Chapter 6, Problem 3CT
Summary Introduction
To determine:
The reason in which a person experiences a dramatic decrease in bone density in a weightless environment along with suggestions to slow the loss of bone tissue.
Introduction
Bone density refers to the amount of bone minerals in bone tissue. To determine the bone density, one can measure the gram of calcium and other bone minerals that how they are packed into the bone segments.

Because of the constant exchange of blood calcium and bone calcium, the concentration of calcium ions in the blood and tissue is very steady. Describe the process of calcium mobilization in bone tissue.
Using a cause-and-effect sequence, explain how an inadequate intake of dietary calcium or vitamin D can cause bone resorption. Also, describe the cause-and-effect sequence whereby an adequate intake of calcium and vitamin D may promote bone deposition.
One of the major promoters of bone remodelling and increased bone thickness is mechanical stress on the bone. Explain this mechanism and give an example.

- Osteoporosis is a condition in which the activation of certain signal transduction pathways causes calcium to be removed from bones, leaving them brittle and more likely to break under moderate pressure. Current research suggests that osteoporosis can be initiated under conditions of low cal- cium intake in order to increase the availability of calcium for other biological roles in the body. Which of the following describes the conditions that would be most likely to initiate osteoporosis? A B с D insufficient amounts of calcium to allow the replication of DNA molecules during cell division insufficient amounts of calcium to maintain the membrane potential established by the sodium-potassium pump insufficient amounts of calcium ions to facilitate efficient transduction of neuronal signals insufficient amounts of calcium to be used in the fixation stage of the Krebs cycle in photosynthesisarrow_forwardWhat is rigor mortis?
