4. Trigeminal nerve

9. V1 Opthalmic nerve
 Forehead and scalp
 Frontal and ethmoidal sinus
 Upper eyelid and its conjunctiva
 Cornea
 Dorsum of the nose

11. V2 Maxillary nerve
• Lower eyelid and its conjunctiva
• Cheeks and maxillary sinus
• Nasal cavity and lateral nose
• Upper lip
• Upper molar, incisor and canine teeth and the associated
gingiva
• Superior palate

13. V3 Mandibular nerve -Sensory
• Mucous membranes and floor of the oral cavity
• External ear
• Lower lip
• Chin
• Anterior 2/3 of the tongue (only general sensation;
special taste sensation supplied by the chorda tympani,
a branch of the facial nerve)
• Lower molar, incisor and canine teeth and the associated
gingiva

15. V3 motor
• Muscles of mastication; medial pterygoid, lateral
pterygoid, masseter, temporalis
• Anterior belly of the digastric muscle and the mylohyoid
muscle

22. Miscellaneous – Trigeminal neuralgia

23. FACIAL NERVE

24. Facial nerve
• Motor: Innervates the muscles of facial expression, the
posterior belly of the digastric, the stylohyoid and the
stapedius muscles.
• Special Sensory: Provides special taste sensation to
the anterior 2/3 of the tongue.
• Parasympathetic: Supplies many of the glands of the
head and neck, including the submandibular,
sublingual, nasal, palatine, lacrimal and pharyngeal
gland

27. Facial canal

30. Facial nerve
• Facial nerve course and lesions

39. Motor nerve branches
• Temporal branch – Innervates the frontalis, orbicularis
oculi and corrugator supercilii
• Zygomatic branch – Innervates the orbicularis oculi.
• Buccal branch – Innervates the orbicularis oris,
buccinator and zygomaticus muscles.
• Marginal Mandibular branch– Innervates the mentalis
muscle.
• Cervical branch – Innervates the platysma.
