Answer: The statement is TRUE.
Explanation:
The thin, yellowish milk which may appear at any time from late pregnancy to few days right after birth is known as Colostrum milk.
During pregnancy, progesterone and oestrogen cause the milk glands to develop in the mother's breast. Immediately after birth, the anterior lobe of the pituitary releases a hormone, prolactin, which stimulates milk production. When the baby suckles at the mother's nipples, the milk flows out.
This first yellowish milk known as colostrum, contains all the essential nutrients that a newly born baby needs. It also provides antibodies and immune cells that protect the infant from disease. The milk is rich in protein and fats than normal milk. It is the first immune system defense they receive after birth. Therefore the above statement about the first thin yellowish milk is TRUE.
The process is ocurring by steps, starting with depolarization.
1- Na+ permeability > K+ permeability
2- Vm (membrane potential) approaches ENa+ (quilibrium potential for potassium)
3- K+ permeability > Na+ permeability
4- Vm (membrane potential) approaches EK+ (quilibrium potential for potassium)
