which cell protects the developing sperm from antibodies produced by immune cells
sertoli cells
If sperm are fully mature but not motile, which structure do you expect is not functional?
epidydimys
which structure transports sperm to the prostate?
vas deferens
which hormone would be deficient in a male if he is exposed to a toxin that destroys leydig cells?
testosterone
why is semen alkaline?
because acid will destroy sperm
what hormone in male regulation is released by the hypothalamus?
GnRH
how does GnRH get from the hypothalamus to the anterior pituitary gland?
by blood vessels
what cells release FSH and LH in the anterior lobe of the pituitary gland?
gonadotrophs
where does ABP go after produced in the testes?
into the lumen of the seminiferous tubules
Blocking which type of receptors would result in reduced testosterone levels?
lh receptors on leydig cells
Which hormone stimulates sertoli cells to release ABP?
FSH
Parasympathetic neurons release _____ into arteries supplying erectile tissue leading to ______
NO, vasodilation
_________ innervates the blood vessels that supply erectile tissue
parasympathetic N.S
NANC (nonadrenergic noncolinergic) neurons do not release norepinephrine or acytelcholine, but the do release ____
NO (endothelial cells tend to release NO)
What is NO effect on smooth muscle cells?
causes cGMP to be produced
what does cGMP do?
gets calcium out of the cytoplasm... therefore muscle relaxes ... blood flow increases which causes blood flow to occur
what enzyme breaks down cGMP?
PDE5 phosphodyesterase (if you give someone a drug that destroys the PDE5, then cGMP will not break down and erection will occur.
what do erectile dysfunction drugs inhibit?
PDE5 phosphodyesterase
what does GnRH bind to?.... what hormones does it then secrete into the blood?
GnRH (which comes from hypothalamus) binds to gonadotrophs... in then secretes LH and FSH into the blood
what are the functions of prostaglandins?
to decrease the viscosity of seminal fluid
causes reverse peristalsis
what do leydig cells secrete?
testosterone
what does testosterone cause?
stimulation of spermatogenesis
bone and muscle growth
male secondary sex characteristics
secretion of ______ from the sertoli/sustentacular cells in the testes creates a negative feedback loop in the anterior pituitary gland
inhibin
which hormone stimulates sertoli cells to produce ABP?
FSH
where does the bacteria of clamitia and ganorea reside in the penis?
in the glands of littre
what gets calcium out of the cytoplasm?
cGMP
erectile dysfunction drugs inhibit _____
phosphodyesterase
the two layers of the uterine wall are __________ and _________
endometrium, myometrium
the two layers of the endometrium are the ____ and the _____.... which layer remains throughout menstrual cycle?
functional ... basal...... basal layer remains... functional gets sloughed off and rebuilds
what type of epithelium does the vagina have?... what type of epithelium does the cervical canal have?
non keratinized stratified squamous.... protects from abrasion....simple columnar
the most inferior part of the uterus is?
the cervix
what hormone is added to estrogen after ovulation?
progesterone
what cells produce the secretions in a lactating womans breast? (they surround the lobule... increase the pressure)
myopithelial cell (milk letdown with production of oxytocin)
what is the first secretion produced by the mammary glands? what does it contain?
colostrum.... it contains proteins, carbohydrates, antibodies
what is milk let-down caused by?
oxytocin stimulates the myoepithelial cells squeezing out milk into the ducts...
suckling stimulates nerves in the ___ which stimulates the _____ which stimulates the ______ to release _____ which stimulates contraction of the _______
nipple... hypothalamus... posterior pituitary (neurohypophysis)...releases oxytocin....contraction of the myoepithelial cells
this benign breast disorder ________ is a slow growing mass of epithelial and connective tissues (solid mass)... it is painless and there are no changes in size with menstrual cycle
fibroadenoma
this benign breast disorder _______ is a proliferation of the connective tissue stroma and cystic formation of ducts (fluid filled)... it results from increasing hormone levels. it is painful (masalgia)
fibrocystic
where do breast tumors arise most of the time?
in the ducts (ductal epithelium)
what happens in ductal hyperplasia? what is the problem with it?
an increase in number of cells within the duct wall.... it will metastacize throughout the body.
