| Question | Answer |
|---|---|
| Which of the following is not part of the axial skeleton? skull ribs vertebrae humerus | humerus |
| Which of the following is an example of a flat bone? patella scapula vertebrae femur | scapula |
| What is the name given to each end of a long bone? diaphysis epiphyseal plate epiphysis periosteum | epiphysis |
| As adults age, this covering on the ends of their bones deteriorates, causing bones to make grinding noises as they move past each other. epiphyseal plate, periosteum, articular catilage, lamellae | articular cartilage |
| You haven't been eating your vegetables or drinking milk. The calcium in your blood is, therefore, quite low. What hormone will break down your bone to put calcium back into your blood? PTH, calcitonin, osteoid, hydroxyapatite | PTH |
| Which part of the bone matrix gives it compressive strength? collagen hydroxyapatite marrow osteoid | hydroxyapatite |
| A bone cell that is mature and completely surrounded by matrix is an ____________________. osteoblast osteoclast osteocyte | osteocyte |
| which type of tissue contains trabeculae? spongy or compact | spongy |
| What is found in the spaces between trabeculae? lamellae, red bone marrow, empty space, haversian canals | red bone marrow |
| What would you find running through the canaliculi? haversian tubes, blood vessels, bone marrow, processes of osteocytes | processes of osteocytes |
| What is the mass of blood that forms first when a broken bone is being repaired? hematoma, callus, cartilage, osteoclast | hematoma |
| Which types of joints are immovable or only slightly movable? synovial&carilaginous, synovial &fibrous, cartilaginous&fibrous, fibrous&irregular | cartilaginous & fibrous |
| Which type of synovial joint has the greatest range of motion? Ball and socket, hinge, ellipsoid, plane/gliding joint | ball and socket |
| What type of joint is proximal to your knee joint? saddle, ball&socket, pivot, gliding | ball and socket |
| The process of incorporating calcium & minerals into cartilage to become bone is ______. hematopoiesis, bone marrow production, suturing, ossification | ossificaiton |
| True or false: Bone ossifies on the epiphysis side of the epiphyseal plate. | false |
| True or false: Bone will be created or dissolved to preserve calcium levels | true |
| true or false: Bones are classified by their shape | true |
| true or false: Bones contain a matrix of calcium and fibers | true |
| Which type of fracture is incomplete? transverse, oblique, spiral, greenstick | greenstick |
| What is the correct order of the vertebral column from cranial to caudal? | cervical, thoracic, lumbar, sacral, coccyx |
| Which of the following structures attaches bone to bone? tendons, cartilage, joints, ligaments | ligaments |
| Which structure is made up of osteons? spongy bone, compact bone, red bone marrow, synovial fluid | compact bone |
| In which structure does hematopoiesis occur? yellow bone marrow, red bone marrow, compact bone, suture | red bone marrow |
| Which structure connects muscle to bone? ligament, tendon, suture, synovial fluid | tendon |
| Which structure provides cushion and reduces friction between bones? synovial fluid, yellow bone marrow, compact bone, osteocyte | synovial fluid |
| Which structure stores fat? red bone marrow, yellow bone marrow, spongy bone, synovial fluid | yellow bone marrow |
| Which structure is made up of trabeculae? compact bone, spongy bone, suture, tendon | spongy bone |
| Which cell uses processes to communicate? osteocyte, tendon, red bone marrow, suture | osteocyte |
| Which structure is an immovable junction between two bones? synovial fluid, suture, tendon, spongy bone | suture |
| An intracranial hematoma would be best described as: mass of blood found in the skull//femur; cartilage injury in the skull, fracture of the vertebral column | mass of blood found in the skull |
| Where would you expect to find the femoral artery? in the upper leg, near the femur; in the forearm, near the radius; in the skull, near the frontal bone; in the lower leg, near the fibula | in the upper leg, near the femur |
| What are the four main steps of the bone ossification process? Include the division of chondrocytes, cartilage deteriorating, osteoclast secretion, and osteoblasts forming spongy bones | Tall columns of chondrocytes divide → cartilage begins to deteriorate → osteoclasts secrete acid to enlarge the medullary cavity → osteoblasts begin to form spongy bone |
| Why is it important to properly splint a fractured bone along with surrounding joints? | Tendons and ligaments attached to the broken bone can still cause it to move if surrounding bones are not immobilized. |
| What is a difference between infant and adult bones? | Adults may have yellow marrow in the medullary cavity and an epiphyseal line rather than an epiphyseal plate. |
| Which bone cell secretes acid to enlarge the medullary cavity as bone grows? | osteoclast |
| Why are the curves of the vertebral column helpful? | They allow weight to be evenly distributed and aid balance. |
| How does long-term spaceflight affect the skeletal system? | It reduces bone density because microgravity does not place enough resistance on bones. |
| Which prevents skeletal effects of long-term spaceflight? Astronauts exercise with resistance to simulate gravity, Astronauts increase joint immobilization; Astronauts avoid all weight-bearing exercise; Astronauts eliminate calcium from the diet. | Astronauts exercise with resistance to simulate gravity. |
| Which bone marking is defined as a round or oval hole through bone? condyle, foramen, fossa, tuberosity | foramen |
| Which bone marking is defined as a large, rough projection? tuberosity, meatus, sinus, foramen | tuberosity |
| In the compact bone diagram, what structure is labeled as the central opening of an osteon? central haversian canal, trabecula, epiphyseal line, medullary cavity | central haversian canal |
| In a long bone, which region is the shaft? epiphysis, metaphysis, diaphysis, articular cartilage | diaphysis |
