LSR Flashcards
exocrine glands
Makes hormones that leaves the body through tubes
endocrine glands
makes hormones that stay in the blood
What cells do hormones affect? What are those cells called?
Hormones only affect cells that have receptors for them
Those cells are called target cells
What system can start hormone production?
nervous
Give an example showing negative feedback (ab)
Thyroid and Pituitary
testosterone
male sex hormone
progesterone and estrogen
female sex hormones
testes
sperm/testosterone
urethra (female)
pee & discharge passageway
urethra (male)
urine and sperm passageway
uterus
where fertilized egg attaches, where placenta forms and embryo and fetus develop
cervix
opening at bottom of uterus where baby is held
clitoris
site of female sexual arousal - kind of like penis
menstrual cycle
when the extra lining that was built up in the uterus in case an egg is fertilized is released-with some blood
hormones
a chemical made by the body
each hormone works on certain
tissues/organs called targets
made in endocrine glands
in which part of a cell do you find chromosomes?
nucleus
what kind of cell has no chromosomes?
red blood cell b/c they have no nucleus
what pair of chromosomes makes a boy? A girl?
xy, xx
What is the path of a sperm from where it is produced until it meets an unfertilized egg.
testes, epididymis, sperm duct, urethra, vagina, uterus, oviduct (fallopian tube)
diff btw sex and gender?
sex is biological gender is how society portrays you
menopause
when a women no longer menstruates
ovulation
when the egg is released from the ovary
secrete
to send out
masturbation
handling genitals for pleasure
wet dream
when sperm and semen is ejaculated during sleep
erection
when the penis becomes engorged with blood and stiff so if can enter the vagina
ejaculation.
when sperm and semen are sent out of the body in spurts
fertilization
when egg and sperm join in the females body.
arousal
Sexual excitement where the genitals swell with blood
Why does the egg and sperm only have 23 chromosomes when a cell needs 46?
Because when the combine to make a baby the cell will combine the 23 chromosomes from the egg and sperm and the baby cell will actually have 46 chromosomes. If this did not happen then the amount of chromosomes in someones body would multiply by 2 every time they had a baby.
Why do endocrine glands have receptors?
Because without receptors the hormone wouldn’t know where to go yet with receptors its like a key and lock.
secondary (both)
secondary (male)
secondary (female)
hair, voice
beard, shoulders
breast, hips
primary (male)
primary (female)
testes, penis
vagina, ovaries
what can go from the mother to the baby by diffusing from the mother’s blood to the baby’s
amino acids, vitamin c, glucose, carbon dioxide, alcohol, fatty acids, oxygen, glycerol, vitamin a
difference between puberty and adolescence
puberty is the physical and sexual maturation. adolescence is all maturation.
scrotum
cools and holds testes
prostate
produces semen and neutralizes the acid from your pee
seminal vesicles
produces semen
sperm duct
carries mature sperm into the urethra
ovary
produces eggs, estrogen, and progesteron
oviduct/fallopian tube
takes eggs from the ovary to the uterus
clitoris
main site of sexual arousal in females
vagina
passageway for babies, menstrual flow, and the penis/sperm
labia
covers and protects the vaginal opening
epididymis
where the sperm matures
how long do sperm live inside the female
3-5 days
how long do eggs usually live after ovulation
1-2 days
where is FSH produced
pituitary
where is estrogen produced
follicle in ovary
where is LH produced
pituitary
where is progesterone produced
corpus luteum/ overy
where is membrane hormone produced?
membrane of embryo
FSH
STIMULATES FOLLICLE AND EGG
estrogen
negative feedback/uterus lining
LH
ovulation, heals follicle
progesterone
thicken uterus, stop FSH and LH
membrane hormone
keeps corpus luteum alive
fontanel
space between skull bones of an infant/fetus
placenta
attached by umbilical cord. also called afterbirth
during the first 8 weeks of development, the baby is called an ______ whereas after this it is known as a ______.
embryo, fetus
Does the blood of the mother and the developing baby mix
no
