Chapter 12 Bone Structure and Classification
1) A bone is considered to be a tissue of the skeletal system.
2) Which of the following is NOT a function of the bones?
A) To store inorganic salts
B) To serve as attachment sites for muscles
C) To help to buffer blood pH
D) To contain the cells that produce blood cells
E) All of these are functions of the bones.
3) The inorganic portion of the bone matrix consists of all of the following except
A) calcium phosphate.
B) calcium carbonate.
C) collagen fibers.
D) fluoride ions.
E) magnesium ions.
4) What is the function of osteoclasts in bone tissue?
A) They form blood cells.
B) They dissolve bone to release calcium salts into the blood.
C) They are the stem cells of bone tissue.
D) They are isolated within the bone matrix, and they function in bone homeostasis.
E) They form bone by depositing bone matrix.
5) Some of the large cranial bones, which have wide surfaces, and are sometimes curved, are classified as ________ bones.
A) short
B) long
C) irregular
D) flat
E) sesamoid
6) Some people develop bones in areas of compression in the hand or foot; these extra bones are classified as ________ bones.
A) long
B) sesamoid
C) irregular
D) short
E) flat
7) Each bone consists of either compact or spongy bone, but not both.
8) Which of the following is NOT true of the cartilage of the adult skeleton?
A) Intervertebral discs lie between adjacent vertebrae, and provide shock absorption for the vertebrae.
B) Costal cartilages connect the ribs to the sternum.
C) Articular cartilage is found on the ends of bones in joints, and reduces friction between joint-forming surfaces of the bones.
D) Costal cartilage, articular cartilage, and intervertebral discs are all composed of fibrocartilage.
E) All of these are true of the cartilage of the adult skeleton.
9) Which of the following structures would NOT be found in the long bones of a mature adult?
A) Epiphyses
B) Epiphyseal plates
C) Red bone marrow
D) Epiphyseal lines
E) Diaphyses
10) A small chamber occupied by an osteocyte is called a(n) ________.
A) lacuna
B) osteon
C) lamella
D) canaliculus
E) endosteum
11) By the time a person reaches adulthood, all of his/her red bone marrow has been converted to yellow bone marrow.
12) Looking at a radiograph of the hand, it can be seen that the metacarpals and phalanges are classified as ________ bones.
A) flat
B) irregular
C) sesamoid
D) long
E) short
13) Osteons are only found in compact bone.
14) Which of the following is NOT true of the structure of long bones?
A) Long bones contain an epiphysis at both ends.
B) The diaphysis and surfaces of the epiphyses consist of compact bone.
C) The periosteum surrounds the entire bone, even where there is articular cartilage.
D) Spongy bone makes up the internal portions of the epiphyses.
E) All of the following are true of the structure of a long bone.
15) Which of the following contain red bone marrow in the adult skeleton?
A) The proximal epiphyses of the femurs
B) The radius and ulna
C) The tibia and fibula
D) The phalanges of the hands and feet
E) None of these structures contain red bone marrow in the adult skeleton.
16) Concentric, interstitial, and circumferential lamellae all consist of ________.
A) spongy bone
B) hematopoietic cells
C) yellow bone marrow
D) layers of matrix
E) trabeculae
17) Chicken bones soaked in vinegar or hydrochloric acid overnight become flexible, because the acid dissolves the collagen fibers.
