Exam 1 - Lecture 5 Flashcards
Types of Epithelium
* Epithelia can be classified
by:
* Shape
* _______
* _______
* _______
* Structure
* ______
* ________
* _________
squamous
cuboidal
columnar
simple
stratified
transitional
Tight junctions: create —-, prevents leakage across the epithelial layer. Eliminates —- between cells. (different from gap junctions)
barrier
space
Structural Classification: Most agricultural species have
some form of —–
Uterine —- of variable size
Uterine — is small or absent
—– cervical opening
Variation creates ___________ ________
bicornuate uteri
horn
body
single
management constraint
Uteri with short (mare) to moderate
length (cow) uterine horns.
Bipartite
Meant to distinguish between uteri
like the Horse and Pig
Bicornuate vs Bipartite (important)
Simple uterus: —- uterine body, —- uterine horns, (primates)
Duplex uterus: —- cervical openings, (marsupials and rhodents)
Large
no uterine horn
two
Anatomical Support: the 3 broad ligament.
Mesovarium: supports —-
Mesosalpinx: supports —-
Mesometrium: supports—-
ovary
uterine tube
uterus
Broad ligament is separated from the rectum by the —- —-
rectogenital pouch
Advantageous location of being proximal to the rectum
AI
Pregnancy check
Ultrasound
ovary structure: Tunica Albuginea is the —- —-. Cortex is the —- region, medulla is —- structure
outer shell
active region
support
The Ovary general structure: -
- What is germinal epithelium
Tunica Albuginea
- Tunica = —-
- Albuginea = —–
General epithelium where cells are formed
Coat
White sheet
Organizational differences: Horses have an ovulation —- (depression)
Fossa
The Ovary Two Primary Functions:
- Female —-. Houses the developing —-
—– gland
gametogensis
oocytes
Endocrine gland
What are the endocrine glands (6)
estrogen (main)
progesterone (main)
relaxin
inhibin
oxytocin
activin
The follicle development
- Primordial = 1 layer of __________
- Primary = 1 layer of ___________
- Secondary = 1 or______ layer of cuboidal
- Antral = presence of ________
squamous
cuboidal
more
antrum
The follicle development what do each cell develope?
water and estradiol
Explain antral cell in regards to LH
Big fluid filled sack, during ovulation LH would cause to shrink causing the fluid in the antrum to burst and release oocyte
Birds only have one ovary fully developed
true
What gives the ovary its orange color
lipids
Ovary luteal structures: three types of post ovulation structures:
- corpus —- (bleeding body)
- corpus —- (yellow body)
- corpus —- (white body)
Hemorragicum
Luteum
Albicans
KNOW THE STRUCUTRE OF THE AVIAN FOLLICLE
KK
Infundibulum:
responsible for —- the ovum following ovulation. Infundibulum must _______ the ovum or it will result in an ectopic pregnancy in birds.
catching
catch
What are the two subsection of the oviducts
Ampulla
Isthmus
Oviduct: —- transports the ovum, while —- transports sperm then embryo (brings sperm and egg together). Junction between these two is the site of —-.
ampulla
isthmus
site of fertilization
Where does the oviduct terminates
Utero-Tubular Junction
——– has a —- internal structure, with lots of —- —-. Muscular contractions move the —- up
Ampulla
Complex
surface area
sperm
The ___________
* Structure and function is
dictated by ___________
uterus
hormonal state
Histotroph: secreted by glands in the —-, known as “—- —-.” Helps keep —- alive by providing protein + nutrition
uterus
Happy juice
sperm
Endometrial surface: ruminants have —-, which are highly vascularized and non glandular. They develop into the maternal part of the —-
Associated with different forms of _________
caruncles
placenta
placentation
What do non ruminants have
endometrial folds
What is high vascularized
lots blood vesciles
What is non gladular
maternal contribution to placenta
Cervix:
A ___________with Periodic
permissibility
* Different types of Mucus
* _____________
* ___________-Glue
* ____________-Lubricant
Sperm transport
Pregnancy glue
Partuition
Sialomucin
Sperm transport
Estrous vs Estrus
Estrous = cycle
Estrus = heat
Cervical Structure: cervix varies between —-
Structure of the — have evolved to match the structures of the —–
Species
penis
vagina
Cervical Structure Capacitation: An —- is a cap on sperm head made of inactive enzymes. enzymes in the —- of females can —-the enzymes so the sperm can fertilize
acrosome
cervix
activate
Vagina: supports —-. Has 2 parts: —- from the —- ducts, and —- from —- sinus
microfloura
cranial from the paramesonephric duct
caudal from urogentical sinus
External Genitalia
* Structurally similar across most species
* Two sets of _____________-
* Act as an outer _________
to the female reproductive
tract
labia
barrier
Understand Reproduction in the Hen
KK
The mucosa in birds consists of —- and non ciliated secretory cells epithelial cells. Cilia actively beat in an —- direction
ciliiated
abovarian
In birds: surface epithelium and sub epithelial tubular glands source of —- in the magnum
albumen
In birds, an ovum at ovulation is surrounded by the —- layer. The IPL i composed of connective tissue fibers. Sperm must digest a hole in the over the ______ to fertilize
innerperivtielline
GD
called the germ; if
fertilized, blastoderm. Contains cell organelles and female pronucleus
Germinal disc
In birds: sperm transferred to the vagina are transported to the —-. Sperm must hide in the sperm storage tubules located in the UVJ, or the —- will spit the sperm out
UVJ
egg
