\"Image:<\/figure>\n\n\n\n

c. Endochondral ossification occurs within fibrous connective tissue membranes.
d. Most bones in the body are formed by intramembranous ossification.

a. During endochondral ossification, hyaline cartilage is broken down and replaced with bone.

Endochondral ossification is the formation of bone within hyaline cartilage. Beginning late in the second month of development, this process uses hyaline cartilage “bones” formed earlier as models, or patterns, for bone construction. It is more complex than intramembranous ossification because the hyaline cartilage must be broken down as ossification proceeds. Most bones below the base of the skull form by endochondral ossification.<\/p>\n\n\n\n

During infancy and childhood, the most important stimulus of epiphyseal plate activity is __________.<\/a><\/p>\n\n\n\n

What is the first stage in the healing of a bone fracture?<\/a><\/p>\n\n\n\n

formation of a hematoma

This is the first stage in the healing of a bone fracture. In order, here are the stages of bone fracture healing: (1) formation of a hematoma, (2) formation of a fibrocartilaginous callus, (3) formation of a bony callus, and (4) bone remodeling.<\/a><\/p>\n\n\n\n

Which of the following are correctly matched?<\/a><\/p>\n\n\n\n

a. compound fracture; the fractured bone ends penetrate the skin
b. non-displaced fracture; the fractured bone ends are misaligned
c. incomplete fracture; the bone is broken through
d. linear fracture; the break is perpendicular to the bone’s long axis

a. compound fracture; the fractured bone ends penetrate the skin

In a compound (open) fracture, the fractured bone ends penetrate the skin. Such open injuries carry a higher risk of infection.<\/p>\n\n\n\n

The correct order (from start to finish) of fracture repair is __________.<\/a><\/p>\n\n\n\n

hematoma formation, soft callus formation, bony callus formation, and bone remodeling

From start to finish, a fracture is repaired by (1) formation of a hematoma, (2) formation of a fibrocartilaginous callus, (3) formation of a bony callus, and (4) bone remodeling.<\/a><\/p>\n\n\n\n

Your patient is returning for follow-up 6 weeks after sustaining a nondisplaced fracture of his radius. He tells you that his forearm is no longer painful, but he is concerned that he can palpate a “lump” in the bone at the site of the healing fracture. What is your response?<\/a><\/p>\n\n\n\n

“That bump is a normal part of bone healing at this stage. As your body completes the process, the cells in your bone will gradually remodel it to its previous shape.”

Right! You understand the stages of bone healing, including the formation of callus and ultimate remodeling.<\/a><\/p>\n\n\n\n

Which of the following refers to a bone disorder found most often in the aged and resulting in the bones becoming porous and light?<\/a><\/p>\n\n\n\n

Osteoporosis refers to groups of diseases in which bone resorption outpaces bone deposit. The bones become fragile and easily fractured. The composition of the matrix remains normal, but bone mass declines, and the bones become porous and light. Osteoporosis occurs most often in postmenopausal women.<\/p>\n\n\n\n
