| Question | Answer |
|---|---|
| Major effects are directed to growth of skeletal muscles and long bones | Growth Hormone |
| Stimulates and maintains milk production following childbirth. Function in males in unknown | Prolactin |
| Regulates endocrine activity of the adrenal cortex | adrenocorticotropic hormone |
| Influences growth and activity of the adrenal cortex | thyroid stimulating hormone |
| Stimulates follicle development in ovaries. Stimulates sperm development in testes | Follicle- Stimulating Hormone |
| Triggers ovulation. Stimulates testosterone production in males | Luteinizing hormone |
| Can inhibit urine production | Antidiuretic hormone |
| Stimulates contractions of the uterus during labor. Causes milk ejection | oxytocin |
| controls the speed of metabolism | Thyroid hormone |
| decreases blood calcium levels by causing its deposition on bone | Calcitonin |
| Stimulate osteoclasts remove calcium from bone. Raise calcium levels in the blood | parathyroid hormone |
| regulated mineral content in blood water and electrolyte balance | mineralocorticoids |
| Promotes normal cell metabolism. Help resist long term stressors | glucocorticoids |
| is made up of androgens (male) and some estrogen (female) | Sex hormones |
| these hormones prepare the body to deal with short term stress | epinephrine/norepinephrine |
| causes glucose absorption and a decrease in blood glucose | glucagon |
| helps establish the body's wake and sleep cycles | melatonin |
| matures some types of white blood cells. Important in developing the immune system. | thymosin |
| matures female reproductive organs. helps prepare the uterus to receive a fertilized egg. Helps maintain pregnancy. Prepares the breasts to produce milk | estrogen |
| acts with estrogen to bring about the menstrual cycle. Helps in the implantation and maturation of male reproductive system. Required for sperm cell production. | testosterone |
| What is the endocrine system responsible for? | Chemical messenger system->produces hormones |
| What is not one of the three possible makeups of hormones? | Lipids, amino acids, or cholesterols. |
| What exactly do hormones do? | They are chemical messengers released by glands in to the bloodstream. They create reactions in target cells. |
| What is the pituitary gland attached to? | The hypothalamus |
| Where is the thyroid located? | Base of the front of your neck(throat/neck). |
| Where is the parathyroid gland located? | Posterior surface of the thyroid gland. |
| What are the two lobes of the adrenal glands? | cortex and medulla |
| Which of the following is Not an endocrine disruptor? | Endocrine disruptors: BPA, phytoestrogens, trielosan |
| Which of the following is not an endocrine gland? | Refer back to diagram-exocrine gland: exocrine gland ex:sweat-outside of the body |
| What is is about a cell that identifies it as a target cell for a hormone? | receptors |
| In general the response of target cells to endocrine stimulation is _________than their response to nervous stimulation. | slower-effects last longer |
| In your own words explain the cascade effect in the endocrine system. | The cascade effect in the endocrine system is a chain-reaction mechanism. The hypothalamus releases TRH. TRH stimulates the pituitary gland to release TSH. |
| Blood glucose chart right side: | eat candy bar-->increase in blood glucose-->pancreas produces insulin--> insulin binds to our cells to take up glucose-->blood glucose levels decrease |
| Blood glucose chart left side: | have not eaten-->blood glucose levels decrease-->pancreas sends glucagon to liver-->liver converts glycogen to glucose-->glucose is released into bloodstream-->blood glucose levels increase |
| How does the endocrine system and another system work together to create homeostasis.pt 1 | The endocrine and the NS and muscular system work together to maintain homeostasis. The hypothalamus is the thermostat. When you get hot your nervous system senses the temperature and and sends signals to sweat glands to cause vasodilation>releases heat. |
| How does the endocrine system and another system work together to create homeostasis.pt 2 | When you get cold your nervous system sends signals to the muscular system to shiver. This causes vasoconstriction to hold onto heat. |
