memories terms (19 cards)
skull and mennengies
- The skull and the mennengies both protect the brain.
- when you hit your head, the brain will actually hit the inside of you skull. This causes w=swelling of your brain.
- the mengies can be infected which cause meningitis.
how are the NS and ES similar in use
they both use neurotransmitters and hormones, they are used to send signal between nerves as neurotransmitters and as help body function as a hormone
the endocrine system
The endocrine system controls all of the hormones, what makes and stores them.
how do hormones work
hormones are chemical that are released into the bloodstream. Every cell recives but only some of them have receptors that can do stuff with them. ,
- they can activate multiple tissues at once. Long lasting and slower then the nervous system
Tropic hormones
tropic hormones are hormones that activate other hormones. The other hormones will be released and trigger their targeted tissue.
kid of instructor. Mr magreal telling Mr. Ha to grade the tests.
Hormones can be two things
STeroid (lipid soluble)
and Non-steroid (water soluble
What are Steroid hormones
-steroid hormones are permeable through the cell membrane
Steroids can attach to protein receptors IN the cell
- they cause genes to activate
ex, Estrogen, testosterone, Cortisol
What is a non-steroid hormone
- they are not permeable
- they can attach to the cell membrane protein receptors
- ex norepinephrine
Pituitary glands and both parts
- small ball in the brain that stores alot of the hormones needed for bodily function.
-two part, posterior and anterior
Anterior pituitary gland hormones
- (FSH) Follicoler stimulating hormones
- (HGH) Human Growth hormone
-(PRL) Prolactine - (TSH) Thyroid stimulating Hormone
- (ACTH) Andreocortico-tropic hormone
Anterior Pituatry gland
- Oxytocin
- (ADH)Antidiuretic
Follicle Stimulating Hormone
Target tissue-Ovaries and testes
Effects -Makes eggs and sperm
Human Growth Hormone
TT- Bones muscles and everything else
Effects- Growth, healing, and triggers puberty
What are the three conditions with HGH
Too little (Pituatry dwarfism) -causes childlike feutrures in adults, infertility.
treatments-giving more HGH
Too much (Gigantism)
Effects: really tall and delicate. Treatment: if caught early removal of the Pituatry heart.
Acromegaly-Too much after puberty causes thick bones, especially in face and fingers
Prolactin
Causes production of milk
the more the baby suckle more Prolactine is released and more milk is made (positive feedback system)
Adrenal cortical tropic hormone
causes adreanal gland to produce stress hormone to trigger flight or flight
Thyroid stimulating Hormone
Tropic hormone that causes the thyroid to produce thyroxin.
Thyroxin set bodies metobalic levels
Too much-weathloss,nervousness, too hot elveated pulse, fatigue
(Hyperthyrodism)
Too little-weithgain, feeling cold,muscel weaken, puffy face
Oxytocin
Bonding hormone, Targets utarine lining and helps with contraction and child birth (positive feedback system) feeling love for breatfeeding
Antidiuretic hormone
Targets kidneys.
used to maintain tonic levels
Increase ADH=less h2o=concentrated urine
Decrease ADH=More H20=diluted pee
