Which factors would change during pregnancy if the hormone progesterone were withdrawn or reduced?
Insulin resistance would be increased.
Sweat and sebaceous glands would increase production.
Pyrosis would increase in frequency.
Peristalsis and uterine contractility would increase.
The Correct Answer is D
Peristalsis and uterine contractility would increase.
This is because progesterone is a hormone that relaxes the smooth muscles of the uterus and the gastrointestinal tract during pregnancy.
If progesterone were reduced or withdrawn, the uterus would contract more and peristalsis would increase, leading to possible preterm labor and digestive problems.
Choice A is wrong because insulin resistance would be decreased, not increased, by lower progesterone levels.
Progesterone increases insulin resistance during pregnancy to ensure adequate glucose supply for the fetus.
Choice B is wrong because sweat and sebaceous glands would decrease production, not increase, by lower progesterone levels.
Progesterone stimulates the activity of these glands during pregnancy to regulate body temperature and protect the skin from infections.
Choice C is wrong because pyrosis (heartburn) would decrease in frequency, not increase, by lower progesterone levels.
Progesterone relaxes the lower esophageal sphincter during pregnancy, allowing gastric acid to reflux into the esophagus and cause pyrosis.

Correct Answer is A
Explanation
The correct answer is choice A. Increased joint laxity contributes to increased spinal curvature in pregnant women.
Joint laxity is caused by the hormone relaxin, which loosens the ligaments and joints of the pelvis and spine to prepare for childbirth.
This can result in increased lordosis (inward curvature) of the lumbar spine and increased kyphosis (outward curvature) of the thoracic spine.
Choice B is wrong because increased weight gain does not directly affect spinal curvature, but it can cause postural changes such as anterior pelvic tilt and forward trunk lean.
Choice C is wrong because increased muscle strain is a consequence, not a cause, of spinal curvature changes.
Muscle strain can occur due to the altered biomechanics and balance of the spine and pelvis during pregnancy.
Choice D is wrong because decreased muscle strength is also a consequence, not a cause, of spinal curvature changes.
Muscle strength can decrease due to reduced physical activity, hormonal changes, or pain during pregnancy.
Normal ranges for spinal curvature vary depending on age, sex, and measurement method, but generally they are:
Sacral inclination: 30-50 degrees
Lumbar curvature: 20-45 degrees
Thoracic curvature: 20-40 degrees
Cervical curvature: 20-35 degrees
