reveiw Flashcards
A skin sack which contain the testes
scrotum
this hormone (abbv) is released by the hypothalamus which causes the anterior pituitary gland to release LH and FSH
GnRH
A structure attached to the side of a testicle which contains numerous tubules
epididymis
breast milk contains numerous ______ which can help protect newborns from various diseases
antibodies
The production of oxytocin during labour is an example of _______ feedback system
positive
Location of erectile tissue in females; contains many nerve receptors; analogous to the penis in males
clitoris
The follicle which releases an egg from the ovary turns into the ______ luteum which begins releasing hormones
 corpus
The name of the fluid which is ejaculated from the penis
Semen
The birth canal; also a receptacle for the penis during copulation
vagina
the ________ gland secretes an alkaline fluid into the semen
prostate
The seminiferous tubules are so long in order to increase the _____________ for development of large numbers of sperm (2 words)
surface area
The female sex cell
egg
The hormone (abbv) is released by the anterior pituitary and causes a sex organ to release either the male or female sex hormones (depending on the individual)
LH
A tube leading from the bladder to the outside environment
urethra
the ________ phase occurs second in the menstrual cycle - when the corpus luteum is releasing hormones
luteal
also known as the fallopian tube, this structure leads from the ovary to the uterus
oviduct
mothers produce _____ to feed their newborn babies
milk
The release of the lining of the uterus during the first day of the female cycle
 menstruation
The female hormone which dominates in the latter portion of the menstrual cycle
progesterone
the _________ phase of the menstrual cycle occurs first; this is when the follicle is developing in an ovary
follicular
The female hormone which dominate in the early part of the menstrual cycle
estrogen
the ___________ tubules are the location of spermatogenesis
seminiferous
The male sex cell
sperm
these glands provide milk to the newborn baby
mammary
_________ is produced by the breasts in the first couple of days of breast-feeding - it contains more protein and less fat than milk
colostrum
A collective term referring to all of the external female genitalia
vulva
organ used for the storage of urine
 bladder
The lining of the uterus
endometrium
The male sex hormone which induces sperm production and male secondary sexual characteristics
 testosterones
As sperm levels in the testes rise, this hormone is produced by the Sertoli cells which acts on the hypothalamus
inhibin
these finger like structures waft the egg cell from the ovary into the oviduct
fimbriae
this hormone is responsible for uterine contractions during labour and milk production postpartum
 oxytocin
rhythmic contractions of smooth muscle and vessels (example, vas deferens) to propel material through those vessels
peristalsis
this hormone (abbv), secreted by the anterior pituitary, is responsible for initiating the production of either sperm or eggs (depending on the individual)
FSH
both sperm and eggs are haploid because they were formed via the process of _______
meiosis
the hormone ______ (abbv) is responsible for maintaining hormone levels to prevent menstruation during pregnancy
HCG
these cells help to “nanny “or “nurse” sperm along to for maturity
sertoli
 The _______ glands secretes a slippery fluid sometimes referred to as pre-ejaculate
 cowpers
hormones which caused the uterus to contract
 prostaglandins
sometimes called the womb - this is where the fetus develops
 uterus
an organ which forms in the uterus during pregnancy
 placenta
The female sex organ which produces eggs and hormones
ovary
The expulsion of semen from the penis
ejaculation
The release of an egg on day 14 of the cycle due to a surge in luteinizing hormone
ovulation
The ejaculatory ______ carry semen from the seminal vessel to the urethra
duct
_______ muscle is found in the various tubules to propel their contents
 smooth
The male copulatory organ
penis
A membrane which may cover the opening of the vagina
hymen
The uniting of the nuclei of a sperm and an egg is considered the moment of _________
 fertilization
Inhibin being produced as sperm quantities increase in the testes is an example of a ________ feedback system
negative
This substance fills the penis and clitoris during arousal
blood
The location of sperm and testosterone production
testes
in order to mature properly, sperm must form in an environment that is _______ than the normal internal body temperature
cooler
The typical female menstrual cycle last twenty _____ days
eight
paired organs which secretes fructose and prostaglandins (two words)
seminal vesicle
The fertilized egg is known as a ______
zygote
_________ tissue in the penis fills during arousal
 erectile
paired tubes with carries sperm from the testes to seminal vessels
Van deferens
______ cells are responsible for the production of testosterone
interstitial
The inner portion of the labia is known as the labia _____
minora
found at the top of the vagina, this is the opening to the uterus
cervix
The labia ______ are the outer folds of the labia
majora
A human sperm or egg contains twenty _____ chromosomes
three
there are large numbers of mitochondria in the _______ of a sperm
mid-piece
