Reproductive System Flashcards
Containing the testes and serving as a thermoregulator
Scrotum
Loop system of veins and arteries that allows heat exchange
Pampiniform plexus
Porch or diverticulum of the abdomen
Scrotum
Organ of copulation in males
Penis
4 parts of penis
Glans penis
Body
Crura
Sigmoid flexure
Free extremity; soft terminal portion of the penis
Glans penis
Main portion of penis; formed by urethra and the erectile tissue
Body
Curving of the penis
Sigmoid flexure
Erectile tissues of penis
Corpora cavernosa
Corpus spongiosum
Engorges with blood to cause erection and extension during copulation
Corpora cavernosa
Spongy tissue surrounding the urethra male reproductive system
Corpus spongiosum
Species with corkscrew shaped glans penis
Porcine
Species with cornfield spine glans penis
Feline
Foreskin of penis
Prepuce
Invagination of the skin enclosing the free extremity of the retracted penis and its opening is covered by coarse hair
Prepuce
A sac dorsal to the prepuce
Preputial diverticulum
Mixture of fatty secretion, cast of epithelial cells and bacteria
Smegma
Primary sex organs of males
Testes
Housed outside the abdomen in the scrotum
Testes
Produces spermatozoa in the seminiferous tubules
Testes
Network of tubules connected to the seminiferous tubules
Rete testis
Connect the rete testis and epididymis; collectively forms the epididymal duct
Efferent ductules
“Nurse cells” provide nourishment and support to developing sperm cells
Sertoli cells
undifferentiated male germ cells
Spermatogonia
Fully differentiated male germ call
Spermatozoon
Houses the spermatozoa as they mature before they are expelled by ejaculation
Epididymis
Tube passing thru the pens to the outside of the body
Urethra
Undergoes peristaltic contractions during ejaculation
Ductus deferens (vas deferens)
Responsible for coital lock
Bulbus glandis
Amount of semen pigs produce
Approx. Half liter
Located caudal /around the bladder or cranial portion of the pelvic urethra; secretes alkaline solution; clear and lubricate the urethra during pre-coital
Prostate gland
Paired glands associated with the genital fold; source of fructose, ascorbic acid, citric acid
Vesicular glands
Removal of the testes of the male animal
Castration
Absence of both testes from the scrotum
Cryptorchidism
One testes is absent
Monorchid
Transection (ligation) of the ductus deferens (vas deferens)
Vasectomy
Site of spermatogenesis
Tail of epididymis
Produces estrogen
Granulosa cells
External genitalia of the female; comprises right and left labia
Vulva
Erectile tissue in female
Clitoris
Site of semen deposition during copulation; passageway for fetal and placental delivery
Vagina
Opening into the bladder on the floor of the vagina
Urethral orifice
Site for placental formation
Uterus
4 types of uterus
Bicornuate
Bipartate
Simplex
Duplex
Neck of the uterus
Cervix
Sphincter-like structure, serves as a muscular value that keeps the uterus sealed off from the vagina
Cervix
The muscular portion of the uterine wall; increases in size during pregnancy
Myometrium
Innermost lining of uterus
Endometrium
Mushroom-like non-glandular projections found at the inner surfaces of the uterine horn and body
Caruncle
Circular structures distributed in ruminant placenta
Cotyledon
Funnel like structure that pick up the ovulated egg
Infundibulum
Site of fertilization in female reproductive system
Ampulla
End of sexual receptivity
Metestrus
Short period of sexual activity between recurrent periods of estrus
Diestrus
Condition of a female animal while young are developing within her uterus
Pregnancy
Stage of pregnancy at which the emerge adheres to the wall of the tens
Implantation
The development of fetal membranes
Placentation
In avians, only the _____ side of the ovary develops
Left
Egg yolk =
Ovary
Site of fertilization (avians)
Infundibulum
Secretes the egg’s outer cuticle and possibly the Shell
Vagina
Shell gland =
Uterus
