266 VETERINARY STATE BOARD 



Uterus: place of nourishment and development of the embryo 

 and foetus. 



Vagina: eopulatory organ and passageway for the foetus dur- 

 ing parturition. 



Vulva : same as the vagina. 



Mamm.3d: supply nourishment to new-born. 



Define orgasm. 



Orgasm is the crisis of venereal excitement, that is, the time of 

 ejaculation of semen. 



State the organic modifications the genital organs undergo after labor. 



The uterus reduces in volume and weight by the oxidation, de- 

 generation and absorption of the cells of the muscular fibres. The 

 mucous membrane, which has been enormously thickened, under- 

 goes fatty degeneration and modification until the uterine interior 

 presents the appearance it possessed before impregnation. The 

 cervix contracts, closes and regains its former shape. 



Describe the difference between the maternal and the foetal cotyledons. 



The maternal cotyledons are dark-yellow in color and their 

 surface is covered with crypts. The fetal cotyledons are bright-red 

 in color and on their surface is a multitude of long, branched villi 

 which are received into the depressions of the maternal cotyledons. 



Are spermatozoa always found in the semen ? Explain. 



No. They are usually absent in cases of cryptorchidism, testicular 

 tumors, inflammations and degenerations of the testicles. Hydro- 

 cele may prevent the formation of spermatozoa. The following 

 conditions — debilitating diseases, overwork and excessive sexual use, 

 individually or jointly — lessen the abundance of the male fertilizing 

 element and in some cases may lead to a complete absence of same. 



Is the vagina strictly a generative organ? Explain. 



Yes. Because it serves as an organ of copulation and as a passage- 

 way for the foetus only. 



Give the meaning of each of the following terms: uniparous, multi- 

 parous, primiparous, pluriparous. 



Uniparous refers to animals which bring forth but one offspring 

 at birth, as the mare and cow. 



Multiparous refers to animals which bring forth several offspring 

 at one time, as the bitch and cat. 



Primiparous : Bearing, or having borne but one offspring. 



Pluriparous : Same as multiparous.
