Final answer:
Quickening refers to the first perceived fetal movements by the mother and is an important milestone in pregnancy.
Step-by-step explanation:
During pregnancy, there are several expected physiological changes that occur. One of these changes is called quickening, which refers to the first perceived fetal movements by the mother. It is considered an important milestone of pregnancy and usually occurs around the 20th week. Quickening is characterized by fluttering or gentle movements in the lower abdomen, and it indicates that the fetus is growing and becoming more active.
For example, a pregnant woman may describe the sensation of quickening as similar to butterflies fluttering in the stomach or bubbles popping. It is important to note that every woman may experience quickening differently, and it can be influenced by factors such as the position of the fetus, the location of the placenta, and the mother's body size.
In conclusion, the statement in the question is true. Quickening refers to the active fetal movements felt by the mother during pregnancy.
