Most bone cancers increase the activity of what?
Most bone cancers increase the activity of osteoclasts, which are cells responsible for breaking down and resorbing bone tissue. This leads to bone destruction and weakened bones in individuals with bone cancer.
Which is greater osteoclast activity when calcitonin is present?
Osteoclast activity is decreased when calcitonin is present. Calcitonin inhibits bone resorption by osteoclasts, leading to decreased breakdown of bone tissue.
What attaches to bone and causes them to move?
Tendons and muscles. It's the tendons that attach the bone to the muscle.
The hormone released by the extrafollicular cells of the thyroid causes a decrease in the blood calcium level is?
Calcitonin is the hormone released by the extrafollicular cells of the thyroid that causes a decrease in blood calcium levels. It does this by inhibiting the activity of osteoclasts, which are responsible for breaking down bone tissue and releasing calcium into the blood.
What inhibits osteoclast activity?
Bisphosphonates, calcitonin, and denosumab are examples of medications that inhibit osteoclast activity by reducing bone resorption. Additionally, a high level of calcium in the blood can also inhibit osteoclast activity.
Most bone cancers increase the activity of what?
Most bone cancers increase the activity of osteoclasts, which are cells responsible for breaking down and resorbing bone tissue. This leads to bone destruction and weakened bones in individuals with bone cancer.
What do most bone cancers increase the activity of?
Osteoblasts and osteoclasts.
What causes leg extension during sexual activity?
An extra "Bone"
Mature bone grows and is reshaped by the simultaneous activity of which two cells?
The simultaneous activity of osteoblasts and osteoclasts is what causes the reshaping of mature bone as it grows. Bones are defined as rigid organs.
What happens when stress is applied to a bone it causes what type of activity to occur?
the minerals in the bone produce a weak electrical field that attracts osteoblasts.
Why is bone lost faster with aging than it is replaced?
Bone loss accelerates with aging due to a decrease in the activity of osteoblasts (cells that build bone) and an increase in the activity of osteoclasts (cells that break down bone). This imbalance leads to a net loss of bone tissue, resulting in conditions such as osteoporosis. Factors like hormonal changes, decreased physical activity, and inadequate nutrition can further contribute to accelerated bone loss in aging individuals.
What happens when osteoblast increases?
When osteoblast activity increases, there is an increase in bone formation and mineralization. This helps in building and strengthening the bones. Additionally, higher osteoblast activity can aid in the repair and remodeling of bones.
What is the medical term meaning decreased activity in bone marrow?
Myelosuppression is decreased activity in bone marrow.
Why do athletes have denser bones than non-active people?
Athletes consistently put force on their bones through activity. Force causes tiny electrical currents within the bone. These electrical currents stimulate the bone-forming activity of Osteoblasts. Since Osteoblasts produce bone tissue, this causes the bone to become denser and stronger.
Do anabolic steroids promote bone growth?
Yes, anabolic steroids can promote bone growth by increasing bone density and mineralization. They can stimulate osteoblast activity, leading to an increase in bone formation. However, prolonged use of steroids can also have negative effects on bone health, such as reducing bone strength and increasing the risk of fractures.
What does the skeletal system deal with homeostasis?
Homeostasis is maintained by the hormones that increase osteoblast activity to build bone, called calcitonin which is released by the thyroid gland, and the release of parathyroid hormone which increases osteoclast activity and is released by the parathyroid glands. As long as both of these function normally, the bone mass stays the same, this is a homeostatic state of bone. If it goes out of balance you will either build too much bone, or loose bone mass and develop osteoporosis.
