What else can I help you with?
Do osteoblasts respond to parathyroid hormone?
yes
Describe bone physiology and the bone remodeling cycle?
Bone is broken down and built up all the time. This occurs on the surface of all bone types. About 10% of bone is replaced each year. Osteoblasts build bone. Osteoclasts break it down. Calcium is needed for this process.
Are cells that digest old bone in preparation for new bone growth?
Osteoclasts. They are a type of phagocytic cell, similar to the macrophage.
If There are five main types of bone cells in bone tissue what they are?
. Osteogenic cells respond to traumas, such as fractures, by giving rise to bone-forming cells and bone-destroying cells. Osteoblasts (bone-forming cells) synthesize and secrete unmineralized ground substance and are found in areas of high metabolism within the bone. Osteocytes are mature bone cells made from osteoblasts that have made bone tissue around themselves. These cells maintain healthy bone tissue by secreting enzymes and controlling the bone mineral content; they also control the calcium release from the bone tissue to the blood. Osteoclasts are large cells that break down bone tissue. They are very important to bone growth, healing, and remodeling. The last type of cells are bone-lining cells. These are made from osteoblasts along the surface of most bones in an adult. Bone-lining cells are thought to regulate the movement of calcium and phosphate into and out of the bone.http://www.mnsu.edu/emuseum/biology/humananatomy/skeletal/cells.htmlholy cow ur good. thanx, thisll help me on my project. yahoo!
How does the skeletal system help maintain calcium levels in the blood stream?
The skeletal system helps maintain calcium levels in the bloodstream primarily through the actions of osteoblasts and osteoclasts. Osteoblasts are responsible for bone formation and can take calcium from the bloodstream to deposit it in bones, while osteoclasts break down bone tissue, releasing calcium back into the bloodstream when needed. This dynamic balance is regulated by hormones such as parathyroid hormone (PTH) and calcitonin, which respond to changes in blood calcium levels to ensure homeostasis. Thus, the skeletal system acts as both a reservoir and a regulator of calcium levels in the body.
What are bone cells that respond to the parathyroid hormone to destroy bone matrix and release calcium into the blood?
An osteoclast.
What is the condition called when a muscle is being stimulated but is not able to respond?
It is called muscle fatigue.
How do pigs respond to stimuli?
Pigs respond to stimuli in different ways. They may oink or squeal depending on how they are stimulated. They may also run.
When a muscle is being stimulated but is not able to respond because of oxygen deficit the condition is called what?
Muscle fatigue
When a muscle is being stimulated but is not able to respond because of oxygen deficit the condition is called?
Muscle fatigue
When a muscle is being stimulated but is not able to respond due to oxygen debt the condition is called?
Fatigue
Where are osteoclasts most active?
Osteoclasts are most active in areas of bone that are actively being remodeled, such as at sites of bone growth, repair, or remodeling due to stress or strain. They are particularly active in the regions of bone surfaces that require resorption to maintain bone structure and respond to mechanical loading.
