T-6 spinal ganglion, T-7 ventral primary ramus, allantois, dorsal mesentery, edge of cranial limb of midgut loop, ependymal layer, extravasated blood cells, ganglion cells, genital tubercle, intercostal nerve (T-8), mammary ridge, mantle layer, marginal layer, mesenchymal condensation (mesoderm), postcardinal vein, primitive cecum, primitive filum terminale, ramus communicans, right and left umbilical arteries, sclerotome, sympathetic trunk, tail bud, urethral plate

A section through the primitive cecum and genital tubercle.

Observe:
1. The three layers of the spinal cord.
2. The caudal edge of the cranial limb of the midgut loop to the right of the midline.
3. The urethral plate on the ventral surface of the genital tubercle.
4. The continuity of the urethral plate with the cloacal membrane in Section 30.
