vocab related to pituitary gland and stress response
| Term | Definition |
|---|---|
| Glucocorticoid | makes glucose available(increased blood sugar), messes with formation of memory |
| Glucocorticoid Outcomes(long term stress) | 1. Proteins and fats get broken down and converted to glucose, leading to inc. BGL 2. Immune system may be suppressed |
| Mineralocorticoid Outcomes(long term stress) | 1. Retention of NA+ and water by kidneys 2. Inc. BP and Blood volume |
| Epinephrine and Norepinephrine Outcomes(short term stress) | Inc BP, BGL, Metabolism, Breathing, Alertness, Kidney function |
| Portal System | capillary bed leading into another capillary bed |
| Stress leads to... | heart attacks, strokes, diabetes, high cholesterol, suicide, depression |
| CC Endocrine and Neurosecretory Cell | endocrine is longer lasting, neurosecretory is faster |
| Chromaffin, what is it? What does it release? | neurosecretory, releases hormones into blood |
| Hormones from Anterior | Growth Hormone(GH), Prolactin(PRL), Thyroid Stimulating Hormone(TSH), Adrenocorticotropic Hormone(ACTH) |
| Thyroid Stimulating Hormone | stimulates thyroid hormone release |
| Growth Hormone | promotes growth of body tissue, protein |
| Prolactin | promotes milk production |
| Adrenocorticotropic Hormone | stimulates hormone release by adrenal cortex, glucocorticoids |
| Hormones from Hypothalamus(posterior) | Releasing and inhibiting hormones, ADH |
| Releasing and Inhibiting Hormones | regulate hormone release from pituitary gland, produce oxytocin, uterine contraction, and milk secretion |
| Antidiuretic Hormone | water reabsorption from kidney, vasocontraction to increase blood pressure |
| CC Adrenal Medulla and Adrenal Cortex | Medulla is faster and receives info from neurosecretory, Cortex is slower and receives info from blood |
