What is the main function of the female reproductive system?
To produce ova and provide a suitable environment for fertilisation + development of embryo
What is the franework of the ovaries??
Consists of connective tissues , blood capillaries and smooth muscle
A large number of germ cells and developing follicles are contained within
Function of the Ovaries?
Produce eggs ready for fertilisation
- secrete oestrogen + progesterone
- they collect, convay ova and provide the correct environment for survival of spermtova
Ovaries are attached to the dorsal body by?
Ovarian suspensory ligament
The ovaries are supplied with blood by the?
Ovarian artery
The ova are produced within follicles that then form the?
Corpus Luteum
What dose the infundibulum do?
Funnel shaped catches and releases ova
The oviducts are lined with Cilliated epithelium that?
Move ova down to the uterus fertilisation takes place within the oviducts
What dose the uterus (uterine body and horns) do?
Y-shaped structure ova implant here for duration of pregnancy
The wall of the uterus is made up of layers of smooth muscle called MYOMETRIUM
The mucos lining of the uterus is called ???
Endometrium
Contains blood vessels
The female reproductive track is made up of what structures?
- 2 ovaries
- Fallopian tubes
- Uterus(horns n body)
- cervix
- vagina
- vestible
- clitoris
- Vulva
Entire uterus is suspended in a fold of peritoneum called?
The Mesometrium
The Myometrum is responsible for?
Uterine contractions during parturition
What is the cervix function?
Sphincter between uterus + vagina
Main function is to protect uterus to outside
Convey urine from urethra to outside also convey sperm
What dose the endometrium do?
Thickens during pregnancy to provide nutrient for foetus
Function of the testies?
- produce sperm
- secrete testosterone
- produce fluid which transport sperm
Male repo system is made up of ?
- Testies
- Epididymis
- vas deference
- prostate gland
- penis
- prepuce
What is the main function of the male repoductive track?
Production, storage and nourishment of sperm for transfer to female
As testies develope they are pulled out of abdomen by?
Ingual ring
Thro contraction of the gubernaculums
In cases where the testes do not descend properly it is called ??
Cryptorchid
Dogs born with one testicle are described as?
Monorchid
What is the spermatic cord?
Thin strip of muscle that runs within
Called the cremaster muscle raises and lowers testicles
What are the connective tissues and interstitial cells in-between seminiferous tubles knows as?
Cells of Leydig
What do spermatogenic cells do?
Produce spermatozoa by meiosis
What do Sertoli cells do?
Produce Oestrogen + nutritional fluid for sperm
What do the interstitial cells of Leydig do?
Produce testosterone
What is testosterone responsible for?
Responsible for development, maintenance or secondary sexual characteristics +
Spermatogenesis
What dose the deferent duct do?
Carries sperm from Epididymis to urethra empties thro prostate gland
What dose the prostate gland do?
Produces a large ammount of seminal fluid that make up the volume of ejaculation
Helps sperm to survive + neutralises acidity of any urine present in the urethra
The penis consists of?
- Urethra
- os penis (tunnel shaped bone)
- corpus - cavernosum penis
- corpus - sponginosum
•retractor penis muscle
What happens when the cats penis is engorged?
Rotates into cranialventral position to facilitate mating penis had backwards facing spines
What is spermatogenisis?
Process of making sperm cells or developing immature germ cells (spermatogonia)
Mature cells (spermatozoa)
Sperm is made in the certoli cells
