Motor innervation to the muscles of facial expression is provided by the
facial nerve (CN VII)
The nerve that is a cutaneous branch of the trigeminal nerve that is responsible for the lacrimal, supra-orbital, supratrochlear, infratrochlear and external nasal nerves
Ophthalmic nerve (CN V1)
The nerve that is a cutaneous branch of the trigeminal nerve that is responsible for the infra-orbital, zygomaticotemporal and zygomaticofacial nerves
Maxillary nerve (CN V2)
The nerve that is cutaneous branch of the trigeminal nerve that is responsible for the auriculotemporal, buccal and mental nerves

Where does facial nerve (CN VII) emerge from the cranium
Stylomastoid foramen
Most arteries supplying the face are branches of the
External carotid arteries
Lymph from the scalp, face and neck drains into the
Superficial ring of lymph nodes
Lymph from the lateral pat of the face and scalp drains to the
Superficial parotid LNs
Lymph from the deep parotid nodes drains to the
deep cervical LNs
Lymph from the upper lip and lateral parts of the lower lip drains to the
Submandibular LNs
Lymph from the chin and central part of the lower lip drains into the
Submental LNs
The largest of the 3 paired salivary glands
Parotid Gland
