Thecal cells
Give this one a try later!
Found in primary/secondary follicles in ovaries:
respond to LH to produce androgens like androstienedione
Wolfian Duct
Give this one a try later!
Converted by testosterone into seminal vesicle, vas deferens and
epididymus
DHT controls development of prostrate
,Melatonin
Give this one a try later!
Darkness hormone, secreted at night, transmits information of light-dark
cycles, governs biological clock.
Immune modulation
Anti-oxidant
Second/third cell lineage in embryo development
Give this one a try later!
-Epiblast: what becomes the actual organism
-Primary endoderm
Exchange of gasses in placenta (which vessel carries oxygenated vs non oxygenated)
Give this one a try later!
Umbilical artery brings deoxygenated blood to chorionic villi.
-Chorionic villi are bathed in maternal oxygenated blood.
-Oxygen diffuses into the chorionic villi blood, CO2 diffuses out
-Oxygenated embryonic blood goes back to embryo via umbilical veins.
Cortisol
Give this one a try later!
, Steroid Hormone, overall purpose is to prevent hypoglycermia -->
catabolic. 1. Promotes gluconeogenesis in the liver. 2. Causes breakdown of
skeletal muscle. 3. Enhances lipolysis. 4. Supresses the immune system. -has
permissive effect on glucagon. 5. Causes negative calcium balance (less
ingested, more secreted, breaks down bones). 6. Influences brain function
Male development gene cascade

SRY |----> SOX9 <---> AMH
Epiphyseal Tissue
Give this one a try later!
Bone model precurser (made of cartiledge) once ossified = bones. Bones
only fully develop in adults when epiphyseal plates fuse
Placental hormone: estrogen
Give this one a try later!
-stimulates formation of breast ducts
-stimulates growth/development of the uterine lining (vascularization,
oxytocin receptors, etc)
