A section through the T-8 neural crest, L-3 dermatome and caudal part of the coelom.
Observe:
1. Dermatomes in cross section (L-3) and oblique section (T-9).
2. The near junction of the mesonephric ducts.
3. The mesonephric vesicles and duct between the caudal part of the coelom and the dorsal aorta.
4. The mesothelial lining of the coelom.
