1. List and discuss the steps in the process of repairing a simple fracture. Phase 1: Blood forms a hematoma Phase 2: Cancellous bone forms near developing blood vessels, and fibrocartilage forms in more distant regions Phase 3: Callus replaces cartilage Phase 4: Osteoclasts remove l 'excess bone tissue that restores the new bone structure to the original shape2. List factors that can improve the transfer of information from short-term to long-term memory.⦁ Emotional state: We learn best when we are alert, motivated, surprised, and excited. Norepinephrine, a neurotransmitter involved in memory processing of emotionally charged events, is released when we are excited or “stressed,” which helps explain this phenomenon.⦁ Rehearsal – Rehearsing or repeating material improves memory.⦁ Association – Creating “new” information about “old” information already stored in LTM appears to be important for remembering facts.⦁ Automatic memory: Not all impressions that become part of LTM are consciously formed. A student who concentrates on a lecturer's speech may record an automatic memory of the lesson's tie pattern.3. Discuss strokes and their causes. Strokes occur when blood circulation to an area of ​​the brain is blocked and brain tissue dies from ischemia, a reduction in blood supply that impairs the supply of oxygen and nutrients. The most common cause of CVA is a blood clot blocking an artery in the brain. A clot may originate outside the brain or form on the rough inner wall of a narrowed cerebral artery due to atherosclerosis. Less frequently, strokes are caused by bleeding, which compresses brain tissue. Not all traits are "completed." Temporary episodes of reversible cerebral ischemia, called transient ischemic attacks (TIA), a... middle of paper......rient to rebuild the bone. Damage to a nutrient artery will reduce the supply of these building materials and may slow the healing process.6. What new technologies could be used to improve fracture repair if healing is delayed or impaired? For a slowly healing fracture, new techniques that promote healing include electrical stimulation, which promotes the deposition of new bone, and ultrasound treatments, known for speed of healing.7. What are the chances that Ms. DeStephano's knee cartilage will regenerate? Why? At age 45, Ms. DeStephano will most likely not regenerate the cartilage in her knee. Cartilage damage that occurs during adulthood heals slowly, due to the avascular nature of cartilage, and is irreparable. Surgical removal of cartilage fragments to allow better movement of the joint is the usual treatment for this type of damage.
