What cellular activity causes increase in bone mass?
osteoblasts secrete matrix; bone deposition
A disease resulting from abnormal proliferation of stem cells in bone marrow?
This cancer type is called myeloma.
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 medical equipment is used in bone marrow aspiration?
The main equipment used in bone marrow aspiration includes a syringe, a needle, local anesthesia, and possibly a biopsy needle to obtain a sample of bone marrow from the hip bone or breastbone. The samples are then analyzed in a laboratory to diagnose various blood disorders and cancers.
What hormone is the most important stimulus of epiphyseal plate activity?
The growth hormone is the most important stimulus of epiphyseal plate activity, as it is responsible for stimulating the growth of bones during childhood and adolescence. It acts on the epiphyseal plates to promote bone growth and elongation.
What do most bone cancers increase the activity of?
Osteoblasts and osteoclasts.
What cellular activity causes increase in bone mass?
osteoblasts secrete matrix; bone deposition
Are most primary bone tumors sarcomas?
Most primary bone tumors are benign.Malignant primary bone tumors account for fewer than 1% of all cancers diagnosed in the United States.
What cancers were treated by polonium and radium?
Polonium is not used for the treatment of cancers. Radium is used to treat bone cancers.
What is the medical term meaning cancer of the bone?
Most cases of bone marrow cancer are a result of cancer cells entering the bone marrow from other cancers in the body, such as Breast cancer, prostate cancer, or lung cancer. The primary bone cancers are called osteosarcoma, chondrosarcoma, Ewing's sarcoma, and malignant fibrous histiocytoma. Then there are other kinds of bone marrow cancers that are associated with a dysfunction in the development of blood cells that start out as pluripotent stem cells. These cncers include leukemia and lymphomas. A type of bone cancer that ocurrs in the red bone marrow is called multiple MYELOMA.
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 cancers does Neutron radiation attack?
It is especially effective for the treatment of inoperable salivary gland tumors, bone cancers, and some kinds of advanced cancers of the pancreas, bladder, lung, prostate, and uterus
Is bone cancer a inherited cancer?
Cancers are not "inherited", though a genetic predisposition to them can be.
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.
Does bone cancer commonly start in the bone?
Actually, the opposite is true. Approximately 80% of bone cancers are secondary, such as metastasis from primary tumors in soft tissue. Only about 20% of bone cancers actually start in the bone and then metastasize to soft tissues and other locations.
What is the medical term meaning decreased activity in bone marrow?
Myelosuppression is decreased activity in bone marrow.
Does cadmium cause cancer of the spine?
While cadmium has been shown to cause several types of cancer, it has not been associated with bone cancers or spinal cancers.
