Question | Answer |
Function of glands. | Secrete hormones. |
Hormones. | Chemical messenger. |
Life process involved with the endocrine system. | Regulation. |
Regulation. | Control and coordination. |
Receptor molecules must have a specific __________ that matches the _____________ of the hormone. | Shape. |
Name of the cell that has the correct receptor shape for the hormone. | Target cell. |
Name of the cell that does not have the correct receptor shape for the hormone. | Non-Target cell. |
A type of feedback mechanism or loop that tends to oppose an initial change and thus maintains the stability of the quantities involved. | Negative feedback. |
Why is negative feedback important for an organism? | It helps it maintain homeostasis. |
What does a graph showing negative feedback look like? | A series of lines that go up and down constantly. |
Describe how negative feedback affects the endocrine system. | The secretion of a hormone is controlled by the concentration of another substance in the blood, often another hormone. |
Pituitary gland. | Controls the activity of other glands and hormones, otherwise known as the "master gland", located in the brain. |
Four hormones secreted by the pituitary gland. | TSH (thyroid hormone), ACTH, GH (growth hormone), and FSH (egg cells). |
Hypothalamus. | Controls the release of hormones by the pituitary and serves as a major link between the nervous system and the endocrine system, helps with temperature regulation. |
Thyroid gland. | Located in the neck, secretes thyroxine, regulates rate of metabolism. |
Parathyroid gland. | Located on the side of the thyroid gland, secretes parathormone, regulates calcium and phosphate metabolism. |
Adrenal gland. | Located on the top of the kidneys, secretes adrenaline, epinephrine, and cortisone, activated during emergencies and stressful situations. |
Pancreas. | Otherwise known as Islets of Langerhans, secretes glucagon (increases carbs) and insulin (decreases carbs), affects glucose levels, can lead to diabetes. |
Gonads. | Sex glands. |
Ovaries. | Produce egg cells, secrete estrogen and progesterone. |
