Angiopromoters - vessel promoting factors

Antrum - space that contains follicular fluid

​

C

cervix - "gatekeeper" to the uterus

Corpus albicans - regressed CL, becomes scar tissue, has no function

corpus hemorrhagicum - blood that fills follicle after ovulation

Cryptorchid - failure of testes to descend in mature male

​

G

gamete - sex cell (sperm or egg)

gonadectomy - removal of gonads (female ovaries, male testes)

​

H

hilus - point of attachment between ovary and body

hydrosalpinx - free fluid in oviduct due to broken oviduct (these animals will ovulate and show heat but never get pregnant)

hysterectomy - removal of uterus (hyster), leave ovaries

​

I

Impotence - inabiity to copulate successfully

​

L

lordosis response - cats "stand" in response to back pressure

orchidectomy - removal of testes

ovariectomy - removal of one or both ovaries

ovariohysterectomy - classic spey: removal of both the ovaries and uterus

​

P

polycystic ovarian disease/syndrome - cystic ovaries are large, excess of large follicles, can get up to the size of a basketball

prostatectomy - removal of prostate gland

puberty - when first gamete is put into the duct system. Sperm --> lumen of seminiferous tubule, egg --> oviduct

Pyometra (closed) - infection of uterus, cervix is closed and everything is retained in uterus

Pyometra (open) - infection of uterus, cervix is open and pus comes out of vulva

​

S

salpingectomy - removal of fallopian tubes (oviduct)

segmental cornual aplasia - absence of tube into one side of the uterus, fluid collects in horn

​

U

unilateral compensatory hypertrophy - compensatory growth of organ when its match is removed

​

V

vasectomy - cutting of vas deferens to prevent function
