1The process by which the germ layers are formed is known as [blank_start]gastrulation[blank_end]
- Agastrulation
2Name these layers that are formed in the very early stages of embryonic development
- AEpiblast
- BHypoblast
3Name the following structures
- APrimitive node
- BPrimitive streak
4Mesoderm cells migrate through which structure to form the middle germ layer?
- APrimitive Streak
- BHypoblast
- CAmniotic Yolk cells
- DWall of amniotic cavity
5After the formation of the mesoderm, it splits into three sections. Arrange them from medial to lateral:
[blank_start]Paraxial mesoderm[blank_end]
[blank_start]Intermediate mesoderm[blank_end]
[blank_start]Lateral plate of the mesoderm[blank_end]- AParaxial mesoderm
- BIntermediate mesoderm
- CLateral plate of the mesoderm
6The urogenital system develops from the [blank_start]intermediate mesoderm[blank_end].
- Aintermediate mesoderm
- Blateral plate of the mesoderm
- Cparaxial mesoderm
7Germ cells that are still to reach the gonads are known as [blank_start]Primordial[blank_end] Germ Cells (PGCs)
- APrimordial
8During weeks 4-6 of development, primordial germ cells migrate from the [blank_start]yolk sac[blank_end] to the [blank_start]intermediate mesoderm[blank_end] thus forming the [blank_start]primitive sex cords[blank_end]
- Aprimitive sex cords
- Bmesonephric ducts
- Cintermediate mesoderm
- Dparaxial mesoderm
- Eyolk sac
9In terms of genital duct development:
The Wolffian ducts are also known as [blank_start]mesonephric ducts[blank_end]

[blank_start]Leydig[blank_end] cells
[blank_start]Sertoli[blank_end] cells- ALeydig
- BSertoli
12Leydig Cells produce [blank_start]Testosterone[blank_end]
Sertoli Cells produce [blank_start]Anti-Mullerian Hormone[blank_end]- AAnti-Mullerian Hormone
- BTestosterone

- AParamesonephric
- BMesonephric
14The structure of the developing testes that connects the mesonephric duct to the sex cords is called the [blank_start]Rete[blank_end] Testis
- ARete
15Which hormone induces formation of epididymis, vas deferens, seminal vesicles?
