endocrine system and nervous system
|
use communication to maintain homestasis
|
|
|
|
endocrine and nervous systems
|
use chemicals as messengers
|
|
|
|
endocrine system
|
communication is much slower to start,less specific as to its target, and takes longer to end.
|
|
|
|
what are hormones
|
hormones are chemicals that travel to their target tissue and tell them to do something
|
|
|
|
target tissue
|
has receptors for a hormone based on shape
|
|
|
|
pineal gland
|
produces biological rhythms
|
|
|
|
thyroid gland
|
located below the larynx
two lobes connected by anterior isthmus |
|
|
|
thyroid hormone (T4 and T3)
|
uses iodine for production
|
|
|
|
thyroid hormone
|
increase metabolic rate
promotes protein synthesis enhances neuron function |
|
|
|
calcitonin
|
another hormone produce by the thyroid gland
lowers blood calcium by stimulating calcium deposition by osteoblasts in bones |
|
|
|
pancreas
|
produce glucagon and insulin
|
|
|
|
glucagon
|
raises blood glucose
|
|
|
|
insulin
|
lowers blood glucose
|
|
|
|
two adrenal glands
|
one on top of each kidney
|
|
|
|
adrenal glands consist of two portions
|
the inner adrenal medulla
the outer adrenal cortex |
|
|
|
what are Gonads
|
ovaries and. testes
|
|
|
|
what are the three categories of hormones base upon chemical composition
|
steroids, amino acid derivatives, and protein
|
|
|
|
what is steroid hormones
|
derived from cholesterol
estrogen they pass through the cell membrane to reach receptor within the cell |
|
|
|
amino acid derivatives
|
building blocks of protein
epinepherine epinepherine can not pass through the cell membrane |
|
|
|
What can you find the adrenal glands
|
on top of the kidneys like hats
|
|
|
|
protein hormones
|
derive from chains of amino acids
example: insulin these hormones are too large to pass through the plasma membrane. |
|
|
|
target tissues
|
receptors for hormones can be on the cell membrane or inside the cell
water soluble hormones bind to receptors in the out side of t h a cell activates second messenger systems lipid soluble hormones(steroids)bind receptors inside of the cell |
