two glands located on either side of urethra. scretes thick mucus acts as lubricant for sperm
called
cowper's glands in humans

all species except the cat ahve cranioventrally directed penis
CF for penis is pen/i and priap/o
runimants and swine achieve an ereciton by straighten
the sigmoid flexure. an S shaped bend in the penis.

uterine tubes also called
oviducts and fallopian tubes
CF for uterine tubes is
salping/o, which means tube
infundibulum
distal end of each uterine tube; a funnel shaped opening
fimbriae
fringed extensions inside the infundibulum
fertilization
usually occurs in the uterine tube
proximal end of each uterine tube is connected to uterine horns.
dogs have uterine horns so puppies line up.
uterus
thick-walled hollow organ w/ muscular walls and a musous membrane lining housing developing embryo
uterus
CF is hyster/o, metr/o, metri/o and uter/o
cornus

cornu means horn
horn; cranial end of uterus has two horns travel toward the oviducts
some animals are bicornuate - have two uterine horns

cervic/o means neck
neck; caudal portion of uterus extends into vagina
uterus composed of three major tissue types
perimetrium: membranous outer layer
myometrium: muscular middle layer my/o CF for muscle
endometrium: inner layer
endo - prefix for within
cervix
caudal continuation of uterus and marks cranial extent of vagina
contains ring-like smooth muscle called sphincters
CF is cervic/o
vagina
CF is colop/o and vagin/o
hymen
membranous fold of tissue may partially or completely cover the external vaginal orifice
vulva
female external genitalia or pudendum
consists of vaginal orifice, vestbular glands, clitoris, hymen and urethral orifice
vulva
CF is vulv/o and episi/o
the perineum is the region between the vaginal orifice and anus in females
labia
flashy borders of vulva occasionally called lips
vestibular glands also know as bartholin's glands (in primates)
found in bovine, feline, occasionally ovine species; secrete mucus to lubricate vagina

clitoris is analog of glans penis of the male
sensitive erectile tissue
mammary glands
or mammae
milk producing glands in females.
in large animals also called udder
each single gland is associated w/one nipple
lact/i means milk
CF for mammary glands is mamm/o and mast/o
pregnancy
CF pregn/o
cyesis also means pregancy
