What are the special cells in the pancreas called
Islets of Langerhans
What are the hormones produced my islets of langerhans do
Control blood sugar levels
What are the 2 hormones released by the islets of langerhans
Insulin
Glucagon
Where is insulin secreted from
What does insulin do
What does insulin promote
Beta gells
Lowers blood glucose levels
Promotes the formation of glycogen in the liver
Where is glucagon secreted from
What does glucagon dk
Alpha cells
Raises blood glucose levels by changing glycogen to glucose
What type of hormones do the ovaries and testes produce
Reproductive hormones
What does the thymus gland do
Mature T lymphocytes
Where is the pineal gland
What does it produce
Attached to the base of the brain
Makes melatonin
What are the 7 reproductive hormones
Gonadotropin Releasing Hormone (GnRH)
Follicle Stimulating Hormone (FSH)
Luteinizing Hormone (LH)
Estrogen
Progestrone
Testosterone
Human Chorionic Gonadotropin (HCG)
Where is gonadotropin releasing hormone produced
What does it cause in both male and females
Produced in the hypothalamus
Causes FSH and LH to be released from the anterior pituitary gland in males and females
Where is follicle stimulating hormone produced
What does it cause in males (2)
What does it cause in females (4)
Produced by the anterior pituitary gland
In males - cause the sex organs to develop and sex cells to be produced
In females - causes the sex organs to develop and sex cells to be produced, stimulates follicle to mature, stimulates the follicle to produce estrogen
Where is luteinizing hormone produced
What does it cause in males
What does it cause in females (3)
Produced in the anterior pituitary gland
In males - cause testosterone production by the interstitial cells
In females - causes ovulation, helps with estrogen production, causes the mature follicle to develop into the corpus luteum and causes it to produce progessterone
Where is estrogen produced
What does it cause (2)
Produced in the ovary (follicle)
Causes development of the female reproductive system
Causes the development of the secondary sex characteristics
Where is progesterone produced
What does it cause the uterus to do
Produced in the ovary (corpus luteum
Causes the wall of the uterus to thicken
Where is testosterone produced
What does it promote
What does it cause (2)
Produced in the testes (interstitial cells)
Promotes sperm production
Causes development of the male reproductive system
Causes the development of the secondary sex characteristics
Where is human chorionic gonadotropin produced
What does it help with
What does it allow the corpus luteum to do
Produced by the placenta
Helps to maintain the corpus luteum and prevent menstruation
Allows the corpus luteum to continue to produce progesterone
What does progesterone help maintain
Maintains the endometrium so it can support the fetus
