Innervated by CN VII
Also name the exact nerve branches that innervate these.
- Occipitofrontalis, frontal belly - innervated by temporal branch of VII.
- Occipitofrontalis, occipital belly - innervated by posterior auricular branch of VII.
Also, what is the action of the muscle?
- Long buccal branch of V3 (sensory!)
- Buccinator - it keeps food in your mouth.

- Ophthalmic veins
- Supraorbital veins
What did #1 arise from?
- Supraorbital vessels (the artery came from the ophthalmic artery, a branch of the ICA)
- Transverse facial vessels
- Facial vessels
- Superficial temporal vessels
What is the clinical significance of this setup?
- Superior and inferior ophthalmic veins
- Cavernous sinus
- Pterygoid plexus
Infection on the face (the danger triangle) can travel through the cavernous sinus –> dural sinuses and infect the brain.
What is this triangle called? Where can an infection go from within this triangle?
Danger triangle. Infection can go to cavernous sinus –> dural sinuses and infect the brain.
Into which nodes to these drain?
- Occipital nodes
- Mastoid nodes
- Parotid nodes
- Buccal nodes
- Submandibular nodes
- Submental nodes
- Deep cervical nodes - they all drain to these
Also, which cranial nerve are these branches of?
- Posterior auricular branch
- Stylomastoid foramen
- Temporal branch
- Zygomatic branch
- Buccal branch
- Mandibular branch
- Cervical branch
CN VII
Two Zebras Bit My Cat Posteriorly
Also, what large structure has been cut away?
- Auriculotemporal nerve
- Retromandibular vein
The parotid gland is missing.
What happened?
Mumps, a viral disease that spreads through saliva. Parotid gland is swollen
