anterior pituitary
-thyrotropin
-adrenocorticotropin
-luteinizing hormone ( LH)
-follicle -stimulating hormone (FSH) |
|
Definition
has portal blood vessel
gland cell
7 peptide hormone
hGH- human growth hormone-cell growth
TSH- thyroid stimulating hormone
ACTH- adrenalcorticotropic hormone- stim. adrenal cortex
FSH- follicle stimulating hormone
-LH- luteinizing hormone, stim. ovulation & other sexual and reproductive activities
-PRL- prolactin-milk production
MSH- melanocyte stim. hormone-skin pigment
secret 4 tropic hormone
-thyrotropin( synth. / secretion of thyroxine
-adrenocorticotropin- cortisol secretion
-luteinizing hormone ( LH)- ovulation/ sexual & reproductive activities
-follicle -stimulating hormone (FSH)- egg maturation, estrogen secreation, sperm production |

Definition
neural cell
-has axons connected to hypothalamus
neurohormones:
-vassopressin: ADH,antidiuretic hormone, reabsorb H2O when dehydrated
-oxytocin: facillitates birth breast feeding, and acts as a neurotransmitter in the brain |

Term
thyriod
- thyroxine
-calcitonin |
|
Definition
thyroxine T4- contain 4 iodine atoms
-inc body basal metabolic rate
-calcitonin- lower blood calcium
osteoblast- creates bone, storing ca++ |
|
|
Term
parathyroid
-parathyroid hormone ( PTH) |
|
Definition
PTH- parathyroid hormone- increase blood Ca+
osteoclast- break bone releasing ca++ |
|
|
Term
|
Definition
primary center gland of lymphatic system
-secretes thymosin, an immunologic hormone, and it's main function is to develop immature T-cells into mature immunocompetent T-cells. |
|
|
Term
adrenals
outer cortex- ( mineralocorticoids, glucocorticoids, sex steroids)
-inner medulla- catecholamines ( epinephrine and norpinephrine)- stimulate glucose in blood and fight/ flight rxn |
|
Definition
mineralocorticoids- aldosterone stimulated the kidney to conser sodium and secrete potassium, inc blood volume
glucocorticoids-cortisol dec. glucose utilized by most cells, increasing blood sugar, imortant role in adaptation of stress |
|
|
Term
|
Definition
-function as both endocrine/ exocrine gland
"pancreatic islet (islets of langerhans)
-alpha cells secrete glucagon ( inc blood sugar)
-beta cell secrete insulin ( dec. blood sugar) |

Definition
| testosterone secreted by..... |
|
|
Term
|
Definition
| secrete insulin, found in pancreas, liver to undergo sugar processes |

Term
|
Definition
| amino acids and etc ---> glucose |
|
|
Term
|
Definition
-lack of insulin
-autoimmune lead to destruction of the pancreatic b cells and inability to secrete insulin |
|
|
Term
|
Definition
-nothing wrong with insulin secretion, but insulin receptors are less sensitive than normal
complication of diabetes
-glucosuria, osmotic effect cause water to leave the cells= polyuria and polydipsia
-inc break down of fatty acids acids= production of keytone bodies( keto acids)
-lead to electrolyte imbalance, and affect brain= coma/ death
-blindness, kidney failure, deterioration of blood flow to extremities |
|
|
Term
|
Definition
accelerate uptake of glucose from blood into skeletal muscle
-accelerate glycogenesis( glucose to glycogen)-speed up protein synthesis
- acc. lipogenesis ( glucose or amino acid ---> fatty acid)
-dec. gylcogenolysis
-inhibit gluconeogenesis |
|
|
Term
|
Definition
-stimulate glycogenolysis in liver ( glycogen--> glucose)
- stimulate gluconeogenesis in liver (amino acids, lactate, etc. ---> glucose |
|
|
Term
|
Definition
outer cortex-
-mineralocorticoid- conserve Na+ and excrete K+
-glucocorticoids- secreate cortisol, dec glucose utilization, directedin more important part of body to handle stressful situation
-sex steroids
inner medulla-
secretes catecholamines ( epinephrine and norepinephrine) stimulate the liver to supple glucose to the blood |
