Straight
_____ arteries supply blood to the stratum functionalis
Spiral
_____ follicle: completely formed at 6 months of life, surrounded by layer of pregranulosa cells
Primordial
_____ follicle: contains primary oocyte surrounded by zona pellucida surrounded by a single layer of cuboidal granulosa cells
Primary
_____ follicle: contains several layers of cuboidal granulosa cells with adjacent stroma differentiating into theca cells
Secondary
_____ follicle: corona radiata enveloped in antral fluid attached to remaining granulosa cells by a stalk
Graafian
_____ follicle: differentiation of the theca interna and theca externa
Tertiary/antral
_____ follicle: Fluid-filled space develops in the granulosa cell layer
Tertiary/antral
______ augments FSH activities of granulosa cells and suppresses androgen production by theca cells
Activin
______ enhances LH stimulation of androgen synthesis to provide more substrate for estrogen synthesis
Inhibin
_____: deepest layer of endometrium, adjacent to myometrium
