Endocrine System Flashcards
water soluble hormones communicate with cells how?
Cannot cross the plasma membrane.
Instead act on receptors in the membrane which then trigger cell response.
lipid soluble hormones communicate with cells how?
enter the cell and acts on receptors inside the cell to trigger a response.
insulin is released as a response to increased blood glucose. This is known as a _ stimulus?
humoral stimuli (response to changing levels of a substance within blood)
What does neural stimuli do?
nerve fibres stimulate hormone release.
sympathetic nervous system stimulates adrenal medulla to release norepinephrine and epinephrine
What does hormonal stimulus do?
hormones released from one gland trigger another gland to release hormones.
Which part of the pituitary gland makes and secretes hormones?
anterior pituitary lobe
Where are hormones made by the hypothalamus stored?
posterior pituitary lobe
where is oxytocin stored and what is it’s function?
Posterior pituitary gland
Stimulated by stretching of cervic
Action: childbirth contractions
When you are dehydrated the posterior pituitary gland releases this hormone to target kidneys and increase water reabsorption in the blood
antidiuretic hormone (ADH)
anterior pituitary gland stores which hormones?
Growth hormone (GH) Thyroid stimulating hormone (TSH) Luteinising Hormone (LH) Follicle stimulating hormone (FSH) Prolactin (PRL)
