Communication Flashcards
(26 cards)
nervous system
regulation of body functions
rapid, short acting effects
Endocryn system
regulation of body function
Acts slowly with long lasting effects
Glands secrete hormones into the blood -Travels to target organ, - Regulates activity
glands
parts of the body that makes a message and sends it to another part of the body
stereroid hormones
Made from cholesterol
Pass through cell membrane of target cell
non stereroid hormones
Made from proteins
Attach to receptor outside of cell to send message into cell
dopamine
Regulates movements, attention, learning, and emotional responses (desire/pleasure/satisfaction) - “Reward System”
Seratonin
mood stabalizer, arousal/happiness, digestive system, nausea, sexual function
Epinephrine / norepinephrine / adrenaline
Fight/Flight, arousal, exhilaration, changes size of blood vessels
Cortisol
Stress hormone, helps wih metabolism, anti-inflammatory, regulates blood pressure
SSRI
Selective Seratonin Reuptake inhibutor
Hypothalamus in reference to nervous systems
master gland of body regulation
controls nervous and endocryn system
Can detect levels of hormones and can send messages to the pituitary gland which sends messages to organs
negative feedback loop
homeostasis - balance
most of body works on
A-B-C
Hypothalamus → pituitary → end organ
if not enough of C body makes A start producing more
If enough of C then A shuts off
Positive Feedback loop
A-B-C
Hypothalamus → pituitary → end organ
A never shuts off so exponential growth of C
2 functions of body that perform positive feedback loop
ovulation and birth
Sexual Feedback
Puberty begins with release of ______ every _______to start hormone release
GnRH
60-90 minutes
Testes
endocryn glands with 2 functions
- secrete testosterone
- make sperm
Testes hormones
ova hormones
Follicle Stimulating Hormone (FSH)
Origin: Pituitary
Function:
“Regulate ovarian function and maturation of ovarian follicles” (2013, p. 82).
“Stimulates sperm production in testes” (2013, p. 114).
Luteinizing Hormone (LH)
Origin: pituitary
“Assists in production of estrogen and progesterone, regulates maturation of ovarian follicles, triggers ovulation” (2013, p. 82).
“Stimulates testosterone production in interstitial cells within testes” (2013, p. 114).
Gonadotropin-Releasing Hormone (GnRH)
Origin: Hypothalamus
Function: “Promotes maturation of gonads, regulates menstrual cycle” (2013, p. 82).
“Stimulates pituitary during sperm production” (2013, p. 114).
Estrogen
Origin: Ovaries, adrenal glands, placenta (during pregnancy)
Function: “Promotes maturation of reproductive organs, development of secondary sex characteristics, and growth spurt at puberty; regulates menstrual cycle; sustains pregnancy; maintains libido” (2013, p. 82).
Testosterone
Origin: Adrenal glands, ovaries, testes
Function: “Helps stimulate sexual desire” (2013, p. 82).
“Stimulates sperm production in testes, triggers development of secondary sex characteristics, regulates sex drive” (2013, p. 114)
