The zygomatic nerve is a branch of the maxillary nerve, itself a branch of the trigeminal nerve (CN V). It plays a role in sensory innervation to parts of the face.
Details about the Zygomatic Nerve
Here's a breakdown of key aspects of the zygomatic nerve:
-
Origin: The zygomatic nerve branches off from the maxillary nerve within the pterygopalatine fossa.
-
Course: After originating, it enters the orbit (eye socket) through the inferior orbital fissure.
-
Branches: Within the orbit, the zygomatic nerve divides into two terminal branches:
- Zygomaticotemporal nerve: Provides sensory innervation to the skin over the temple.
- Zygomaticofacial nerve: Provides sensory innervation to the skin over the zygomatic bone (cheekbone).
| Feature | Description |
|---|---|
| Origin | Maxillary nerve (branch of trigeminal nerve CN V) in the pterygopalatine fossa |
| Pathway | Enters the orbit through the inferior orbital fissure |
| Terminal Branches | Zygomaticotemporal nerve (temple skin), Zygomaticofacial nerve (cheekbone skin) |
| Function | Sensory innervation to specific regions of the face (temple and cheek) |
