Question

Describe the basic sequence of developmental stages from conception to infancy. Discuss the challenges of teratogens, and describe the reflexes a newborn should have.

Answer 1

Answer:

The primary sequence of development stages consists of many stages. The first step is conception, where a child is conceived by the man and woman in a woman's stomach. You have a zygote, the fertilized egg, which then enters two weeks of rapid cell division and develops into an embryo. The embryo is the developing stage of the human organism, which lasts from about two weeks after fertilization through the second month of the pregnancy. After the embryo, the fetus is developed. It is the developing human organism from 9 weeks after conception to birth. Then the mother gives birth after nine months of conception, where the fetus enters the infancy stage of life.

There are many challenges faced during pregnancy, and one of them is teratogens. Teratogens are viruses or drugs that can damage an embryo or fetus. This is the reason a woman cannot drink alcohol during pregnancy. Teratogens are one of the main reasons that cause miscarriages or stop the development of the fetus.

Newborns have many reflexes when they are born. Some examples of these reflexes are rooting reflex, suck reflex, Moro reflex, and grasp reflex. This reflex starts when the corner of the baby's mouth is stroked or touched. Suck reflex is when the roof of the baby's mouth is touched. Moro reflex, also known as the startle reflex, is when the baby is startled by a loud sound or movement. The grasp reflex is when stroking the palm of the baby's hand, and the baby closes his or her fingers in a grasp. These are some of the reflexes a newborn baby should have.

Answer 2

Answer:

The basic sequence of development stages consist of conception(a child in conceived by the man and woman in the stomach of a woman), Zygotes(the fertilized egg, enters a 2-week period of rapid cell division and develops into an embryo), Embryo(the developing human organism from about 2 weeks after fertilization through the second month of the pregnancy), Fetus(the developing human organism from 9 weeks after conception to birth), Birth(the woman give birth 9 months after conception). Teratogens are viruses or drugs that can damage an embryo or fetus. Teratogens are a reason why woman cannot drink alcohol during pregnancy. Teratogens can cause miscarriages or stop the growth of the fetus. Newborns have many reflexes they are born with, such as the rooting reflex. The rooting reflex occurs when something touches a baby's cheek and the baby turns toward that touch, open their mouth and begin sucking on it. For example when a newborn needs to eat they root for a nipple.
