Cutaneous innervation of the head
Sensory areas of the head, showing the general distribution of the three divisions of the fifth nerve.
Cutaneous innervation refers to the area of the skin which is supplied by a specific nerve.
Modern texts are in agreement about which areas of the skin are served by which nerves, but there are minor variations in some of the details. The borders designated by the diagrams in the 1918 edition of Gray's Anatomy, provided below, are similar but not identical to those generally accepted today.
The cutaneous innervation of the head is as follows:
- Ophthalmic nerve (green)
- Maxillary nerve (pink)
- Mandibular nerve (yellow)
- Cervical plexus (purple)
- Dorsal rami of cervical nerves (blue)
