大的神经。在最粗的地方，坐骨神经大约有人的拇指那么粗。 The sciatic nerve travels through an opening in the pelvis called the greater sciatic foramen, and typically runs below the piriformis muscle. This is why piriformis muscle problems or spasm can lead to leg pain sciatica symptoms. 坐骨神经经过骨盆上称为坐骨大孔的开口，通常走行于梨状肌的下方，因此梨状肌的疾患或痉挛或导致与坐骨神经痛症状相似的腿痛。 The sciatic nerve then travels down the back of the upper thigh. 此后坐骨神经沿大腿后侧下行。 Above the back of the knee, the sciatic nerve divides into two nerves, the tibial and the common peroneal nerve, both of which serve the lower leg and foot. 在膝关节后上方，坐骨神经分成两条神经，胫神经和腓总神经，它们都支配小腿和足。 Certain conditions in the lower back can irritate the sciatic nerve, causing pain to radiate along the nerve. These symptoms are called sciatica, or lumbar radiculopathy. 腰椎的某些病变会刺激坐骨神经，引起疼痛并沿着神经放射，这些症状称为坐骨神经痛，或腰椎神经根病。 The complex anatomy of the sciatic nerve means that symptoms of sciatica vary depending on where this irritation occurs. 坐骨神经复杂的结构意味着坐骨神经痛的症状因所受累部位的不同而有所不同。 （胡佰文 译） 精彩视频魅力无限，收藏转发一起分享 您的每一次打开，都会有精彩的内容 您的每一次留言，都会有满意的答复 您的每一次点赞，都是对我们的肯定 您的每一次分享，都是对我们的鼓励 世界多姿多彩 感谢有您相伴 |
