(52 cards)
Oestrogen effects
Maintain body temp, breast, vagina, ovary and uterus development,
Spermatogonium
Become encased in sex cords and cease mitosis
Where does ureter drain into?
Superior and posterior bladder
Location of perineal membrane?
Beneath levator ani
When does meisosi I completed in women?
Pre-ovulatory stage with LH surge
Sympathetic fibres on genitals and sphincter
Cause smooth muscle contraction of internal male sphincter and genitals
Wollfian duct progenitors
Epididymis and vas deferens
What happens to the primary oocyte during folliculogenesis?
Arrested in meiosis I while gollicular growth occurs. Nuclear maturation occurs in meiosis I when there is an LH surge to rpoduce secondary oocyte arrested in metaphase
Receptor for GnRH
GnRH1- G protein coupled receptor
Which cells contract to move sperm out of the testes?
Myoid cells of seminiferous tubules
What surrounds the bladder in males?
Prostate
Percentage of sperm for good fertilisation
4%
Which muscle shares a tendon with the bulbospongiosus muscle?
Transverse perineal muscle
Vein down the penis shaft
Deep dorsal vein which drains into the prostate plexus
What happens to the cortex of the mesonephors in males?
Degenerates- vice versa for males
Uterine cycle
Uterine- menstruation, proliferative and sectetory phase
Menstrual cycle
Menstrual- follicular phase, ovulation and luteal phase
Cytoplasmic maturation
Mitochondria and cortical granules relocate to periphery
Precursor to all sex steroid hormones
Pregnenolone
Space between perineal membrane and pelvic diaphragm
Deep perineal pouch
Oogenesis
Mitosis begins in foetus but is arrested in meiosis I diplotene until ovarian cycle
What secretes sugar rich fluid for sperm?
Seminal veiscle
Effects of oestrogen on brain
Body temp for vasomotor changes and protect against memory loss
Orgasmic platform
Thickening of lower third of vagina when uterus is fully elevated
