Answer: 1. Support—the skeletal system forms the body’s internal structural framework. The bones of the legs act as pillars to support the body trunk when we stand, and the rib cage supports the thoracic wall. 2. Movement—the skeletal muscles, attached to bones by tendons, use the bones as levers to move the body and its parts. 3. Protection—bones, such as the skull, thorax, and pelvis, protect the enclosed soft body organs. 4. Storage—fat is stored in the internal cavities of bones. Bones also serve as a storehouse for minerals, the most important being calcium and phosphorus. 5. Hematopoiesis—blood cell formation occurs within the red marrow of certain bones. Page Ref: 159 Bloom’s: 2) Comprehension 2) Differentiate between the functions of yellow marrow and red marrow. Answer: Yellow or red marrow may be found in the medullary (marrow) cavity of a long bone, depending on the age of the individual. Yellow marrow is adipose tissue that stores energy. Red marrow functions in blood cell production, a process known as hematopoiesis. Page Ref: 161 Bloom’s: 4) Analysis 2 3) List and explain the steps in the repair process of a simple fracture. Answer: Step 1 is hematoma formation. A hematoma, or blood-filled swelling, forms when bone breaks and blood vessels rupture. Bone cells are deprived of nutrition and die. Step 2 is fibrocartilage callus formation. The site of damage experiences growth of new capillaries into the clotted blood and disposal of dead tissue by phagocytes. Connective tissue cells of various types form a mass of repair tissue called fibrocartilage callus. This fibrocartilage callus contains several elements: some cartilage matrix, some bony matrix, and collagen fibers. This fibrocartilage callus acts to splint the broken bone, closing the gap. Step 3 is bony callus formation. As more osteoblasts and osteoclasts migrate into the area and multiply, fibrocartilage is gradually replaced by a callus of spongy bone (the bony callus). Step 4 is bone remodeling. Over the next few months, bony callus is remodeled in response to the mechanical stresses placed on it, so that it forms a strong, permanent patch at the fracture site. Page Ref: 169 Bloom’s: 1) Knowledge 4) Explain how the anatomy of compact bone differs from that of spongy bone. Answer: Compact bone is composed of osteons (Haversian systems). Concentric rings of matrix, called lamellae, are situated around a central (Haversian) canal. The rings and central canal constitute an osteon, or Haversian system. Other canals, called canaliculi, spread outward from central canals to connect to lacunae which house osteocytes. Spongy bone is open, airy, spiky and is composed of small, needlelike pieces of bone. Spongy bone lacks osteons and a network of canals. Page Ref: 159, 161-162 Bloom’s: 4) Analysis 5) Explain how bones are remodeled in response to parathyroid hormone (PTH). 2 Essentials of Human Anatomy and Physiology, 11e, (Marieb) 2 Chapter 7 The Nervous System 7.1 Multiple Choice Part I Questions Using Figure 7.1, identify the following: 1) The neural processes that convey incoming messages toward the cell body are indicated by . 1.
