Fact
The endocrine system involves many organs and tissues throughout the body that are responsible for producing and secreting hormones
Functions of Hormones
~regulate all bodily functions, even the production and release of other hormones
~are chemical messengers released into the bloodstream
~affect target cells that may be a great distance away from the endocrine gland or tissue that is releasing the hormone
~may be a peptide/amino acid, or a steriod compound.
What difference does it make if its a peptide/amino acid or a steriod compound
a peptide/amino acid is non-lipid soluble (need receptors
a steriod compound is lipid soluble (can diffuse)
Compare exocrine and endocrine glands
exocrine~ has a duct
endocrine~ ductless
What are some examples of exocrine glands
sweat, tear, saliva
How are the endocrine system and nervous system similar in function?
pituitary is like the hypothalamus
how do they differ?
neurons can secrete
Fact
there are very close ties b/w the nervous system and the endocrine system. the hypothalamus is responsible for producing several hormones, especially "releasing hormones" to control other endocrine tissue. Neurosecretory cells are neurons which secrete chemicals which can function as hormones
anterior pituitary
secretes
posterior pituitary
produces its own hormones
What are the major hormones released by the anterior pituitary?
TSH- thyroid stimulating hormone
ACTH- stimulates adrenal gland
Prolactin- production of milk
What are the major hormones released by the posterior pituitary?
oxytocin- stimulates muscles in uterus/mammary glands
ADH- effects kidneys (to conserve water)
Where is insulin produced and what is its effect on the body?
Pancreas (beta cells)
lowers the blood sugar
Where is Glucagon produced and what is its effect on the body?
pancreas (alpha cells)
regulates glucose levels
Where is ADH produced and what is its effect on the body?
in the hypothalamus neuron
effect kidneys (to conserve water)
Where is Oxytocin produced and what is its effect on the body?
in the hypothalamus neuron
stimulates muscles in the uterus/mammary glands
Where is Growth hormone produced and what is its effect on the body?
entire body
Where is Prolactin produced and what is its effect on the body?
in the anterior pituitary
stimulates the production of milk
Where is Calcitonin produced and what is its effect on the body?
thyroid
controls of calcium levels by reducing calcium in the bloodstream
Where is Thyroxine produced and what is its effect on the body?
thyroid
stimulates metabolic rate, body temp, and growth
Where is Parathormone produced and what is its effect on the body?
thyroid
increases calcium
Where is Epinephrine produced and what is its effect on the body?
adrenal gland
increases levels of sugar and fatty acids, increases metabolic rate
