1How do the segmental head nerves differenciate from segmental trunk nerves
Similar to segmental trunk nerves except
- autonomic efferent neurones leave via [blank_start]dorsal[blank_end] root rather than [blank_start]ventral[blank_end] root
- dorsal and ventral roots dont [blank_start]unite[blank_end]
- head also has [blank_start]SVE[blank_end] as well as [blank_start]AA[blank_end], A[blank_start]E[blank_end], [blank_start]SA[blank_end], S[blank_start]E[blank_end]- Adorsal
