Male and Female Genitalia Flashcards
uterine tube
oviduct or fallopian tube
extends from uterine horn and termiates in an infundibulum with fimbriae
regions of uterus
cervix (narrow canal with thick muscular walls), body (short), and uterine horns (long, paired)
vagina
canal connecting fornix (blind end near cervix) to vestibule
longitudinal folds when not expanded
vestibule of vagina
caudal to vagina
receives urethral opening
striated constrictor vestibuli muscle in wall
vestibular mucous glands
clitoris
3 parts
homologue of penis
glans - erectile tissue
body - fat in connective tissue
crus - erectile tissue in fibrous ct
vulva
left and right labia and vulval cleft
contrictor vulvae muscle in each labia
ventral fossa of clitoris
suspensory ligament of ovary
connects ovary to dorsal body wall
proper ligament of ovary
connects ovary to cranial uterine horn
round ligament of uterus
connects cranial uterine horn thru inguinal canal
opposes suspensory ligament of uterus
broad ligament of uterus
3 subdivisions
mesometrium
mesovarium
mesoalpinx
internal spermatic fascia
fibrous membrane bound to parietal vaginal tunic
external spermatic fascia
areolar ct within dartos
cremaster muscle
from internal abdominal oblique m.
on internal spermatic fascia
testes
produces spermatozoa and testosterone
tunica albuginea and visceral vaginal tunic over that
vessels branch for counter-current heat exchange
epididymis
stores and matures sperm
coiled duct with head, body, tail
ductus deferens
covered in visceral vaginal tunic and mesoductus deferens around that
goes through inguinal canal and penetrates prostate
enters urethra at clliculus seminalis
spermatic cord
ductus deferens, testicular vessels, vaginal tunic, spermatic fascia
accessory genital glands
prostate
bulbourethral gland in cats
penis
root (bulb and crus), body, free parts
penile urethra, erectile tissue, extrinsic muscles
corpus spongiosum
around urethra
begins as bulb at root
covered by bulbospongiosus muscle
corpus cavernosum
paired main erectile organ
forms crus at root, covered by ischiocavernosus muscle
replaced by os penis in free part
glans
pars longa and pars bulbus in dog covers whole free part
bulbus glandis responsible for “tie”
retractor penis muscles
paired, together at midline
smooth muscle
runs on ventral side of penis below bulbospngiosus muscle
erection
parasympathetic
inflow exceeds outflow
ejaculation
sympathetic
ductus deferens, smooth muscle in prostate, internal urethral sphincter all contract (prevent reflux in to bladder)
urethralis and extrinsic muscles contract to propel ejaculate
