Lecture 9 Menstrual Cycle and Pregnancy

Question 1

Which of the following hormones promotes
peripheral vasodilation and heat dissipation?
a) Progesterone
b) Oestrogen
c) Follicle-Stimulating Hormone (FSH)
d) Luteinising Hormone (LH)

Answer 1

b) Oestrogen

Question 2

Compared with the mid-luteal phase, the
early follicular phase of the menstrual cycle
is associated with which of the following?
a) Higher levels of estrogen and progesterone
b) An increase in core body temperature of 0.3-
0.5°C
c) Higher core temperature threshold for sweating
d) Lower resting blood pressure

Answer 2

d) Lower resting blood pressure

Question 3

When compared with non-pregnant women, exercise
during pregnancy is associated with which of the
following?
a) Reduced stroke volume across different exercise
intensities
b) Reduced heart rate across different exercise
intensities
c) Reduced arteriovenous oxygen difference (a-vO2
diff) across different exercise intensities
d) Reduced cardiac output across different exercise
intensities

Answer 3

c) Reduced arteriovenous oxygen difference (a-vO2 diff) across different Exercise intensities

Question 4

According to Jarvis et al. (2012), high muscle
sympathetic nerve activity in the first trimester of
pregnancy does not lead to elevated resting blood
pressure because:
a) vascular transduction is reduced
b) heart rate is reduced
c) cardiac output is reduced
d) blood volume is reduced

Answer 4

a) vascular transduction is reduced
