ALS 3304 Exam 2 Lecture Questions with Correct Answers Latest Update 2026/2027
Liqour Folliculi - Answers fluid which fills the follicular antrum and surrounds the ovum in an
ovarian follicle
Cornua - Answers Horn of the uterus; the structure resembling the horn
Why is placement of repro tract significant in domestic animals? - Answers The repro tract is
directly beneath the rectum
(rectogenital pouch) this placement allows for the transrectal palpation and ultrasounds in cows,
mares, and camels
Rectum palpation - Answers Pregnancy, cycle, and repro issue
List the 4 layers common to all portions of the repro tract - Answers serosa
muscalaris
submucosa
mucosa
serosa - Answers outermost, single layer of squamous cells (simply covers the surface of the
reproductive tract)
muscalaris - Answers double layer of smooth muscle and the size depends on the placement in
the repro tract (outer longitudinal and inner circular; provides ability to contract; transport of
secretory products, gametes, early embryos and expulsion of the fetus and fetal membranes)
submucosa - Answers houses blood vessels, nerves and lymphatics (blood vessels, nerves, and
lymph vessels run through this and varying thickness depending upon region; also serves as
supportive tissue for the mucosal layer)
mucosa - Answers secretory layer of epithelium and this is used when talking about vagina,
cervix, oviducts, and uterus. This also changes depending on cycle stage. (each region of tract
lined w/ different type of mucosal epithelium ex: oviduct has mixture of ciliated & non-ciliated
columnar epithelium & posterior vagina lined w/ stratified squamous epithelium)
broad ligament - Answers 1. double layered connective tissue
2. the embryonic origin -peritoneum
3. Function: suspends ovaries, oviducts, uterus, cervix, and anterior vagina
4. Function: houses vasculature, nerves, and lymphatic vessels
list the 3 portions of the broad ligament and their individual functions - Answers mesovarium
, mesosalpinx
mesometrium
mesovarium - Answers supports ovary and houses the vessels that form HILUS
mesosalpinx - Answers supports ovidcut and is a thin serous portion that also serves as bura-
like pouch
mesometrium - Answers supports uterine horns and is the largest and most conspicuous
portion
list the 4 parts of the ovary - Answers germinal epithelium
tunica albuginea
ovarian cortex
ovarian medulla
germinal epithelium - Answers not realated to germinal cells, single layer of cuboidal cells
tunica albuginea - Answers outer connective tissue
ovarian cortex - Answers usually houses oocytes and related structures
ovarian medulla - Answers central part of ovary, contains vasculature and nerves/lymphatics
where can ovulation occur at any point in the cow, eww and sow ovary? - Answers cortex, layer
on the outside
compare/contrast the equine ovary and the non equine ovary - Answers the cortex and the
medulla are flipped but they still house what they house and the mare is different in that it only
ovulates at the indentation (The mare ovary has an inversion of the cortex and medulla (outside
layer). Therefore, ovulation can only occur at theOvulation Fossa)
list the various ovarian structures - Answers follicles: primordial follicle, primary follicle,
secondary follicle, teriary follicle, graafian
Corupus Luteum
corpus hemorrhagicum
corpus albicans
Follicle - Answers contains oocyte
fluid filled
