ch. 7 Flashcards
endocrine sys functions
maintain homeostasis. Adjust nutrient levels Respond to the environment Direct growth and development Endocrine system organs function by: Sending signals to other organs. Receiving signals from other organs. Changing their behavior based on the signals. Signals are sent from one organ to another via the bloodstream.
hypothalamus
structure in your brain that makes and releases many hormones
sends hormones into the blood that travel directly to the anterior pituitary gland
Hormones from the
anterior pituitary gland
stimulate other
endocrine glands.
Aden/o
gland
Adren/o, adrenal/o
adrenal gland located on top of kidney like party hat
Cortic/o
outre surface referring to adrenal cortex
Gonad/o
sex organs, testes and ovaries
Pancreat/o
pancreas
Pituitar/o, hypophsy/o
pituitary gland
Thym/o
thymus
Thyr/o, thyroid/o
thyroid
Gluc/o, glucos/o,
glyc/o
sugar
Crin/o
secretion, to secrete
pituitary gland
secretes hormones
into the blood that act on other organs
Adrenocorticotropic hormone (ACTH)
Stimulates the outer part of the adrenal gland, pit gland
Thyroid-stimulating hormone (TSH)
Thyroid secretes T3, T4, and
calcitonin, pit gland
Luteinizing hormone (LH) and folliclestimulating hormone (FSH)
Stimulate the gonads, pit gland
Thyroid gland
T3 and T4
Hyperthyroidism
Hypothyroidism
Calcitonin

Pancreas
Endocrine function is to secrete hormones Insulin – decreases blood sugar Glucagon – increases blood sugar
Adrenal gland
Adrenal gland Medulla Epinephrine (adrenaline) Cortex Corticosteroids • Mineralocorticoids: mineral balance • Glucocorticoids- sugar balance • Testosterone and estrogen
Hormone levels are
detected by
measuring blood
concentration levels
of nutrients.
Common
measurements:
- Hyperglycemia: high blood sugar
- Hypoglycemia: low blood sugar
- Euglycemia: good blood sugar
Can also measure
endocrine function
by
urinalysis
•Glucosuria: sugar in urine- sign of diabetes
•Ketonuria: ketones in the urine- faulty carb digestion
Hormon/o
hormone
Ket/o
ketone bodies
-tropin
stimulating hormone, stiumaulates another hormone
-emia
blood condition
-uria
urin cond
Adenalgia
pain in a gland
Adrenal virilism
dev of male secondary sex characterists from an overactive adrenal gland– like facial hair or low voice
Adrenarche
beginning of adrenal secretion, happens at puberty
Hirsutism
excessive growth of body or facial hair in women
Amenorrhea
absence of menstrual cycle
Gynecomastia
dev of breast tissue in males
Hypergonadism
condition of excessive secretion of the sex glands
Hypogonadism
undersecretion of the sex glands- steroid use symptom
Menarche
beginning of menstration– first cycle
Thelarche
beginning of breast dev
Hypoglycemic
low blood sugar
Pancreatalgia
pain in the pancreas
Polydipsia
excessive thirst
Polyphagia
excessive hunger
Polyuria
excessive urination
Acromegaly
abnormal enlargement of extremeties
Galactorrhea
discharge of milk
Pituitary dwarfism
absnormally short height caused by under secretion of growth hormone from pit gland
Pituitary gigantism
absnormally tall height caused by over secretion of growth hormone from pit gland
Exophthalmos
bulging eyes
Thyrocele, goiter
swollen thyroid gland
Thyromegaly
enlarged thryoid
Thyroptosis
drooping thyroid
evaluating endocrine abnormalities
Blood tests (-emia)
Urine analysis (-uria)
Chloremia
increased chloride in the blood
Hypercalcemia
excessive calcium in blood
Hyperkalemia
excessive potassium in blood
Hypernatremia
excessive sodium in blood
