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 epithelial or in the underlying connective tissues? Explain your answer. Underlying connective tissues because bruises form underneath the skin and epithelial 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 areola connective tissue covered by emotionless. 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 (Orbs) and White Blood Cells (Webs) Which component of blood participates in blood clot formation? Platelets G. Dry. 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 covering it like skin does. The cells need to conduct electrical signals and those are done on their cell membranes which are relatively soft and fragile. H.
What types of cells would be found in the dead man’s brain? Stem Cells. Why didn’t the man’s brain regenerate new tissue to replace the tissue damaged by the parasites? Because the body responds to the invasion by leaning the tapeworm within a shell of scar tissue that eventually hardens into scarlet nodules. L. How is an understanding of tissues essential to the job performance of a medical professional like Dry. Diego? So you can discover how long a body has been dead, you can also discover mystery cases with dead patients. Chapter 5 Richards Story: A.
The doctor describes Richard as having two types of burns, “partial thickness” and “full thickness. ” Based on what you have learned about the skin, explain why a partial thickness burn is extremely painful and why it would heal faster than a full thickness burn. Because “full thickness” the epidermis is composed of quarantined stratified exogamous epithelium. Keratinous, the most numerous epidermal cells, are arranged in four or five different layers and produce keratin, a tough, fibrous protein that helps protect the skin and underlying tissues from abrasions, heat, microbes, and chemicals.
While in “partial thickness” corpuscles of touch that are sensitive to touch and/or free nerve endings, which initiate signals that produce sensations of warmth, coolness, pain, tickling and itching. B. Hospital staff members continually administer intravenous fluids, clean his mounds, administer antibiotics, and give him pain medication. Based on these observations, what functions of Richards skin have been compromised? Hair and Skin Glands What other functions of the skin would be of concern to the medical staff?
Nails C. Which component of skin is being damaged as Richard picks at his cuticles? The Nail Plate D. Why is it unlikely that Richard will be able to grow hair to cover the scars on his chest? The healing process is more complex than in epidermal wound healing. E. What takes place during the first phase of deep wound healing? An inflammatory phase. Relate this process to what Richard has experienced during the initial stages of his burn healing. The scabs that they scrap off. F.
The nurse notes that Richard has granulation tissue forming at the edge of his wounds. Will the formation of granulation tissue lead to normal appearing and normal functioning skin as Richard heals? Explain your answer. Yes, because granulation tissue is the tissue filling the wound. Deep to the epithelial cell bridge, fibroblasts migrate into the wound area and begin synthesizing collagen fibers and globetrotting to become scar tissue, and damaged blood vessels begin to regret.
