John Doe’s Story:
A. What types of tissues form the surface of the dead man’s skin? Muscle Tissue How does the structure of the skin normally protect the body? It is composed of cells that can contract to generate the physical force needed to move body structures and generate heat that warms the body. B. As the body was being moved, skin slid away from the underlying connective tissue. What is the normal function of connective tissue? It protects and supports the body and its organs.
Would the slippage of the dead man’s skin be due to decomposition of cell junctions or underlying connective tissues? Decomposition of cell junctions.
C. Would the bruises on the dead man have formed in the epithelia or in the underlying connective tissues? Explain your answer. Underlying connective tissues because bruises form underneath the skin and epithelia tissues are located on the body surface.
D. Why do the cartilaginous structures in the airway make a good “handle” to grab onto in removing the lungs and heart? So he could tear it to expose the organ.
E. As the medical examiner pulls out the thoracic and abdominal organs, the membranes within the body cavity provide little resistance. Why? Because of blood clots.
What are these membranes called and what are they made of? A serous membrane and it consists of areolar connective tissue covered by mesothelium.
F. The dead man’s body cavities contain clotted blood released when organs ruptured during the plane crash. What cells might you expect to find in blood? Platelets, Red Blood Cells (RBCs) and White Blood Cells (WBCs)
Which component of blood participates in blood clot formation? Platelets
G. Dr. Diego was careful to preserve the brain tissue, and didn’t dissect and analyze it immediately during his preliminary autopsy. Why is nervous tissue soft and fragile? It doesn't have bones or hard protective proteins...
