Does the nervous system or the endocrine system react faster to external/internal stimuli?
nervous system
What are 2 major groups of hormones and what are their derivatives?
1. peptide (derived from proteins and catecholamines)
2. steroids (derived from cholesterol)
Hormones can react with cells that have what on their cell surface?
receptors
Do peptide or steroid hormones react faster?
peptide hormones
True or false: Endocrine glands contain ducts and secrete their contents directly into an epithelial
lining
False
endocrine glands are ductless, secreting their contents directly into the bloodstream
True or false: the hypothalamus and pituitary glands are in the abdomen
False
they are located in the brain
the adrenal glands are found on top of the _____________.
kidneys
name 3 secondary endocrine organs
heart, thymus, kidneys, gonads (testes & ovaries)
Describe homeostasis in the body
(set-point) is a range in which the body acts to maintain all its levels for function.
during negative feedback a hormone level is high. What happens to hormone production?
, the brain detects the hormone level is too high and hormone production is shut off
the action of oxytocin (OXT) works through positive or negative feedback?
positive feedback
Why are the neurons in the hypothalamus called neurosecretory cells?
they are cells that respond to neurotransmitters and produce hormones
axons travel from the hypothalamus terminate in what region of the brain?
posterior pituitary
The posterior pituitary gland stores what 2 main hormones?
ADH and OXT
(antidiuretic hormone and oxytocin)
What does ADH do in the body?
ADH promotes the reabsorption of water from the collecting ducts, which receive urine produced by
nephrons within the kidneys.
As the blood becomes dilute, the hormone no longer is released until it is needed again
What hormone stimulates the release of milk from the mammary glands?
oxytocin (OXT)
What are the primary endocrine organs?
hypothalamus
pituitary glands
pineal gland
thyroid gland
parathyroid gland
adrenal glands
pancreas
What major hormones are secreted from the anterior pituitary gland?
growth hormone (GH)
prolactin (PRL)
melanocyte stimulating hormone (MSH)
thyroid stimulating hormone (TSH)
adrenocorticotropic hormone (ACTH)
follicle stimulating hormone (FSH)
luteinizing hormone (LH)
What major hormones are secreted from the posterior pituitary gland?
