Epithelia form continuous sheets of cells that cover surfaces in our body. They are important in the formation of membranes which act as a barrier and interface between compartments of the body. Choose an area of the body covered by epithelia (different from the ones your classmates have chosen) and explain how a break in this epithelial barrier might affect the functioning of a specific body membrane. After you post your initial post, reply to two or more of your classmates’ postings (Note that three additional postings are needed for an “Exemplary” grade).

In the last module, we discussed the legal use of DNA analysis in forensic medicine. In this discussion, we will take a look at some of the internal machinery of the cell. Organelles are essential for specific functions associated with a cell. For example, you would expect to find an abundance of mitochondria in a cell involved in energy requiring process, such as active transport of an ion. Select an organelle and discuss what functions might be effected in the body if this organelle was defective. Imagine that you have been summoned to a jury which will be considering the disposition of a murder case.
There has been a great deal of media coverage of this case and it has indicated that examination of DNA evidence will play an important role during the trial. The defense attorney asks you to explain your position on use of this type of evidence to determine guilt or innocence. What will you answer? Please explain your position. After you post your initial post, reply to two or more of your classmates’ postings (Note that three additional postings are needed for an “Exemplary” grade).
The Essay on Tissue Types Body Tissues Cells
Biology Assignment 1. Tissue types and their properties! Body tissues! The four core types of tissues in the body are; epithelial, connective, muscle and nervous. Each is designed for specific functions. Epithelial Tissues! Epithelial tissues are spread out all over the body. They cover all surfaces and also line body cavities and hollow organs. These tissues are also the major tissue in glands. ...
