What are the 5 major components of the female reproductive tract? |

|
What are the 4 Concentric layers of the female reproductive tract? |
1. Serosa 2. Muscularis 3. Submucosa 4. Mucosa |
|
Describe the Serosa the first concentric layer. |
is the outer most coating made up of squamous cells |
|
Describe the Muscularis the second concentric layer. |
is a double layer of smooth muscle. this smooth muscle layer is also referred to as the myometriom ( gives the tract the ability to contract and relax |
|
Describe the Submucosa the third concentric layer. |
houses blood vessels, nerves and lymphatics |
|
Describe the Mucosa the forth concentric layer. |
is the seconed layer of the epithelium. and secretes materials into the lumen of the uterus to enhance embryo development and sperm viability |
|
What is the Myometrium (or Musculares)? |
a double layer of smooth muscle. this smooth muscle layer is also referred to as the myometriom ( gives the tract the ability to contract and relax |
|
What is the endometrium? |
the submucosa and mucosa of the uterus comprise the endometrium. |
|
What is the function of the broad ligament? |
The broad ligament supports the female reproductive tract and houses the vascular supply, lymphatic drainage and nerves for the reproductive organs. |
|
Describe the anatomy of the ovary. |
There are 2 parts to the ovary. The Mudula which is the inner part of the ovary and the cortex which is the outer part of the ovary. |
|
How is the mare's ovary different from other domestic species? |
The mare's ovary is inside out compared to other domestic species. The Mudula is the outer part of the ovary and the Cortex is the inner part of the ovary. |
|
What are the 4 types of follicles? |
1. Primordial Follicles 2. Primary Follicles 3. Secondary Follicles 4. Antral Follicle (aka Tertiory Follicle) |
|
Describe the Primordial Follicle. |
Smallest with single layer of squomous cells |
|
Describe the Primary Follicle. |
Has a single layer of cuboidal cells |
|
Describe the Secondary Follicle. |
Has 2+ layers of cuboidal cells, beginning to form fluid-filled antrum |
|
Describe the Anteral Follicle (aka Tertiory Follicle) |
is fluid-filled antrum comprises > 50% of volume and produces E2 and Inhibian. Becomes the ova |
|
How is estrodiol produced? what hormone cells are involved? |
E2 is produced by the Antral Follicle (domonate folical) 20% of the estrus cycle. produced by the granulosa cells which tern testosterone into estrodiol (E2) |
|
What are the different types of uteri ? (what species have each type)? there are 3 |
1. Duplex 2. Bicornuate 3. Simplex |
|
How does the endometrail surface vary between species? |
in ruminants the surface of the endometrium has caruncles. (protruding discs) in sows and mares the surface of the endometrium has folds |
|
Describe the Duplex uterus. |
Has 2 cervical canal that separate each uterine horn into distinct compartments (Rabbit, Marsupials) |
|
Describe the Bicornuate uterus. |
has 2 uterine horns and a small uterine body (cow, Mare, Sow) |
|
Describe the Simplex uterus. |
Has a large single uterine body with small rudimentary uterine horns (primate) |
|
How many Sperm per day does a mail reproductive system produce? |
25 billion |
|
what are the main 2 hormones produced by the mail reproductive system? |
1. Testosterone 2. Estrodiol |
|
What are the 2 primary functions of the mail reproductive system? |
1. formation of sperm 2. despoliation of sperm into the female reproductive tract |
|
The Testes are... |
the primary paired reproduction organs. |
|
What are the 2 things the Testes produce? |
1. Sperm 2. Testosterone |
|
Where is sperm produced? |
Siminiferous tubules |
|
The Siminiferous produce what? |
Sperm |
|
The siminiferous tubules must have ____________ in order to produce sperm. |
Testosterone |
|
What is the epididymis responsible for? |
Transport,concentration, storage and maturation of sperm |
|
Epididymal transport is facilitated by... |
1. Sperm production 2. peristaltic contractions and negative pressure in the vas-deferance and urethra 3. Ejaculation |
|
What is the primary storage site for sperm? |
Epididymal Tail (couda) |
|
What are the optimal conditions for sperm storage? There are 5. |
1. Low PH 2. High Viscosity 3. High CO2 4. Testosterone 5. Low metabolic rate |
|
How long can sperm survive in the tail of the epidimis? |
up to 60 days |
|
The Vasa Deferentia is part of the ____________. |
Spermatic cord |
|
What does the Spermatic cord do? |
1. Suspends the testes in the scrotem 2. Houses the Blood supply, Lymph and Nervous tissue 3. Helps with heat exchange |
|
What is the Crenaster muscle? |
The primary muscle supporting the testes (contracts and relaxes for heat exchange) |
|
What is the Pompiniform Plexus? |
Complex vasculauture created by the entuinenent of the testicular ortery and vern (important for temp controle and hormone diffusion) |
|
What is the Scrotum? |
is a two- lobed sack which encloses the testes and regulates temp |
