A

Develop inside abdomen
Gubernaculum Runs from its caudal pole to scrotal sac, which pulls the testis through the inguinal canal and reaches scrotum by early
neonatal life

Its attaches to the ischial arch

21
Q

Sertoli cells provide support and nourishment of the
spermatozoa which are stimulated by

A

FSH Follicle Stimulating Hormone

22
Q

The Female Reproductive System structures (6)

A
  • Two ovaries
  • The fallopian tubes (oviducts)
  • The uterus – horns, body and cervix
  • The vagina
  • The vestibule
  • The vulva
23
Q

Multiparous

A

(producing more than one young at birth

24
Q

Bicornuate

A

(heart shaped)

25
Blood supply to female reproductive tract
Ovarian artery Uterine artery
26
hormones affecting the ovaries
oestrogen and progesterone
27
The Ovary is made up of
Connective tissue Smooth muscle Blood capillaries Germ cells and developing follicles
28
What bodily wall are ovaries mainly attached to
Abdominal wall
29
the ligaments of the ovaries
Suspensory Ligament Round ligament Broad Ligament
30
Suspensory Ligament attached to..?
ovary to abdominal wall
31
Round ligament attached to..?
ovary to inguinal wall
32
Broad ligament
Attached to the uterine tube (oviduct) and is continuous with the visceral peritoneum
33
Structures of the medulla in the ovary
contains blood vessels, nerves, lymphatics, muscle and connective tissue
34
Structures of the cortex in the ovary
a connective tissue ‘stroma’ which contains large numbers of germ cells
35
Mesovarium
The ovary and its nearby uterine tube are enclosed in a section of visceral peritoneum
36
The Uterine Tube AKA
(Oviduct or Fallopian tube)
37
Oviduct or Fallopian tube is lined with
ciliated columnar epithelium
38
mesosalpinx
peritoneum of the oviduct
39
Infundibulum
Open end of the oviduct has modified finger-like processes that ‘catch’ the ova
40
Fimbriae
The finger-like projections at the open end of infundibulum
41
The wall of the uterus has three layers
Perimetrium: outer serosal layer Myometrium: smooth muscle (contractions) Endometrium: lining of uterus
42
Primigravida
is an animal which is pregnant for the first time
43
Multigravida
An animal who has had several pregnancies
44
Cervix
Muscular sphincter Connects uterine body with the vagina
45
Mucoid plug
blocks cervix when pregnant to protect from infection
46
The Vagina, Vestibule and Vulva are lined with
stratifies squamus epithelium
47
Graafian follicle
A developed and ripened ovarian follicle (ovum)
48
Once the follicle has released the ovum, the follicle remnants change structure
Firstly into Corpus luteum then into Corpus albicans which resembles scar tissue and secrete hormones
49
Milk produced in response to three hormones
* Progesterone * Prolactin * Oxytocin
