Students have asked these similar questions
In the anterior pituitary region, do you see multiple cell types in each follicle or does each follicle contain a
single cell type? How can you tell each cell type apart from one another? Hint: think about the names and
staining.
Choose between LH, inhibin, FHS and testosterone
Describe the general functions of FSH, LH, estrogen, and progesterone in females.
