Rasmussen College - BSC 2346 Module 04 Case Study 2: Bone Tissue, Complete solution.

Document Content and Description Below

Module 04 Case Study: Bone Tissue Part I— “Marissa” Questions 1. Describe bone tissue and the role each component plays in bone physiology and remodeling. What is the difference between compa ... ct and spongy bone? (2 points) - Osteoclasts break down old bones. Osteoblasts build new bones and osteogenic performs mitosis. - Compact bone is hard and dense. Spongy bone is porous and filled with red bone marrow. 2. Explain the relationship between calcium and bones. (1 point) - Calcium helps make bones stronger and build bone density. 3. Explain how the body controls calcium levels in the bones and blood. Be sure to describe the roles of parathyroid hormone (PTH) and calcitonin in detail. (2 points) -PTH helps increase calcium absorbed in the intestinal tract and decrease loss of calcium through the kidneys. -Calcitonin decreases the absorption of calcium in the intestinal tract and increases the loss of calcium in the kidneys. 4. Explain specifically how osteoporosis affects the bone matrix and the normal bone remodeling cycle. (1 point) - Osteoporosis makes the osteoclasts break down bones faster than osteoblasts can build new bones. 5. Discuss what scientists know about the genetics behind osteoporosis. (1 point) - Osteoporosis may be genetic. If someone in your family has osteoporosis than you are more likely to get it. [Show More]
