The type of bone that is adapted to withstand stresses that arrive from a limited range of directions is _____ bone.
4, 2, 1, 3
The following are major steps in the process of intramembranous ossification:
1. Clusters of osteoblasts form osteoid that becomes mineralized.
2. Osteoblasts cluster together to form an ossification center.
3. Small struts of bone called spicules radiate out from the ossification centers to join with neighboring spicules.
4. Osteoblasts differentiate within a connective tissue at the site of arterioles.
3, 1, 5, 4, 2
The following are major steps in the process of endochondral ossification:
1. Blood vessels invade the perichondrium.
2. Osteoclasts create a marrow cavity.
3. Chondrocytes enlarge and calcify.
4. Osteoblasts replace calcified cartilage with spongy bone.
5. The perichondrium is converted into a periosteum and the inner layer produces bone.
is released in larger concentrations earlier in life
Osteoclast-activating factor does all of the following, except that it
stimulates osteoblast activity
Parathyroid hormone functions in all of the following ways, except it
the minerals in the bone produce a weak electrical field that attracts osteoblasts
When stress is applied to a bone,
A condition that produces a reduction in bone mass sufficient to compromise normal function is
A fracture where the shaft of one bone is broken and the adjacent bone is bent is best described as a ______ fracture.
Small, flat, oddly shaped bones found between some of the large flat bones of the skull are called _____ bones.
________ bones develop inside the tendons and are most commonly located near joints at the knees, the hands, and the feet.
If a human femur is found lying in a field, a pathologist can determine the age, sex, and general appearance of the individual as a result of studying which part of the bone?
The ________ interactions allow bones to be strong, somewhat flexible, and highly resistant to shattering.
_________ bone reduces the weight of the skeleton and makes it easier for muscles to move the bones.
step 4, growth and marrow cavity creation
In which step of endochondral ossification does remodeling of the bone occur?
While on a school skiing trip in Colorado, Heidi falls and breaks her femur. What would you expect to see as part of her nursing assessment several hours after the fall?
the bones would be more flexible
How would increasing the proportion of organic molecules to inorganic components in the bony matrix affect the physical characteristics of bone?
When cartilage is produced at the epiphyseal side of the metaphysis at the same rate as bone is deposited on the opposite side, bones
decreased muscle response
Bill develops a benign tumor of the parathyroid glands, which causes the level of parathyroid hormone in his blood to be higher than normal. Which of the following would you expect to occur as a result of this condition?
Marry is 50 years old. During a checkup, a bone scan reveals that portions of her skeleton show greater than normal demineralization. After reviewing the test results, her physician suggests hormone therapy. What hormone will she prescribe for her patient?
