SB7 Flashcards
Name the 6 organs/glands that produce hormones
Adrenal gland- Adrenaline
Ovaries- Progesterone and Estrogen
Testes- Testosterone
Thyroid gland- Thyroxine
Pituitary gland- Growth hormone
Pancreas- Insulin
Describe the functions of each of the 6 hormones.
Adrenaline (produced by the adrenal gland) is used during the fight or flight response.
The growth hormone (produced by the pituitary gland) is used in order to regulate growth, metabolism, and reproduction
Thyroxine (produced by the thyroid gland) is used in order to regulate metabolism and helps control the bodies energy production
Insulin (produced by the pancreas) helps to control the blood sugar levels and regulates the amount of glucose within the body.
Estrogen (produced by the ovaries) causes growth and repair of the lining of the uterus wall. Inhibits FSH. When oestrogen rises to a high enough level, it causes a surge in LH from the pituitary gland which causes ovulation where an egg is released from the follicle (day 14 of the cycle)
Progesterone (produced by the ovaries) maintains the uterus lining (the thickness of the uterus wall). If the egg has not been fertilized the corpus luteum dies and progesterone level drops. This causes menstruation where the uterus lining breaks down, this is also known as a period.
Testosterone (produced by the testes) is the male sex hormone that that cause the development of secondary sexual characteristics in a male. Stimulates the production of sperm in males. In increase hair in certain parts of body, muscle growth, deepness of voice, sperm production and penis and testes develops.
What are the key glands that are a part of the endocrine system?
Your endocrine system consists of the tissues (mainly glands) that create and release hormones.
Describe how negative feedback can control the amount of a hormone in the blood.
When the level of a hormone in the bloodstream is too high, it triggers the release of a different hormone that decreases its production.
What inhibits FSH and LH from being produced
Progesterone inhibits FSH and LH
What hormone inhibits FSH
Oestrogen inhibits FSH
What happens to the concentration of Oestrogen at ovulation.
It drops after ovulation.
