67
Q

PREGNANCY PHYSIOLOGY
In pregnancy, what changes to the humoral and cell-mediated immunity?

A
  • Humoral = unchanged, plenty of circulating Th2 cells to fight infections (antibodies)
  • Cell-mediated = reduced as progesterone down regulates production of Th1 cells (phagocytes, cytotoxic T lymphocytes)
68
Q

REPRODUCTION
What are the different stages in follicular genesis and what stage in the cell cycle are they?

A
  • Primordial follicles = diploid, arrested at prophase I
  • Primary follicle = diploid, undergoing meiosis I
  • Secondary follicle = haploid, once meiosis I complete
  • Antral (Graafian) follicle = haploid, frozen in metaphase II
69
Q

REPRODUCTION
What happens immediately after fertilisation?

A
  • Cell rapidly divides > mass of cells (morula) travels to uterus
  • Fluid filled cavity (blastocele) expands to form blastocyst (>80 cells) with outer layer (trophoblast) + inner layer (embryoblast)
70
Q

REPRODUCTION
What are the main hormones produced by the placenta?

A
  • hCG (maintain corpus luteum)
  • Oestrogen
  • Progesterone
  • Human placenta lactogen
71
Q

REPRODUCTION
What is the role of oestrogen in pregnancy?

A
  • Softening tissue > more flexible, allows muscles + ligaments of uterus and pelvis to expand + cervix become soft
  • Enlarges + prepares breasts + nipples for breast feeding
  • E3 declines with foetal distress, E2 increases endometrial progesterone receptors
72
Q

REPRODUCTION
What is the role of progesterone in pregnancy?

A
  • Produced by corpus luteum until 10w
  • Initially prepares endometrium for implantation by proliferation, vascularisation + decidual reaction
  • Later, maintains pregnancy by preventing contraction
  • Relaxation elsewhere > heartburn, constipation, hypotension
73
Q

MENSTRUAL CYCLE
what happens during the follicular phase?

A
  • rising levels of FSH stimulates developing follicles to produce oestrogen
  • oestrogen inhibits FSH leading to one dominant follicle
  • follicle starts developing LH receptors
  • egg completes first meiotic division
  • oestrogen levels cause positive feedback leading to LH surge
74
Q

MENSTRUAL CYCLE
What happens in the early secretory phase of the menstrual cycle?

A
  • after ovulation progesterone predominates
  • changes from focusing on growth to preparing for implantation
  • development of complex glands, increased spiral arterioles
  • endometrial cells produce and store glycogen
75
Q

MENSTRUAL CYCLE
What happens in the late secretory phase of the menstrual cycle?

A
  • Cervical mucus thickens + less hospitable for sperm
  • Decrease in oestrogen + progesterone > spiral arteries collapse + constrict + functional layer prepares to shred
76
Q

MENSTRUAL CYCLE
What are the stages of the menstrual cycle?

A
  • Menstruation (Days 1-5)
  • Proliferation (Days 6-14)
  • Ovulation (Day 14)
  • Secretion (Days 16-28)
77
Q

MENSTRUAL CYCLE
What happens in the proliferative phase?

A
  • endometrium grows under influence of oestrogen

  • early development of glands and spiral arterioles
78
Q

MENSTRUAL CYCLE
what are the stages of the ovarian cycle?

A

follicular phase
luteal phase

79
Q

MENSTRUAL CYCLE
what happens during the luteal phase?

A
  • follicle becomes corpus luteum (lifespan of 14 days)
  • corpus luteum secretes progesterone which peaks 7 days after ovulation unless maintained by pregnancy
  • falling progesterone causes menstrual bleeding
80
Q

MENSTRUAL CYCLE
What happens during the menstrual phase?

A
  • falling levels of progesterone cause shedding of endometrium
  • spasm of spiral arteries
  • ischaemic necrosis
  • generalised inflammation
