(General) somatic sensory function for the face is served primarily by the trigeminal nerve and we considered these structures in detail in Module 4. The view above is just a schematic version of Figure 4-4.

Something we didn't tell you earlier is that during development all the branchial arches share a common turf in the region aroind the ear. Thus cranial nerves 7, 9 and 10 each have a few somatic sensory fibers. For more detail, see descriptions of the individual nerves, later in the module.
