Developmental Biology Final Exam Study Guide 12/3/11 Part I Chapter 1 -Basic Problems of developmental Biology: • Maintenance of complete genome while cells differentiate -Main mechanisms of differential gene expression-polarity and cytoplasmic differences; polarity: • Gene expression leads to a difference in cells • Every cell in body has the same genome • Gene regulation occurs: o Polarity and cell division ▪ Uneven egg contents ▪ Environmental factors

Komal Gupta 1313232 Psychology Honours Hindbrain Outline The introduction briefly talks about the hindbrain‚ its location‚ structure and highlights its main functions. It also talks about how the hindbrain is divided. The next topic is about Structure and Function. It first starts with the functions of the hind brain and then mentions each and every function of the brainstem‚ that it‚ the medulla‚ pons and the cerebellum. It also mentions the functions of the cranial nerves. The next section is

propagate various types of viruses. Because of the ability to alter their tropism and to adapt to a new host species‚ many viruses become capable of growing in chick embryo tissues wherein they frequently attain a much higher concentration than in the tissues of the natural host. STRUCTURE OF AN EGG The extra-embryonic membranes of the chick embryo arise from three germinal layers: the endoderm‚ mesoderm and ectoderm (Fig. 1). The dorsal somatopleure consists of ectoderm on one side and mesoderm on

genetically distinct cells that originate from different zygotes involved in sexual reproduction Understand the types of injuries/assaults an early embryo can withstand and still develop normally. LOTS OF SHIT Understand what teratogens are and when they are most likely to affect an embryo. What is Thalidomide? An agent or factor that causes malformation of an embryo. Likely to affect during gastrulation. Thalidomide was a drug formally used as a sedative‚ but in the ‘60’s was found to cause congenital malformation

Vaccines Vaccinations are a big part of people’s lives. There are immunization programs for children that very much encourage vaccinations; starting them off early as steady‚ life-long customers. Years ago‚ when vaccines were first invented‚ they were made up of saline solution and the dead virus. Now‚ there’s so much more in the vaccine that most people don’t know about. The way that vaccines are made is unethical‚ from the ingredients‚ to the way the ingredients are collected. Many who get vaccinated

development is the most significant segment of human development. 15 days after conception the embryonic stage begins and continues until about the 8th week‚ or until the embryo is around an inch in length. The cells of the embryo are multiplying and taking on different functions. This critical period‚ the first trimester‚ the growing embryo is most susceptible to damage from external sources including viral infections‚ x-rays and other radiation‚ and poor nutrition. By the third week‚ the heart is forming
