What did you find the more complex part of the process? 2: Describe one of the cadaver’s that was exhibited in the Las Vegas: Human Bodies Exhibit. Describe which muscles you could see and what type of movements this body was attempting to display (flexion, abduction etc. )QUESTION 4 What is the purpose of cleavage during embryonic development? To allow the embryo to get larger To allow the embryo to begin to form organs To generate multiple layers of cells in the embryo To produce many cells quickly so that more protein production can occurQuestion 8. a) Name the three germ layers and describe their relative locations in embryos. b) Name two organs or organ systems that develop from each of the germ layers. a) The names of three germ layers are 1) Ectoderm 2) Mesoderm and 3) Ectoderm (Describe relative location) b) The ectoderm gives rise to the central nervous system and skin, the mesoderm specifies the development of several cell types such as bone, muscle, and connective tissue and the ectoderm cells become the linings of the digestive and respiratory system, and form organs such as the liver and pancreas.
