The flashcards below were created by user ChathamBio502 on FreezingBlue Flashcards. What would you like to do?


  1. True or false (if false, correct underlined portion of the statement to make it true):
    Most of the fibers in bone matrix are reticular fibers.
    FALSE: most of the fibers in the matrix of bone are collagen fibers
  2. True or false (if false, correct underlined portion of the statement to make it true):
    The central canals of bone deliver blood to the deep osteons.
    FALSE, the perforating canals deliver blood to the deep osteons. The central canals run parallel to the long axis of the bone and do not reach the deep osteons.
  3. What structure is described below?

    This is the location of the osteocytes that make up the matrix of bone.
    The lacunae
  4. What structure is described below?

    This component of bone better enables bone to resist compressive stresses.
    The mineral component.
  5. What structure is described below?

    This division of the skeleton includes atlas, the temporal bones, and the ribs.
    The axial skeleton
  6. A joint that permits free movement (a large range of motion) is called

    A) a synarthrosis.
    B) a hinge joint.
    C) a synovial joint.
    D) a synchondrosis.
    E) an amphiarthrosis.
    C
  7. Which of the following is the correct classification for the articulation between the parietal bones?
    A) gomphosis
    B) suture
    C) syndesmosis
    D) synchondrosis
    E) synostosis
    B
  8. The structure that surrounds the entire structure of a diarthrotic joint is called (a)
    A) meniscus.
    B) joint capsule.
    C) synovial membrane.
    D) bursa.
    E) None of the answers are correct.
    B (diathrosis is another term for a synovial joint. In synovial joints, the synovial membranes attach to the margins of the hyaline cartilage, but the joint capsule encloses the entire joint)
  9. The radial structures in contact with the proximal ulna include the

    A) ulnar notch.
    B) head.
    C) radial tuberosity.
    D) antebrachial joint.
    E) ulnar notch and head.
    B
  10. The capitulum is a part of the

    A) scapula.
    B) ulna.
    C) humerus.
    D) radius.
    E) clavicle.
    C
  11. Most of the anterior surface of the scapula is formed by the

    A)  infraspinous fossa.
    B) glenoid cavity.
    C) subscapular fossa.
    D) supraspinous fossa.
    E) mandibular fossa.
    C
  12. In the hand, ________ bones articulate with
    proximal end of the proximal phalanges.
    The metacarpals
  13. The digit with only two phalanges in the hand is called the ________.
    Pollex
  14. The lateral end of the clavicle articulates with the ________ of the scapula.
    acromion process
  15. What bones make up the portion of the lower limb called the "leg"?
    The tibia and fibula
  16. Name one place in the lower limb where short bones are found.
    In the tarsus (the tarsal bones)
  17. What three bones unite to form the acetabulum?
    The ilium, the ischium and the pubis
  18. Why are the lumbar vertebrae larger than the cervical and thoracic vertebrae?
    Because they play an increased weight-bearing role (because they are more inferior and bear more of the mass of the upper body)
  19. Name one of the synovial joints of the skull
    Either the temporal mandibular joint or the atlanto-occipital joint
  20. What is the detriment of being a highly mobile joint?
    A highly mobile joint cannot also be a very strong joint. Joints can be mainly one or the other.
  21. On which bone is the mastoid process located?
    The temporal bone
  22. Which bones participate in the lambdoid suture?
    The parietal bones and the occipital bone
  23. In which bone is the foramen magnum located?
    In the occipital bone
  24. What is one of the distinguishing characteristics of thoracic vertebrae?
    • the look like giraffes when view posteriorly
    • the articulate with the ribs
  25. True or false (if false, correct the underlined portion to correct the statement):

    the upper dentition are located in the mandibular alveolar process.
    FALSE: the upper dentition is located in the maxillary alveolar process.
  26. True or false (if false, correct the underlined portion to correct the statement):

    The radius is lateral to the ulna
    TRUE
  27. True or false (if false, correct the underlined portion to correct the statement):

    The pollex is made up of two metacarpals.
    FALSE: two phalanges
  28. True or false (if false, correct the underlined portion to correct the statement):

    The gelnoid cavity is deepened by the acetabular labrum.
    FALSE: by the glenoid labrum
  29. Provide one of the functions of hyaline cartilage in synovial joints:
    • 1) it increases the articular surface area, thereby decreasing pressure acting across the joint surface
    • 2) reduces friction of the articulating bones
  30. Which bones participate in the knee joint?
    The tibia, the patella and the femur
