Q

involved in the secretion of prolactin during pregnancy

A

estrogen

20
Q

true or false

Lactation success is dependent on breast size.

A

False

21
Q

True or False

The internal mammary and the lateral thoracic arteries provide the majority of the blood supply to the breast.

A

true

22
Q

True or False

Progesterone is the major influence on breast growth during puberty.

A

false

23
Q

True or False

Complete development of breast function occurs only in pregnancy.

A

true

24
Q

True or False

The increase in estrogen and progesterone levels following the expulsion of the placenta triggers lactogenesis.

A

false

25
Q

True or False

Suckling by the infant stimulates a decrease of prolactin.

A

False

26
Q

True or False

Milk production is dependent upon the efficient removal of milk from the breast.

A

True

27
Q

True or Flase

The anterior pituitary secretes oxytocin, which causes the letdown response

A

False

(posterior pituitary)

28
Q

True or False

Prolactin’s influence on breast tissue during pregnancy is toincrease the size of the breast.

A

true

29
Q

True or Flase

Women who have flat or inverted nipples cannot breastfeed successfully.

A

False

30
Q

What is the function of the Montgomery’s tubercles?

A

Secrete a lubricating substance for the nipple and areola

31
Q

Which of the following is not a factor involved in lactogenesis?

  • Delivery of the placenta
  • Infant suckling the breast
  • Elevated estrogen levels
  • Elevated prolactin levels
A

Elevated estrogen levels

32
Q

Lactogenesis is initiated following delivery by

A

decrease in estrogen levels and increased serum prolactin level.

33
Q

Which hormone is responsible for the milk-ejection reflex?

A

Oxytocin

34
Q

Prolactin levels are

A

higher during the night.

35
Q

Galactopoiesis is dependent upon all of the following except

  • the regulation of prolactin and oxytocin by the hypothalamus.
  • milk synthesis and milk release into the alveoli.
  • increased levels of prolactin as a result of infant suckling.
  • control by the endocrine system.
A

control by the endocrine system.

36
Q

The milk-ejection reflex is initiated by all of the following except

  • stimulation of the neural and endocrine systems.
  • tactile receptors in the areola.
  • tactile receptors for prolactin and oxytocin in the nipple.
  • sensory stimulation of the mother.
A
  • stimulation of the neural and endocrine systems.
37
Q

Milk production is most dependent upon which of the following factors?

  • Adequate maternal nutrition
  • Efficient removal of milk from the breast
  • The baby suckling at the breast
  • High serum oxytocin levels
A

Efficient removal of milk from the breast

38
Q

Which of the following does not interfere with the milk-ejection reflex?

  • Ice applied to the nipple to make it erect
  • Psychological stressors
  • Engorgement
  • Application of moist heat and breast massage
A

Application of moist heat and breast massage

39
Q
A
40

Intercostal nerve III

41
Q

What nerve enters the breast on the left side at 2 o’clock?

A

Intercostal nerve IV

42
Q

What nerve innervates the nipple?
