Classification & Function: 10 How many bones are in the human skeleton? Answer: 206 named bones
Classification & Function: 20 What are four shapes that bones are classified into? Answer: Long, short, flat & irregular bones
Classification & Function: 30 Name 3 of the 5 functions of bones. Answer: Support, protection. Movement, Mineral & growth factor storage, blood cell formation
Classification & Function: 40 Which bones belong to the appendicular skeleton? Answer: Bones of upper & lower limbs and the girdles (shoulders & hips)
Classification & Function: 50 What is hematopoiesis and where does it occur? Answer: Blood cell formation. Occurs in the marrow cavities of certain bones
Bone Structure: 10 A Proximal Epiphysis B Diaphysis Identify the structures labeled on the picture. C Distal Epiphysis D Articular cartilage (Be sure to use the letters)
Bone Structure: 20 1. What membrane covers the outside of bone? Answer: Periosteum 2. What membrane covers the inside of bone and trabeculae? Answer: Endosteum
Bone Structure: 30 Draw a cross section of an osteon and label the following structures: Lamella Osteocyte Central Canal
Bone Structure: 40 What are the organic components of bone? Answer: cells (osteogenic, osteoblasts, osteocytes & osteoclasts) and osteoid.
Bone Structure: 50 What is diploë? Answer: The spongy bone in flat bones
Bone Development: 10 What is ossification? Answer: the process of bone formation
Bone Development: 20 Before week 8, the skeleton is made of fibrous membranes and hyaline cartilage? Why? Answer: They are flexible & resilient and can accommodate mitosis
Bone Development: 30 Which bones are formed through intramembranous ossification? Answer: A membrane bone, cranial bones of the skull and the clavicles
Bone Development: 40 Once ossification is complete in a long bone, what two locations still have hyaline cartilage? Answer: on the epiphyseal plate and articular cartilages
Bone Development: 50 Which hormone stimulates epiphyseal plate activity during infancy and childhood? Answer: Growth Hormone
Remodeling & Repair: 10 Bone remodeling involves two processes (bone deposit and bone resorption). What two factors control when/where these processes occur? Answer: Negative feedback hormonal mechanism, maintains Ca +2 homeostasis in blood. The othere responds to gravitational & mechanical forces acting on skeleton
Remodeling & Repair: 20 Which hormone is released when calcium levels in the blood decline? Answer: Parathyroid Hormone (PTH)
Remodeling & Repair: 30 Comminuted fractures are more common in while fractures are common in children. Answer: Aged, Greenstick
Remodeling & Repair: 40 Draw a quick sketch of a long bone being loaded (stressed) that shows why they can hollow out to make the medullary cavity. Answer: see p. 190
Remodeling & Repair: 50 Write the type of fracture to match the descriptions; 1. Bone ends are out of alignment. a) Displaced fracture 2. Bone broken through. a) Complete Fracture 3. Orientation of break is parallel to long axis of bone. a) Linear fracture 4. Bone ends penetrate skin. a) Open (compound) fracture
Random!: 10 What are the functions osteoblasts and osteoclasts? Answer: Bone builders, destroyers
Random!: 20 What is the function of Sharpey s fibers? Answer: Connects periosteum to bone
Random!: 30 How is red marrow and yellow marrow different? Answer: The difference between red and yellow bone marrow is the function that they carry out. Red bone marrow produces blood cells, is active and divides cells. Yellow bone marrow is the producer of blood cells during an emergency, is inactive and contains fat. Where do you find yellow marrow? Answer: Medullary cavity
Random!: 40 What are the three types of cartilage? Answer: Hyaline, Elastic, Fibrocartilage Circle the one that is most abundant.
Random!: 50 What are three common treatments and/or preventative measures against osteoporosis? Answer: Calcium & Vitamin D supplements, weight bearing exercises & hormone replacement therapy
