Organes geniteaux Feminins: 1

Question 1

Explain the Développement du col utérin

Answer 1

Avant la puberté : épithélium glandulaire limité à l’endocol (portion tubulaire qui n’est pas directement en contact avec l’environnement vaginal

Lors de la puberté : hyperplasie de l’épithélium glandulaire de l’endocol –> glandes dans l’exocol -> l’épithélium glandulaire est en contact avec l’environnement vaginal (portion appelée ectropion)

Because the epithelium is not adapted for the low vaginal pH -> Métaplasie graduelle pour rétablir une muqueuse squameuse en remplaçant l’épithélium glandulaire

THIS IS zone de transition

Zone de transformation is more a concept (it happened)

Question 2

Zone in contant danger of infenctions in the female genital system

Answer 2

zone de transition

Question 3

During the mentrual cycle, the main hcanges occur in the?

Answer 3

Endometre has changes in the glands and in it’s stroma

Not any changes really in the myometre this is the layer imporatnt for giving birth so that’s really the only time

Question 3

Describe the phase prolifere of the menstrual cycle?

Answer 3

Phase proliférative :
lots of mitosis
* Prolifération des glandes et du stroma endométrial
* Glandes de petites taille, no secretion

Question 4

Describe the phase sécrétoire of the menstrual cycle?

Answer 4

Précoce: aspect tortueux, vacuoles sous-nucléaires

Intermédiaire: sécrétions importantes The stroma has space between nuclei because lots of mucous between cells

Tardive : pseudo-décidualisation du stroma. The stroma has space between nuclei but that is because the cells now have a large cytoplasm

Question 4

What is Analyse cytologique?

Answer 4

Test Pap
consiste à observer au microscope un prélèvement du col utérin afin de dépister un cancer ou des lésions pouvant évoluer vers un cancer du col utérin.

• Cellules individuelles ou en petits amas
• Pas d’inclusion dans un bloc de paraffine, et pas de coupe au
  microtome
• Les cellules entières sont apposées sur la lame, et les cellules et les
  amas ont tendance à s’aplatir sur la lame
• Cellules vues en face

Question 5

An oocyte sorrounded by squmous cells is likely to be?

Answer 5

Follicules primordiaux

epithelium= follicular cells

Question 6

Follicules primaires vs Follicules primordiaux?

Answer 6

• Follicules primaires have cuboïdales follicular cells

Question 7

What signifief that we have reached secondary follicle?

Answer 7

The presence of the antrum (antre)- zone de liquide
But also we see:
Zona pellucida around the oocyte
zona granulosa (important for hormones eventually)
theca interna (important for hormones eventually)

Question 8

What is the etape terminale of the secondary follicle?

Answer 8

Creation of follicules de Graaf

Question 9

What is corps jaune?

Answer 9

corpus luteum (or corps jaune) is like a tiny factory that forms in the ovary after an egg is released. Its job is to produce a hormone called progesterone. If the egg is fertilized (meaning you’re pregnant), the corpus luteum keeps working. If not, it shuts down, and your period starts. It’s a key part of the menstrual cycle and early pregnancy

same structure as secondary follicle

Question 10

What is corps blanc?

Answer 10

the corpus albicans is like a small scar that forms in the ovary after an egg has been released and not fertilized. It’s part of the natural cycle of changes that occur in the ovaries.

fibrose laissée par des follicules épuisés

Question 11

Cellules myoépithéliales vs Cellules luminales in function and where we find them?

Answer 11

Find them in the mammary gland
Cellules myoépithéliales (couche basale)
Cellules luminales (role de sécrétion; centrales dans les acini)
