Question

Discussion Module 3: Prenatal Development and Birth. the chapters required for the Assignment  is chapter 3 in the text book which is Lifespan development 7E. upper saddle text book.

1.Choose one piece of research from the chapters on Prenatal Development and Birth that interests you. In the title of your discussion, include the topic (from the heading in the textbook) and the page number where you found the section. For example, your title might be: How Teratogens Influence Development, pp. 64-66.

2.Add a heading in bold: Citation. Below the heading BEGIN your discussion by citing the RESEARCH—not your textbook (find the research in the References section in the back of the textbook and copy the citation into your discussion). For example:

Moore, K. L., & Persaud, T. V. N. (1993). The developing human: Clinically oriented embryology (5th ed.). Philadelphia: Saunders.

3.Add a heading in bold: Explanation of the Concept. Below the heading, write a paragraph, briefly EXPLAINING the concept in your own words (about 25 words in at least 3 sentences).

4.Add a heading in bold: Example. Below the heading, write a separate paragraph giving at least one specific EXAMPLE (tell a story) about the concept (at least 75 words). Your example might be from real life (yours of someone you know) or from a movie, book, or TV show. The goal is for you to apply the concepts in the chapter to a real-life situation.

Answer 1

EMBRYONIC DEVELOPMENT-

the first two weeks after pregnancy are the germinal stage whereby the sperm and egg unite and fertilization happens. after this stage the third to eigth week is the embryonic period.the mass of cells is now known as the embryo. it is crucial for the development of the brain. the embryo divides into 3 parts. each part forms body part. the formation of the neural tube happens after 22 days of the conception. it dewvelops into the central nervous system including the brain and the spinal cord. in the beginning two ridges form on the two sides of the neural place. gradually mre ridges form resulting in the formation of a hollow tube. after this formation of cells occur which leads to the close of tube and formation of the brain vesicles.these will develope into forebrain, hindbrain and mid brain.then from the forth week the head begins to form followed by the ear, eyes,nose etc. during the fifth week the starting buds of the arms and legs appear. also the arliest activity of heart pumping can also be seen. by the eighth week the embryo weighs 1 gram and is 1 inch lonbg and has all the parts except sexual parts. research has shown by the end of this period the development is mostly complete.
