facial (VII)
The mandibular nerve (V3) moves away from the brain by means of three foramina: the _____, then the _____, and finally the _____.
foramen ovale, mandibular foramen, mental foramen
This foramen is in the spenoid bone and is the first foramen that the maxillary nerve passes through as it leaves the cranium.
foramen rotundum
The maxillary (V2) nerve moves away from the brain by means of three foramina: the _____, then the _____, and finally the _____.
foramen rotundum, inferior orbital fissure, infraorbital foramen
The _____ is the cranial nerve that has parasympathetic neurons that control the parotid salivary gland.
glossopharyngeal (IX)
The _____ nerve motor to stylopharyngeus muscle, sensory to the posterior 1/3 of the tongue (general senses and taste), pharynx, a branch to carotid sinus, as well as parasympathetic neurons to the parotid gland.
glossopharyngeal (IX)
The _____, _____, and _____ nerves as well as the _____ (vessel) pass through the jugular foramen to exit the skull cavity.
glossopharyngeal (IX), vagus (X), spinal accessory (XI), internal jugular vein
This cranial nerve is found in the anterior triangle of the neck. It runs with an artery that has a different name, but their names translate to the same meaning. It is a motor nerve.
