胸管（thoracic duct）和下列那一構造一起穿過橫膈膜進入胸腔？

下腔靜脈 食道 主動脈 迷走神經

下列有關顏面神經的敘述，何者正確？

運動根（motor root）含有副交感神經纖維

中間神經（nerve intermedius）含有支配軟腭的感覺神經纖維

岩大神經（greater petrosal nerve）含有支配骨骼肌的運動神經纖維

味覺纖維的細胞本體位於膝狀神經節（geniculate ganglion）

D

The nervus intermedius, or intermediate nerve, is the part of the facial nerve (cranial nerve VII) located between the motor component of the facial nerve and the vestibulocochlear nerve (cranial nerve VIII). It contains the sensory and parasympathetic fibers of the facial nerve. Upon reaching the facial canal, it joins with the motor root of the facial nerve at the geniculate ganglion.

The greater (superficial) petrosal nerve is a nerve in the skull that branches from the facial nerve; it forms part of a chain of nerves that innervates the lacrimal gland. The fibres have synapses in the pterygopalatine ganglion.

下列何者不發生於近距離之調焦作用（accommodation）？

第三對顱神經副交感節前纖維興奮

睫狀肌（ciliary muscle）收縮

水晶體懸韌帶（suspensory ligaments of lens）被拉緊

水晶體變凸變厚

下列有關翼腭窩（pterygopalatine fossa）之敘述，何者錯誤？

上頜動脈（maxillary artery）之第三部分進入此窩

由翼腭窩向內經鼻腭孔（nasopalatine foramen）進入鼻腔

上頜神經（maxillary nerve）經過此窩

此窩中之副交感神經節前纖維來自翼管（pterygoid canal）

B

Passages

The following passages connect the fossa with other parts of the skull:

Direction	Passage	Connection
Posteriorly	foramen rotundum	middle cranial fossa
Posteriorly	pterygoid canal (Vidian)	middle cranial fossa, foramen lacerum
Posteriorly	palatovaginal canal (pharyngeal)	nasal cavity/nasopharynx
Anteriorly	inferior orbital fissure	orbit
Medially	sphenopalatine foramen	nasal cavity
Laterally	pterygomaxillary fissure	infratemporal fossa
Inferiorly	greater palatine canal (pterygopalatine)	oral cavity, lesser palatine canals
