VTPP 434 EXAM 3 QUESTIONS AND ANSWERS 100% CORRECT
AND GRADED A+
FSH
Answers:follicle stimulating hormone- regulates gametogenesis
LH
Answers:luteinizing hormone - controls sex hormone secretion
inhibin
Answers:inhibits FSH secretion in males and females. secreted by sertoli cells in
males
kisspeptin
Answers:peptide hormone that controls the release of GnRH from hypothalamus
primary follicle
Answers:primary oocyte surrounded by single layer of granulosa cells. Both are
growing
secondary follicle
Answers:primary oocyte is larger and more granulosa cells surround. Thecal cells
start forming to convert cholesterol to estrogen
tertiary follicle
Answers:fluid filled cavity forms (antrum) until the follicle ruptures and releases

corpus luteum
, Answers:remaining follicle after oocyte is released. produces progesterone for 12-
14 days. regresses if egg is not fertilized or supports fertilized zygote until placenta
forms
glial cells (4 types)
Answers:astrocytes, oligodendrocytes, microglia, ependymal cells
Astrocytes
Answers:- hold neurons in proper alignment
-establish blood brain barrier
- scaffolding
- recycle glutamate and GABA
- Take up K+
- take up Ca++
- Affect neural excitability
Oligodendrocytes
Answers:for myelin sheaths around axons
microglia
Answers:part of immune system but are like bull in china shop -- release GF to
help neurons and glial cells grow
Ependymal cells
Answers:make the cerebral spinal fluid and decides what can go from cerebral
spinal fluid and brain interstitial fluid
