What are the clusters of cells in the pancreas called?
|
pancreatic islets (islets of langerhans)
|
|
What's the conversion of glycogen to glucose?
|
glycogenolysis
|
|
What is glucose formation from amino acids, lacate, etc?
|
gluconeogenesis
|
|
Low blood glucose?
|
hypoglycemic
|
|
High blood glucose?
|
hyperglycemic
|
|
What increases blood glucose level by "breakdown?"
|
Glucagon
|
|
What decreases blood glucose?
|
Insulin
|
|
What's the conversion of glucose to glycogen?
|
glycogenesis
|
|
What's the conversion of glucose or amino acids to fatty acids?
|
lipogenesis
|
|
sentarse
|
to sit down
|
|
insulin secretion may be normal or even increased, but skeletal muscle, adipose tissue, liver, are less sensitive than normal. (obesity)
|
Type II diabetes
|
|
Elevated blood glucose levels exceed the reabsorption capacity for glucose in the kidney leading to excretion of glucose in urine
|
glucosuria
|
|
Glucose in urine exerts an osmotic effect preventing reabsorption of water and leading to increased urine production
|
Polyuria
|
|
Excessive thirst
|
polydipsia
|
|
increased breakdown of fatty acids associated with insulin deficiency, and their use by liver results in excessive production of __________
|
ketone bodies (keto acids)
|
|
The resulting acidosis (__________) leads to electrolyte imbalance which affects the brain causing coma and death if untreated
|
Diabetic ketoacidosis
|
|
Chronic secondary complications of diabetes include effects on small blood vessels in circulation, which can cause_________
|
diabetic neuropathy and blindness, deteriation of glomerular filtration in kidneys, amputation of leg or foot
|
|
Consists of glandular epithelial tissue and is connected with the hypothalamus by blood vessels
|
Anterior Pituitary
|
|
Contains axon terminals whose cell bodies are located in the hypothalamus
|
Posterior Pituitary
|
|
Causes cells to grow and multiply by facilitating entry of amino acids into cells and conversion into proteins
|
Human growth hormone (hgH) -anterior pituitary
|
|
stimulates secretion of thyroid hormone and growth of the thyroid gland
|
Thyroid-stimulating hormone (TSH; Thyrotropin) A Pit
|
|
stimulates cortisol secretion by the adrenal cortex
|
Adrenocorticotropic Hormone (ACTH) A pit
|
|
has different functions in males and females. In females, stimulates the maturation of eggs within the ovarian follicles, and stimulates secretion of estrogen by the ovaries. In males, FSH is required for sperm production
|
Follicle-stimulating hormone (FSH) A pit
|
|
stimulates ovulation and other sexual and reproductive activities
|
Luteinizing hormone (LH) a pit
|
|
together with other hormones initiates and maintains milk production in mammary glands
|
Prolactin (PRL) a pit
|
|
increases skin pigmentation
|
Melanocyte-stimulating hormone (MSH) a pit
|
|
Control the secretion of hormones by other endocrine glands
|
Tropic Hormones
|
|
synthesis/secretion of thyroxine
|
thyrotropin (t hormones)
|
|
cortisol secretion
|
adrenocorticotropin (ACTH) (t hormones)
|
|
ovulation/sexual and reproductive activities
|
luteinizing hormone (LH) (t hormones)
|
|
egg maturation, estrogen secretion, needed for sperm production in males
|
Follicle-stimulating hormone (FSH)
|
|
What is anterior pituitary controlled by?
|
Neurohormones produced by cells in the hypothalamus
|
|
stimulates thyrotropin release
|
thyrotropin-releasing hormone (TRH) [released by hypothalamus]
|
|
secretes neurohormones ADH and oxytocin
|
Posterior pituitary
|
|
increases amount of water conserved by the kidneys
|
ADH
|
|
stimulates uterine contractions that deliver baby and brings flow of milk to breasts
|
oxytocin
|
|
located below the larynx in front of the trachea
|
thyroid gland
|
|
Produces thyroxine and calcitonin
|
thyroid gland
|
|
stimulates secretion of thyroxine (T4-contains 4 iodine atoms)
|
thyrotropin
|
|
increases body's basal metabolic rate and stimulates amino acid uptake and protein synthesis
|
T4
|
|
enlarged thyroid due to lack of iodine (can also be due to hyperthyroidism)
|
goiter
|
|
produced by thyroid and lowers blood calcium
|
calcitonin
|
|
produced by parathyroid glands, raises it
|
parathyroid hormone (parathormone: PTH)
|
|
Secrets 3 groups of steroid hormones (mineralocorticoids, glucocorticoids, sex steriods)
|
Outer Cortex (adrenal gland)
|
|
secretes catecholamines (epinephrine and norepinephrine,) which stimulate the liver to supply glucose to the blood, as well as other fight-or-flight reactions.
|
Inner medulla (adrenal gland)
|
|
Aldosterone stimulates the kidney to conserve sodium and to excrete potassium, increasing blood volume
|
Mineralocorticoids (adrenal cortex)
|
|
- Cortisol decreases glucose utilization by most cells increasing blood glucose - important role in adaptation to stress.
|
Glucocorticoids (adrenal cortex)
|
