Document Summary
Sensory nerve to cornea, teeth, skin and mucosa of nasal and paranasal sinuses + oral cavity. All of these foraminae: all in the sphenoid lateral three of the branches of the trigeminal nerve and the mandibular nerve: Can see the: maxillary nerve is coming from the foramen rotundum into the mouth via the pterygoid fissure. Everything else is from spinal nerves: greater and lesser occipital + 3rd nerves = skin of. Test areas of jaw, cheek, forehead by cotton ball and a blunt end of a stick. You can check the corneal reflex: as the trigeminal nerve supplies sensory nerves to the cornea via ophthalmic nerve: touch cornea with eyeball, therefore the person will blink (afferent: cnv1, efferent: cnviii) Facial nerve: motor nerve to muscles of facial expression + scalp: Special sensory fibres to the anterior 2/3 of tongue: general sensory from skin of external acoustic meatus, visceral motor (parasympathetic) to salivary, lacrimal and nasal glands (not parotid)
