41
Similar to dogs’ ovary but about 1 cm in diameter and ovarian bursa contains no fat
Queen
42
The site of fertilization
Oviduct
43
3 parts of oviduct:
1. Infundibulum (funnel-shaped) 2. Ampulla (bottle-neck) 3. Isthmus (narrow)
44
These are finger-like structures in the opening of the infundibulum
Fimbriae
45
The opening of the infundibulum
Ostium
46
The approximate site of fertilization in the oviduct
Ampullary isthmic junction (AIJ)
47
This site kinks to prevent premature movement of embryo, also acts as a sperm reservoir
Utero-tubal junction (UTJ)
48
Their oviduct is 8-12 inches long; tortuous, wiry, and hard (nearly cartilaginous when rolled between fingers), may also be embedded in fat (mesosalpinx)
Mare / Cow
49
Their oviduct is 6-12 inches long; UTJ serves as major barrier to sperm transport (prevent polyspermy)
Sow
50
Their oviduct is 2 - 3 1/2 inches long; slightly tortuous course around nearly the entire circumference of ovarian bursa
Bitch and Queen
51
A muscular-membrane structure and functions as: reception of fertilized ovum, fetal nutrition and protection, and initial stage of expulsion of fetus (parturition)
Uterus
52
Domestic animals often have this type of uterus
Bicornuate-shaped uterus
53
What does the uterus consists of?
2 uterine horns, a body and a cervix
54
Their endometrium consists of small protuberances called (?); intercornual ligament is present between the horns
Caruncles Cow, Ewe, Doe
55
Uterus located on the pelvic floor indicates ?
