BL Endocrine Flashcards
Location of the pituitary gland
Below the hypothalamus at the base of the brain
Location of the thyroid gland
Anterior to the trachea
Location of the parathyroid gland
On dorsal surface of the thyroid gland
Location of the adrenal gods
On top of each kidney
Location of the pancreas
Left of and posterior to the stomach
What does the anterior pituitary gland secrete?
TSH
ACTH
LH
FSH
GH
What does the posterior pituitary secrete?
ADH
Oxytocin
What does the thyroid gland secrete?
Thyroxine - T4
Triodothyroinine - T3
What does the parathyroid gland secrete?
Parathormone PTH
What does the adrenal gland secrete?
Adrenaline + noradreline
Corticosteroids, glucosteroid + mineralcorticoids
What are the types of hormones?
Glycoproteins + peptide
Steroid
Amino acid derived - catecholamines + thyroid
Lipid
For steroid hormones outline:
- synthesis and storage
- transport in blood
- location of receptor
- response to receptor-ligand binding
- examples
- made on demand from precursors
- bound to carrier proteins
- cytoplasm or nucleus
- activation of gens for transcription + translation
- e.g. oestrogen, androgen, cortisol
For glycoproteins + peptides ormones outline:
- synthesis and storage
- transport in blood
- location of receptor
- response to receptor-ligand binding
- examples
- made in advance + stored in secretory vesicles
- dissolved in plasma
- cell membrane
- activation of 2nd messenger systems
- e.g. insulin, glucagon, ACTH, PTH
For thyroid hormones outline:
- synthesis and storage
- transport in blood
- location of receptor
- response to receptor-ligand binding
- examples
- made in advance + store in secretory vesicles
- bound to carrier proteins
- nucleus
- activation of genes for transcription + translation
- e.g. T3+T4
For catecholamines hormones outline:
- synthesis and storage
- transport in blood
- location of receptor
- response to receptor-ligand binding
- examples
- made in advance + stored in secretory vesicles
- dissolved in plasma
- cell membrane
- activation of second messenger systems
- e.g. adrenaline, noradrenaline, dopamine
