reproductive
Where is the site of fertilization
ampulla
What is the time required to reduce blood concentration of a hormone by 50%
half life
How many cm should the cervix be dilated to
10 cm
What is the process of hormones regulating the receptor levels of other hormones called?
permissiveness; for example, thyroxine can increase the receptors of adrenaline to increase heart rate, stroke volume etc
what part of the uterus is shed during menses
functional layer
Which disease is caused by a problem on the thyroid stimulating hormone receptor?
Grave's disease
This hormone shifts fuel towards mother in period of illness
prolactin
The release of this hormone from the posterior pituitary gland affects blood pressure
vasopressin
Which hormone dominates during the luteal phase
progesterone
What is the effect of cAMP in the GPCRs?
it activates protein kinase A
What is the chimeric organ consisting of uterine and embryonic tissue
placenta (2 sets of DNA)
This hormone of the adrenal gland promotes immunosupression, increased protein degradation, increased lipolysis
glucocorticoids (cortisol)
Which duct of early development is associated with females
Mullerian duct (oviduct)
Give at least 2 effects of thyroxine in the body
increased lung ventilation in the lung, increased basal metabolic rate, increased heart rate, increased protein catabolism, increased lipolysis
This condition happens when the placenta implants in the inferior uterus, covering the internal os of the cervix
placenta previa
This hormone is used by the embryo to signal to the corpus luteum that implantation has happened
Human chorionic gonadotropin (hCG)
Which cells help develop tight junctions that form blood testes barrier?
Sertoli cell
This hormone/neurotransmitter inhibits prolactin
dopamine
What mechanisms prevent polyspermy?
The cortical granules migrate towards the oocyte plasma membrane after the first sperm fusion and form a new barrier in the PVS
What part of the ovum insures that only human males can impregnate human females? and what part of the sperm breaks that barrier?
Zona pellucida and acrosomal cap
