Nasalis Muscle
Zygomatic Branch of Facial Nerve CN VII
Frontalis Muscle
Frontalis part - Temporal Branch of Facial Nerve CN VII
Occipital part - Posterior Auricular Branch of Facial Nerve CN VII
Nerve that is sensory component for all sensation over the face
Trigeminal Nerve CN V
V1 division of Trigeminal Nerve
V1 Ophthalmic
V2 division of Trigeminal Nerve
V2 Maxillary
V3 division of Trigeminal Nerve
V3 Mandibular
Branches of V1
- Supraorbital
- Supratrochlear
- Infratrochlear
- External nasal
- Lacrimal
Branches of V2
- Infraorbital
- Zygomatico Facial
- Zygomatico Temporal
- Superior Alveolar
Branches of V3
- Auriculotemporal
- Buccal
- Inferior alveolar
- Lingual
The Facial Nerve emerges from the base of the skull through…
Stylomastoid foramen, and then branches after they pass through parotid gland
Branches of Facial Nerve, CN VII
- Cervical
- Mandibular
- Buccal
- Zygomatic
- Temporal
- Posterior Auricular
Facial Vein drains into….
Internal Jugular Vein
Retromandibular vein drains into…
External Jugular Vein & Facial Vein
Veins around the nose…
Continuous with veins in orbit that drain into cranial cavity
—this is a source of infections to the meninges and brain
Parotid Gland can be found where
Wedged between ear and posterior edge of ramus of mandible
Parotid Duct can be found where
Below the zygomatic arch & empties into the oral cavity
What nerve travels through the Parotid gland but does not innervate it
Facial Nerve
What innervates the Parotid Gland
Glossopharyngeal Nerve (CN IX)
What nerves lies deep to the Parotid Gland
Auriculotemporal Nerve
—Branch of V3
Clincial correlations associated with all this junk
- Bell’s Palsy
- Trigeminal Neuralgia
- Herpes Zoster (shingles)
- Cancer of the parotid gland
