Important functions of the skeletal system include
protection of the brain and soft organs.
A band of connective tissue that attaches a muscle to a bone is a(n)
Tendon
Ligaments attach
Bone to Bone
Chondroblasts produce
Cartilage matrix
The type of cartilage associated with bone function and development is
Hyaline cartilage
Perichondrium
the connective tissue sheath of cartilage
Cartilage Characteristics
contains chondrocytes located in lacunae
The proper sequence of events in bone repair is
External Callus
When blood calcium levels are low
ostoclast activity increases.
Which of the following is correctly
short bone - carpal bone
An example of a long bone would be
Tibia
An X-ray determines that Peter fractured the shaft of his humerus. The break is in the _____________ of the bone.
Diaphysis
Which of the following membranes covers the surface of a mature bone?
Periosteum
Some marrow of long bones is termed "yellow" marrow under normal conditions. The function of yellow marrow is to
Energy Reserve
Some marrow of long bones is termed "red" marrow. The function of red marrow is to
Bone remodeling
all of the above
The medullary cavity is
lined with an endosteum
Collagen and calcium hydroxyapatite are the prumary constituents
bone matrix
The compression (weight-bearing) strength of bone matrix is due to the presence of
Calcium
Bone remodeling and repair
Exposure of a bone to increased stress can lead to bone remodeling
The cell type that is responsible for maintaining bone once it has been formed is the
osteocytes
Which of the following cell types is responsible for breaking down bone matrix?
Osteoclasts
The primary function of osteoblasts is to
laydown matrix
The remodeling of bone tissue is a function of
osteoblast and osteoclast activity
Which of the following is correctly matched?
osteoclasts– responsible for resorption
Which of the following is mismatched?
parathyroid hormone – increases calcium loss in the kidneys
Concellous bone tissue
contains interconnecting plates called trabeculae
A passageway connecting neighboring osteocytes
canaliculus
Haversian systems
are the basic units in compact bone tissue.
The type of lamellae found in osteons (haversian systems) is
Concentric
Lamellar bone
is organized into thin sheets of tissue.
You would look for concentric lamellae
around the central canal of an osteon.
Intramembranous ossification
forms the bones of the roof of the skull.
Appositional
on the surface of the bone.
Arrange the following events in endochondral ossification in proper sequence:
(1)
Cartilage model
is formed
(2)
Chondrocytes
hypertrophy
(3)
Cartilage matrix
is calcified and chondrocytes die
(4)
Blood vessels
from the periosteum invade calcified cartilage bring in osteoblasts and osteoclasts.
(5)
Osteoblasts
deposit bone on the surface of the calcified cartilage the primary ossification center
If an X-ray shows a black area in the region of the epiphyseal plate,
the epiphyseal plate has not completely ossified
Long bones grow in the length at the
epiphyseal plate
The longitudinal growth of long bones ceases when
the epiphyseal plate is completely replaced with bone tissue.
