Auxins

Growth hormone in plants that is responsible for cell elongation, phototropism, cell division, and fruit development

Gibberellins

Growth promoting hormones that promote elongation, found in leaves, roots, embryos, seeds, and fruits

Cytokinins

Promote cell division, prevent senescence (aging) of leaves, initiate leaf growth, and works with auxins to differentiate plant tissues

Abscisuc Acid

Plant stress hormone that closes stomata and maintains dormancy

Ethylene

Plant hormone responsible for the ripening of fruit, abscission (leaf drop) and stimulating cellulose

Gonadotropin-releasing hormone (GnRH)

Hormone from the hypothalamus that causes the anterior pituitary to release FSH and LH

Follicle-stimulating hormone (FSH)

Stimulates sperm production in males. In females, it regulates the menstrual cycle. Encourages the follicles on the ovary to grow and prepare the eggs for ovulation.

Testosterone

male sex hormone that stimulates the production of sperm and secondary sex characteristics

Estrogen

Maintains female secondary sex characteristics

Progesterone

Responsible for breast development and thickens the uterine lining for the eggs to implant within. Made by the corpus luteum.

Human chorionic gonadotropin (hCG)

hCG maintains corpus luteum, is what pregnancy tests look for

Gonorrhea (Neisseria Gonorrhoeae)

Bacterial STD that causes painful urinations and greenish yellow discharge in males. In females there are usually no symptoms and called to PID (pelvic inflammatory disease)

Syphilis

Bacterial infection. Starts as a sore that is painless it can eventually become active again after long periods of inactivity, and can cause damage to the heart brain or other organs.
