Human Stage14-16 CN5
This is largest of all the cranial nerves during early development and has three major branches: ophthalmic nerve (V1), maxillary nerve (V2), mandibular nerve (V3)
Note this image has been flipped horizontally (to left view) to use in comparison with other stages.
It is really the right lateral view of the central nervous system of embryo at Carnegie stages 14 and 16.
Scale bar is 1 mm
Mixed motor/sensory
- sensory - provide tactile, proprioceptive, and nociceptive afference to the face and mouth.
- motor - innervate the skin of the face via ophthalmic (V1), maxillary (V2) and mandibular (V3) divisions. Special visceral efferent (SVE) axons innervate the muscles of mastication via the mandibular (V3) division.
