Final answer:
The fundus is the top section of the uterus, which during pregnancy, becomes palpable as it rises with the growth of the fetus. By 18-22 weeks, the fundus is typically felt at or near the level of the mother's umbilicus, which helps in assessing the progression of pregnancy.
Step-by-step explanation:
The question 'Where is the funds palpable at 18-22 weeks?' is likely inquiring about the position of the fundus, the top of the uterus, during a certain stage of pregnancy. The fundus can be felt rising above the pelvic brim at around 12 weeks and reaches the level of the umbilicus at about 20 weeks. This knowledge is used by healthcare professionals to assess fetal growth and the progress of the pregnancy.
During approximately weeks 16-20 of pregnancy, the fetus undergoes significant development. Limb movements become stronger, and fetal movements, known as quickening, may be felt by the mother. The skin is protected by a waxy substance called vernix caseosa, and a fine hair known as lanugo covers the fetus. These changes, along with other developmental milestones, such as the beginning of controlled movements and the functioning of certain organs, like the liver producing bile, are indicative of the continuous growth and maturation of the fetus in preparation for birth
