Flashcards in Pituitary Disorders Deck (24):
1

the pituitary gland consists of 2 parts, the anterior and posterior. what are other names related to these parts?

anterior = adenohypophysis
posterior = neurohypophysis

2

the anterior secretes which six hormones

TSH, ACTH, GH, prolaction, LH, FSH

3

what 2 hormones are released by the posterior?

ADH and oxytocin -- they are stored in the hypothalamus and then released by posterior pituitary

4

______ and _________ activate release of substances by posterior pituitary gland when they are stimulated by nerve impulses from the hypothalamus

ACh and NE

5

what is hyperpituitarism?

oversecretion of one or more of the hormones secreted y the pituitary

6

what is oversecretion of GH?

acromegaly or gigantism

7

what is oversecretion by the pituitary gland caused by?

hormone secreting pituitary tumor, Cushing's Disease (over secretion of ACTH), amenorrhea and hyperthyroidism

8

Tumors of the pituitary have 3 systemic effects:

1. excessive or abnormal growth patterns
2. hyperprolactinemia (amenorrhea, galactorrhea, gynecomastia)
3. overstimulation of one or more of the target glands resulting in release of excessive ATCH, TSH, or FSH/LH

9

s/s of low TSH = hypothyroid

weakness, muscle aches, stiffness

10

s/s of high TSH = hyperthyroid

nervousness, fatigue, weakness, tachycardia, trmeor

11

s/s of acromegaly/gigantism

enlargement of hands, feet, face, jaw
amenorrhea
parasthesia of hands
sweating, HA, impotence
DM, HTN
joint pain, muscle weakness, and reduce exercise tolerance

12

what is the medical manage of hyperpituitarism - acromegaly?

resection of tumor, suppression of GH with somatostatin, and external radiation

13

what are PT implications for acromegaly

progress cautiously; focus on: energy conservation, joint proteciton and fall preventio

14

what are the s/s of hypopituitarism - GH

regression of sexual characteristics (decreased LH/FSH)
short stature/dwarfism

15

what causes hypopituitarism - ACTH

adrenocortical insufficiency = diminished secretion of adrenocortical hormones by the adrenal cortex

16

what are s/s of hypopituitarism -LH and FSH

decreased production of sex hormones (estrogen, progesterone, and testosterone)

17

what is the name for hyperpituitarism - ACTH

Cushing's Disease

18

what are the s/s of cushing's disease?

moon face, osteoporosis, buffalo hump, wasted limbs, abdominal obesity, cardiac hypertrophy and poor wound healing

19

what are the s/s of hypopituitarism - ACTH

glucocorticoid defieciency = hypoglycemia, nausea, abdominal pain, and orthostatic hypotension

20

what is the name for hyperpituitarism - ADH

SIADH = syndrome of inappropriate antidiuretic hormone

21

s/s of SIADH

excessive water retention and water intoxication; hyponatremia (sodium depletion)

22

what are s/s of hyponatremia?

HA, confusion, seziures, decreased consciousness, restlessness, muscle spasms, weakness, N/V

23

what is the name for hypopituitarism - ADH

Diabetes Insipidus

24

what are s/s of diabetes insipidus

polyuria, thirst, dehydration, weight loss, ataxiA = excessive fluid secretion
