|
Antral Follicles produce?
|
Estradiol (E2)
|
|
|
The Antral follicle is made up of three layers, what are they?
|
Theca Externa (FSH binds to)
Theca Interna ( LH receptors) Granulosa Cells (FSH receptors) |
|
|
What are the functions of the Uterus?
|
- Transport sperm
- Luteolysis and control cyclicity - Environment for embryo - Maternal contribution of placenta - Expulsion of the fetus and the placenta |
|
|
What are the key vaginal componets
|
- Fornix vaginae
- Cranial vagina - Caudal vagina - Vestibule |
|
|
Fornix Vaginae
|
a crypt formed by the protrusion of the cervix into the vagina.
Composed of columnar epithelium with high secretory activity. |
|
|
Cranial Vagina
|
composed of columnar epithelium with high secretory activity
|
|
|
Caudal Vagina
|
Composed of stratified squamous epithelium secretory activity changes with endocrine status.
|
|
|
Vestibule
|
shared by both urinary and reproductive systems, extends from the urethral opening to labia
|
|
|
The clitoris is the female homologue of the?
|
Penis
|
|
|
* What are the 5 Major components of the female reproductive tract?
|
-Ovaries
-Oviducts -Uterus -Cervix - Vagina |
|
|
* Describe the 4 concentric layers of the female reproductive tract?
|
-Serosa
-Muscularias -Submucosa - Mucosa |
|
|
*What is the difference between the Endometrium and Myometrium?
|
Endometrium is made up of the mucosa and submucosa layers
Myometrium is made up of the outer longitudinal middle layer and the inner circular middle layer |
|
|
* What is the primary function of the broad ligament?
|
supports and suspends the:
Ovaries oviduct uterus cervix anterior vagina |
|
|
* What are four types of follicles?
|
Primordial
Primary Secondary Antral |
|
|
*What are the types of Uteri?
|
Duplex (rabbit and marsupials)
Simplex (primates) Bicornuate (cow, mare, sow, sheep and goats) |
|
|
*How does the endometrial surface vary between species?
|
In Ruminants the surface has caruncles which are small, non glandular areas that protrude from the surface.
Sow and Mare have no caruncles, instead they have endometrial folds which will provide the uterine surface for placental attachment |
|
|
What does the male system produce?
|
Spermatozoa
Hormones (testosterone and estradiol) Proteins and fluids |
|
|
What are the two primary functions of the male reproductive functions?
|
1. Formation of sperm
2. Deposition of sperm into the female reproductive tract |
|
|
What are the major components of the males reproductive tract?
|
- Testis
-Epididymis -scrotum - Excurrent duct system -Accessory vessels - prepuce/sheath -penis and muscles for protrusion |
|
|
Testes produce what two things
|
Sperm and testosterone
|
|
|
What hormones are secreted from the testes?
|
inhibin
estrogen |
|
|
Bilateral cryptorchid
|
sterile
|
|
|
Unilateral cryptorchid
|
Fertile
|
|
|
What is the functional layer of the testes?
|
the seminiferous tubules
|
|
|
Seminiferous tubules contain?
|
Sertoli cells (nurse cells)
|
|
|
Seminiferous tubules are the site of?
|
sperm production
|
|
|
Rete Testis
|
a network of tubules which receices sperm form the seminiferous tubules and transports it out of the testis
|
|
|
Vasa Efferentia
|
12-15 small ducts which receive sperm form the rete testis and converge into the head of the epididymis
|
|
|
What is the Epididymis responsible for?
|
- transport
-concentration -storage -maturation -rhythmic contraction of smooth muscle |
|
|
What are the three regions the epididymus is separated into?
|
-head (caput)
- Body (Corpus) - Tail (cauda) |
|
|
What contractions happen in order for ejaculation to happen?
|
Peristaltic contractions and negative pressure in the vas deferens and Uretha
|
|
|
In the epididymal storage what is the primary site for sperm storage?
|
Tail (cauda)
|
|
|
What are the optimal conditions for spermatozoa storage?
|
-low ph
-high biscosity -high carbon dioxide -testosterone -lowered metabolic rates |
|
|
Sperm entering the head are?
|
non fertile
|
|
|
Sperm entering the tail are?
|
fertile
|
|
|
what is the only purpose of the Vasa deferentia?
|
transporting sperm to the urethra for expulsion during ejaculation
|
|
|
What is the purpose of the spermatic cord?
|
suspends the testes in the scrotum
provides a pathway for blood and nervous tissue acts as a heat exchanger |
|
|
Cremaster muscle
|
primary muscle supporting the testes
Contraction and relaxation |
