What else can I help you with?
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.
How does exercise increase calcium stores?
Exercise, particularly weight-bearing and resistance activities, promotes bone health by stimulating bone remodeling. When you engage in physical activity, the mechanical stress placed on bones encourages the activity of osteoblasts, the cells responsible for bone formation. This process enhances the uptake of calcium from the bloodstream into the bone matrix, thereby increasing calcium stores. Additionally, exercise can improve overall hormonal balance, including hormones that regulate calcium metabolism, further supporting bone density.
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 do most bone cancers increase the activity of?
Osteoblasts and osteoclasts.
What cellular activity causes increase in bone mass?
osteoblasts secrete matrix; bone deposition
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.
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 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 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.
What can be revealed by microscopic examination of bone marrow?
Microscopic examination of bone marrow can reveal leukemia, granulomas, myelofibrosis, myeloma, lymphoma, or metastatic cancers, bone marrow infection, and bone disease.
A disease resulting from abnormal proliferation of stem cells in bone marrow?
This cancer type is called myeloma.
