Assessment of the Endocrine System Chpt 37

QuestionAnswer
Hormone
Occuring during the day Diurnal
Caused by treatment; med-related side effects Iatrogenic
Milk secretion not associated with childbirth or nursing Galactorrhea
Having a dopamine-like effect Dopaminergic
Decreased secretion of sex hormones by the ovaries or testes Hypogonadism
Urinary sodium excretion Natriuresis
Excesive water loss from the body Polyuria
Excessive or abnormal thirst Polydipsia
Forward projection or displacement especially of the eyeball Proptosis
Abnormal protrusion of the eyeball Exophthalmos
Severe hypothyroidism characterized by firm inelastic edema, dry skin & hair, loss of mental & physical vigor Myxedema
Characterized by normal thyroid function Euthyroid
TSH stimulates the thyroid gland to secrete? Thyroxine T4 & Triiodothyronine T3
Physiologic levels of hormones are determined by: amount of hormone produced, intact transport system, adequate receptors, feedback systems, metabolic degradation of hormone
Hormone release is influenced by: Negative feedback systems, intrinsic rhythmicity, the nervous system, excretion, & metabolism.
Time period for measuring TSH levels 6-8 weeks
Cortisol levels are highest at what time? Highest in morning
Growth Hormone levels peak at what time? Highest at night
The kidneys & liver are primarily responsible for: Hormonal inactivation & excretion
A benign tumor of a glandular structure or origin; produces hormones-mostly Cortisol Adenoma
Hormones may be transported by the circulatory system either in a: Free state or bound to plasma proteins.
Synthroid should be given at what time of day? Morning
The hypothalamus controls the: Posterior & Anterior pituitary glands
The posterior pituitary gland stores & releases 2 hormones: Antidiuretic hormone(ADH)Vasopressin & Oxytocin
Iodine is necessary for the synthesis of what hormone? Thyroid hormone
The follicular cell is the function unit of the thyroid is responsible for production of T4 & T3
Serum calcium levels influence the release of Calcitionin; maintains normal levels
Parathyroid gland produces PTH, which regulates Calcium levels in the blood; by bones & kidneys
Calcitonin & vitamin D are also involved in: Calcuim regulation; can effect heart
Adrenal Gland produces Glucocorticoids & Mineralocorticoids in response to stress; critical for life.
Adrenal Medulla produces Epinephrine & Norephinephrine
The pancreas secretes Glucagon, Insulin, Somatostatin, & Pancreatic Polypeptide
Actions of Somatostatin: Inhibits gastric motility & emptying, gallbladder contraction; intestinal absorption of fats, amino acids, glucose, & other nutrients
Somatostatin helps maintain glucose homeostasis in nondiabetic people
Synthetic somatostatin is used to treat Acromegaly
Hormonal changes assoc. with aging: Changes in hormone clearance, reduction in cellular responsiveness to certain hormones, changes in nutritional satus, physical activity, & body composition.
Hormones that affect energy levels T4, T3, Testosterone, & GH
Addison's disease destructive dz marked by deficient adrenocortical secretion & characterized by extreme weakness, weightloss, low BP, GI disturbances, & brownish pigmentation of the skin & mucous membranes
Physical Exam should focus on pigmentation, skin texture, growth patterns, & visual fields
Hypothalamus releases ADH in response to: Changes in osmolality & body water volume
secreted by anterior lobe of the pituitary gland; stimulates the contraction of uterine muscle & the secretion of milk Oxytocin
The difference between T4 & T3: A change in the molecule
Bound to Iodine T3- Triidothyronine
Parathyroid works to increase what level Calcuim
Access fluid intake Polydipsia
