Endocrine Glands
| Term | Definition |
|---|---|
| Thyroid Hormones (T3 and T4) | Gland: Thyroid Gland Cells Producing: Follicular Cells Stimulus: TSH from anterior pituitary gland Target Organ: Most cells in the body Effect: Increase Basal Metabolic Rate |
| Calcitonin | Gland: Thyroid Gland Cells Producing: Parafollicular cells Stimulus: High blood calcium levels Effect: Lower blood calcium levels |
| Mineralcorticoids (aldosterone) | Gland: Adrenal cortex of the adrenal gland Zone: Zona glomerulosa Stimulus: Low blood pressure and low blood volume Target organ: Kidney Effect: Raise blood pressure and blood volume |
| Glucocorticoids (cortisol) | Gland: Adrenal cortex of the adrenal gland Zone: X Zona Fasciculata Stimulus: ACTH from the anterior pituitary gland Target: Most cells in the body Effect: Long term stress response; suppresses immune system |
| Norepinephrine epinephrine | Gland: Adrenal medulla of the adrenal gland Stimulus: Sympathetic nervous system Target: Most cells in the body Effects: Fight or flight response |
| Insulin | Gland: Beta cells in the islet of lagerhans in the pancreas Stimulus: High blood glucose levels Target: Most cells in the body Effect: Decrease blood glucose levels by allowing cells to absorb glucose |
| Glucagon | Gland: Alpha cells in the islet of lagerhans in the pancreas Stimulus: Low blood glucose levels Target: Liver and adipose cells Effect: Increases blood glucose levels |
| Adrenocorticotrophic hormone | Gland: Anterior pituitary gland Target: Adrenal cortex Effect: Increases release of glucocorticoids and mineral corticoids |
| Follicle-Stimulating hormone | Gland: Anterior pituitary gland Target: Gonads Effect: Stimulates the development of gametes |
| Luteinizing hormone | Gland: Anterior pituitary gland Target: Gonads Effect: Females- Stimulates ovulation; Males: Stimulates production of testosterone |
