Intro Flashcards
1
Q
Classic endocrine glands
A
- Pituitary (anterior and posterior)
- Thyroid
- Parathyroid
- Adrenal
- Pancreas (islets)
- Gonads
2
Q
Hormones secreted by hypothalamus
A
- TRH
- CRH
- GnRH
- GHRH
- Somatostatin
- Dopamine
3
Q
Hormones secreted by anterior pituitary
A
- TSH
- FSH
- LH
- ACTH
- MSH
- GH
- Prolactin
4
Q
Hormones secreted by posterior pituitary
A
- Oxytocin
- ADH
5
Q
Hormones secreted by thyroid
A
- T3
- T4
- Calcitonin
6
Q
Hormones secreted by parathyroid
A
-PTH
7
Q
Hormones secreted by pancreas
A
- Insulin
- Glucagon
8
Q
Hormones secreted by adrenal medulla
A
- Norepi
- Epi
9
Q
Hormones secreted by kidney
A
- Renin
- 1,25-Dihydroxycholecalciferol
10
Q
Hormones secreted by adrenal cortex
A
- Cortisol
- Aldosterone
- Adrenal androgens
11
Q
Where do peptide and amino acid hormones bind?
A
Receptors on the membrane. They are hydrophilic and can’t cross the cell membrane.
12
Q
Where do steroid hormones bind?
A
Enter the cell and activate nuclear or cytoplasmic receptors.
13
Q
Characteristics of steroid hormones
A
- No storage pools
- Diffuse through cell membrane
- Receptor in cytoplasm or nucleus
- Regulate gene transcription
- Respond in hours to days
14
Q
Characteristics of peptide-amine hormones
A
- Storage pools in secretory vesicles
- Receptor on cell membrane
- Signal transduction cascade affects variety of processes
- Respond in seconds to minutes
- NOTE T3 and T4 can directly enter a cell
15
Q
Pseudohypoparathyroidism
A
- Molecular alterations in G proteins affect certain signaling systems
- Abnormality in subunit alphaS in a heterotrimeric G protein
- Impairment of PTH to regulate body calcium and phosphorus homeostasis
- Low serum Ca and high serum phosphate levels
- Have increased levels of PTH (it’s just not working correctly)
