Question

唾液腺的分泌活動(dòng)受到下列哪些神經(jīng)支配（多選）？（    ）

       A．第Ⅶ對(duì)腦神經(jīng)                       B．交感神經(jīng)

       C．第Ⅸ對(duì)腦神經(jīng)        D．舌下神經(jīng)           E．三叉神經(jīng)

Answer 1

ABC

解析:

第Ⅶ對(duì)腦神經(jīng)為面神經(jīng)，第Ⅸ對(duì)腦神經(jīng)為舌咽神經(jīng)，含副交感神經(jīng)纖維，使唾液分泌物稠厚。交感神經(jīng)使唾液分泌物稀薄。
