Oocytes inactive until puberty
FSH causes them to mature
Meiosis completed only if sperm penetrates
Creates 2 polar bodies - cells only females have
What are the stages of the menstrual cycle?
Menses - endometrium is sloughed off
Proliferative stage - regeneration of functional layer
Secretory stage - endometrium increases in size and prepares for implantation
What are the mammary glands?
Modified sweat glands that produce milk
What are the parts of the mammary gland?
