Exam 6: Bones and Bone Tissue

What accounts for the majority of bone (osseous) tissue matrix?

Explain how primary bone differs from secondary bone.

What hormone promotes an increase in the activity of osteoclasts?

Six ^-year ^-old Matthew broke his femur and one of his epiphyseal plates was damaged. Explain the role of the epiphyseal plate in longitudinal growth and predict the effects of a damaged epiphyseal plate on his future longitudinal growth.

Hematopoiesis occurs in both the red and yellow marrow of bones.

The epiphyseal plate is a layer of compact bone from which longitudinal growth occurs.

Who experiences a greater amount of bone deposition: a person who routinely exercises or a sedentary person? Explain your choice.

Charlie has a break in the shaft of his thigh bone. He broke the:

What stimulates the release of parathyroid hormone (PTH)?

Spongy bone resists forces from many directions and forms a protective framework for the red bone marrow.

Blood cells are made in the red bone marrow of bones, a process known as:

Which cells participate in the process of bone deposition?

Can ossification occur without calcification during longitudinal growth? Explain.

Why does the medullary cavity develop during endochondral ossification? Explain.

A hypothetical drug reduces osteoblast activity, but has no effect on osteoclast activity. Predict the effects of this hypothetical drug on bone resorption and bone deposition.

Bone is the most important storehouse in the body for:

Bone growth and remodeling depends on adequate intake of:

Diploë refers to spongy bone in flat bones.

Cells that develop into osteoblasts are:

The process of ossification begins at a primary ossification center in both intramembranous and endochondral ossification.
