give a under microscophe slides a histological appearance of a cell on its normal, reversible and irreversible injury state
Step by step
Solved in 2 steps with 1 images
- Post a histological appearance of a cell on its normal, reversible and irreversible injury state (aside from what is presented from the lecture). Identify the cell/s involved and the specimen.Briefly explain the abnormal functioning of cell adhesion molecules (CAMs) incertain diseases (2 diseases ).Healing with permanents cell are reversible Select one: True False
- Identify if the statement is True or False. If the statement is false, identify what is incorrect and correct it. Cellular response to injury depends on nature, duration and severity of injury and Consequences of injury depend on type, state and adaptability of the injured cell. The causes of cellular injury can be a depletion of ATP, mitochondrial Damage, and entry of Calcium into the cell, increase reactive oxygen species (ROS), membrane Damage, DNA damage and Protein misfolding. Intracellular Ca++ is normally low and is sequestered in mitochondria and endoplasmic reticulum. Increased cytosolic Ca++ activates enzymes such as ATPase, phospholipases, proteases, endonucleases that can lead to cell injury and death.Identify if the statement is True or False. If the statement is false, identify what is incorrect and correct it. Cellular adaptation often refer to reversible changes in size, number, phenotype or appearance, metabolic activity or functions of cells in response to adverse environmental conditions or internal bodily stresses Pathologic Hyperplasia refers to an abnormal increase in the number of cells, which are in a normal component of that tissue and are arranged in a normal fashion with subsequent enlargement of the affected part.Cell structure and function:
- The cell involved in bone resorption (destroy & remove unwanted bone) is:TRUE OR FALSE 1. A cell may revert back to its normal morphology and physiology after a pathologic adaptation 2. Apoptosis may be normal or pathological 3. Necrosis may be normal or pathologicalA loss of which would most likely result in metastatic spread of cancer? benign growth anchorage dependence angiogenesis contact inhibition
- The wound healing response involves all the following EXCEPT (choose the most incorrect answer): Initial blood clot formation is mediated by thrombin resulting in platelet aggregation and fibrin clots. Collagen deposition by vascular endothelial cells is critical in increasing the tensile strength of repaired wounds to approximately 100%. Angiogenesis involves the response of endothelial cells to growth factors such as vascular endothelial growth factor (VEGF) Activated fibroblasts produce collagen and fibronectin increasing the tensile strength of wounds Migration of fibroblasts in response to growth factors is an important component of the proliferation phaseEpithelial tissue is an important part of the body as a covering of surfaces and as a lining of the internal hollow organs.
