1. List and discuss the steps in the process of repairing a simple fracture.Step 1: Blood forms a hematomaStep 2: Spongy bone forms near the developing blood vessels and fibrocartilaginous bone forms in more distant areasStep 3: Bone calluses replace the cartilageStep 4: Osteoclasts remove excess bone tissue restoring the new bone structure to its original shape2. List the 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.⦁ Repetition – Repeating or repeating material improves memory. ⦁ Association – Linking “new” Information about “old” information already stored in the LTM appears to be important for remembering facts. ⦁ Automatic memory – Not all impressions that are part of the LTM are consciously formed. A student focused on a lecturer's speech can record an automatic memory of the lecture's tie pattern.3. Discuss strokes and their causes. Strokes occur when blood flow to an area of ​​the brain is blocked and brain tissue dies from ischemia, a reduction in blood supply that impairs the delivery of oxygen and nutrients. The most common cause of stroke is a blood clot that blocks an artery in the brain. A clot may originate outside the brain or form on the rough inner wall of a cerebral artery narrowed by atherosclerosis. More rarely, strokes are caused by bleeding that compresses brain tissue. Not all traits are “finished.” Temporary episodes of reversible cerebral ischemia, called transient ischemic attacks (TIA), a...... middle of paper ......laughs in order to rebuild the bones. Damage to a nutrient artery will decrease 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 fracture that is slow to heal, new techniques to promote healing include electrical stimulation, which encourages the deposition of new bone tissue, and ultrasound treatments, known to speed healing.7. How likely is it that the cartilage in Ms. DeStephano's knee will regenerate? For what ? At 45, Ms. DeStephano probably won't regenerate her knee cartilage. Cartilage lesions that occur in adulthood are slow to heal, due to the avascular nature of cartilage, and are irreparable. Surgical removal of cartilage fragments to allow better movement of the joint is the usual treatment for this type of damage..
