Q

What is the ovary histology?

A
  • Simple cuboidal germinal epithelium
  • Tunica albuginea (connective tissue capsule- same name as capsule around testis)
  • Stromal connective tissue
  • Follicles in cortex= oocytes & supporting cells
  • Roughly 400 (oocytes) fully released in lifetime

Q

Why are there roughly 400 oocytes released in lifetime?

A

Birth roughly 2 million follicles- mitosis during foetal life, then paused in meiosis. When puberty a new surge of hormones begins oogenesis
Puberty roughly 400,000 follicles

Q

What happens during ovulation?

A

One will be released the rest will go through Atresia. More follicles recruited to go through oogenesis than will complete cycle so will degenerate.

Q

What happens to CL during pregnancy?

A

CL enlarges and remains throught pregnancy

Continues to produce progesterone and estrogen, stop uterine wall from shedding (preventing miscarriage)

Q

How does high insulin and T alters follicle development in Polycistic (PCOS)?

A
High insulin & T alters follicle dev
Many follicles develop but not fully
No ovulation
Difficulty conceiving
Weight gain and hirsutism- increased testosterone

A

Receives oocytes

Pathway to uterus

29
Q

What is fallopian tubes lined by?

A

• Lined by mucosa- mucous membrane
o Simple columnar epithelium
o Cilia to help move egg

30

A

Roughly 6-10 days

32
Q

What happens in an ectopic pregnancy?

A

Egg implants outside the uterus

33
Q

45
Q

What do cervica mucosa glands do?

A

Mucus barrier to substance from the vagina

Near ovulation, consistency of mucus changes

46
Q

What can identify cervical cancer?

A

Abnormal changes in cell shape

47
Q

What happens during early cervical cancer?
