Endocrinology Flashcards
What is the definition of an exocrine cell?
A cell which secretes substances via ducts which then release onto epithelial surfaces
What is an endocrine cell?
A cell which produces a hormone which is released into the bloodstream and acts at a distant site
Give examples of amine hormone?
Adrenaline
Noradrenaline
Dopamine
Give examples of peptide hormones?
Pituitary hormones
Insulin
Peptin
Ghrelin
Give examples of steroid hormones?
Glucocorticoids
Mineralcorticoids
androgens
Progesterone
Amine and peptide hormones must work through signal transduction. What kind of receptor is most commonly used by these hormones?
G protein coupled receptor
Give examples of hormones which work via tyrosine kinases?
Insulin
IGF-1
Prolactin
What type of hormone can pass directly through the plasma membrane to act intracellularly and combines with its receptor to act as a transcription factor regulator?
Steroid hormones

What hormones are released by the anterior pituitary?
ACTH LH FSH TSH GH Prolactin
What hormones are produced by the thyroid gland?
Thyroxine (T4)
Triiodothyronine (T3)
Which pituitary hormone stimulates the thyroid?

Which pituitary hormone stimulates the adrenal glands?
ACTH
What hormones are produced by the adrenal cortex?
