第 45 題
鼠蹊部疝氣(inguinal hernia)為兒童常見的外科疾病,了解疝氣腹壁解剖學相關知識對於手術執行極為重要。下列有關鼠蹊部疝氣解剖學,何者敘述正確?
- A 間接型鼠蹊疝氣(indirect inguinal hernia)經由腹壁下動脈(inferior epigastric artery)內側突出於腹壁,多發生於兒童
- B 髂腹下神經(iliohypogastric nerve)走於精索(spermatic cord)之上,與精索一齊穿出外鼠蹊環(external inguinal ring),負責大腿內側上方的感覺
- C 提睪肌(cremaster muscle)是由腹內斜肌(internal oblique muscle)延伸而來
- D 睪丸動脈(testicular artery)源自內髂動脈(internal iliac artery)
思路引導 VIP
請思考在腹股溝區域(inguinal region)的解剖層次中,腹壁的各層肌肉與筋膜(例如腹外斜肌、腹內斜肌、腹橫筋膜)分別演化成精索(spermatic cord)的哪些被蓋(coverings)構造?特別是腹內斜肌在向下延伸進入陰囊的過程中,與哪一個負責提睪反射的解剖構造具有胚胎來源的延續性?
