Term
| What is the hypothalamus' role? |
|
Definition
the link between the nervous system and the endocrine system
Major role is control of the pituitary |
|
|
Term
| What is a negative feedback system? |
|
Definition
| the diminution or counteraction of an effect by its own influence on the process giving rise to it, as when a high level of a particular hormone in the blood may inhibit further secretion of that hormone, or where the result of a certain action may inhibit further performance of that action. |

Definition
Follicle-stimulating hormone (FSH)
Luteinizing hormone (LH)
Prolactin
Adrenocorticotropic hormone (ACTH)
Thyroid-stimulating hormone (TSH)
Growth hormone (somatotropin) |
|
|
Term
| What does the posterior pituitary gland release? |
|
Definition
|
|
Term
| What does the thyroid release? |
|
Definition
|
|
Term
| What does the parathyroid release? |
|
Definition
|
|
Term
| What does the adrenal medulla release? |
|
Definition
| catecholamines (epi/norepi) |
|
|
Term
| What does the adrenal cortex release? |
|
Definition
| steroid hormones (glucocorticords, mineralocorticoids, androgens) |
|
|
Term
| What do the pancreatic islets release? |
|
Definition

|
|
Term
| What controls the pituitary gland? |
|
Definition
|
|
Term
What nursing diagnosis is most likely to apply to a patient who has a dysfunction of the posterior lobe of the pituitary gland?
Deficient fluid volume
Risk for infection
Ineffective tissue perfusion
Risk for imbalanced body temperature |
|
Definition
|
|
Term
|
Definition
| Controls cellular metabolic activity |
|
|
Term
|
Definition
| Reduces the plasma level of calcium by increasing its deposition in bone |
|
|
Term
| What does parathormone do? |
|
Definition
| Causes osteoclast growth and bone resorption |
|
|
Term
| What do the beta cells in the islets of the pancreas secrete? |
|
Definition
|
|
Term
| What do the alpha cells in the islets of the pancreas secrete? |
|
Definition
|
|
Term
Is the following statement true or false?
Removal of the parathyroid glands would create a risk of low serum calcium levels. |
|
Definition
True
Rationale: In the absence of parathormone, there is decreased intestinal absorption of calcium and decreased resorption of calcium. This results in hypocalcemia. |
|
|
Term
An individual has experienced recent changes in voice, hair, and sex drive. The nurse should suspect dysfunction of what endocrine gland?
Thyroid
Posterior pituitary
Parathyroid
Adrenal glands |
|
Definition
D. Adrenal glands
Rationale: Adrenal dysfunction often causes changes in voice, hair, and sexual drive (related to androgens). These changes are not typically related to the thyroid gland, parathyroid glands, or pituitary gland. |
|
|
Term

|
Definition
|
|
Term
| What is the patho of hormone release of the adrenal glands? |
|
Definition
| (hypothalamus →Corticotropin Release Hormone which stimulates→ pituitary to release AdrenoCorticoidTropic Hormone → stimulates the adrenal hormones including glucocorticoids, mineralocorticoids, and androgens) |
|
