Serotonin (4)
Mood, appetite, social behavior, and memory
Hypocritin (aka orexin)

Grehlin
“hunger hormone” increase in appetite
Estradiol
Produced from the follicle in the ovary
Prolactin
Released by the anterior pituitary. Related to sexual gratification and is associated with relieving sexual arousal after an orgasm.
Luteinizing Hormone
Released by the anterior pituitary. An increase in LH triggers ovulation.
Follicle-stimulating hormone
