Hormone basics
This hormone class is made from cholesterol.
Steroid
Hormones have opposing effects
Antagonism
This portion of the pituitary has a neural connection to the hypothalamus
Posterior pituitary
What does IGF stand for
Insulin like growth factor
A critical aspect of endocrine reflexes
Negative feedback
This hormone class is synthesized by linking amino acids
Peptide
The effect of 2 or more hormones on the same parameter is greater than additive
Synergism
Hormones released by posterior pituitary
This anterior pituitary hormone is associated with breast milk production
Prolactin
What are the three patterns of endocrine pathology
Hyposecretion, hypersection, and abnormal tissue responsiveness
This hormone class is synthesized from either tyrosine or tryptophan
Amine
One hormone is needed for another to exert its full effect
Permissiveness
This posterior pituitary hormone is a peptide hormone
ADH/Vasopressin
This hormone has a surge that triggers ovulation
Luteinizing hormone (LH)
Begins in the final endocrine gland in the pathway
1° pathology
These are the primary sources of steroid hormones
Adrenal cortex and gonads... also placenta
Bundles of cells in the pancreas, called the _________, contain two kinds of cells, ___ cells and ___cells
islets of Langerhans, alpha, and beta
This posterior pituitary hormone works on smooth muscle and is involved in the milk let-down reflex
Oxytocin
CRH stimulates the anterior pituitary to release this hormone, which then acts on the adrenal cortex
Adrenocorticotrophic hormone (ACTH)
This type of pathology begins in the tissue producing the trophic hormone
2° pathology
These two amine hormones work more like steroid hormones, while ____ work more like peptide hormones
T3and T4. Catecholamines
These two pancreatic hormones are antagonistic: beta cells release one when blood glucose rises, while alpha cells release the other when blood glucose drops
Insulin and glucagon
This portion of the pituitary is true endocrine/ glandular tissue and release classic hormones
Anterior pituitary
Match the hypothalamic hormones to their anterior pituitary hormones: TRH to __, CRH to __, GHRH to __, and GnRH to ___
TRH to TSH, CRH to ACTH, GH to GHRH, and GnRH to FSH/ LH
A trophic hormone does this to the final hormone in an endocrine pathway
Stimulates the release of the final hormone
