Bone remodeling is critical in maintaining?
Bone remodeling is critical in maintaining bone strength and structure by constantly renewing and repairing bone tissue. It helps regulate calcium levels in the body, enables bones to adapt to mechanical stress, and plays a role in healing fractures. Hormones, physical activity, and nutrition all influence the bone remodeling process.
Compare and contrast the role of PTH hormone and mechanical forces acting on the skeleton?
Parathyroid hormone (PTH) regulates calcium levels in the blood by stimulating bone resorption and increasing calcium absorption in the intestines and kidneys. Mechanical forces on the skeleton, such as weight-bearing exercise, help maintain bone strength by promoting bone formation and remodeling. While PTH directly influences calcium regulation, mechanical forces indirectly influence bone health and density through the stimulation of osteoblast activity.
What are bones cells that liquefy bone matrix and release calcium to the blood called?
Bone cells that liquefy the bone matrix and release calcium into the blood are called Osteoclasts. Immature or matrix depositing bone cells are called osteoblasts.
Bone cells that liquefy bone matrix and release calcium to the blood are called?
Osteoclasts are bone cells responsible for breaking down and resorbing bone tissue, releasing calcium and minerals into the bloodstream. They play a crucial role in bone remodeling and maintenance.
Cells that free calcium from bone to maintain blood calcium levels are called?
Osteoclasts are cells responsible for breaking down bone tissue to release calcium into the bloodstream to maintain blood calcium levels.

What is the primary function of osteoclasts?
The primary function of osteoclasts is to break down and resorb bone tissue, allowing for bone remodeling and turnover. They help regulate calcium levels in the body and play a role in bone repair and growth.
What are bones cells that liquefy bone matrix and release calcium to the blood called?
Bone cells that liquefy the bone matrix and release calcium into the blood are called Osteoclasts. Immature or matrix depositing bone cells are called osteoblasts.
What percentage of bone calcium is exchanged each year during remodeling?
3 to 5 percent
HOW is calcium important to the skeletal system?
Calcium is important for bone health because it is a major component of bone tissue, providing strength and structure. It is essential for proper bone mineralization and helps to maintain bone density. Calcium also supports bone remodeling, which is the process of breaking down and rebuilding bone tissue.

What does Osteocytes secrete?
Osteocytes become surrounded by bone matrix and are relatively inactive, but do have the capability to produce components needed to maintain the bone matrix if needed. Lacunae osteoblasts change into osteocytes.
Ninety-nine percent of this nutrient is stored within the body in bone and becomes available to other tissues when the bone is broken down during remodeling?
Calcium
What is the function of the calcium salts in a bone?
Calcium salts in bone provide strength and rigidity to the bone structure. They help to mineralize the bone matrix, making it hard and capable of withstanding mechanical stress. Calcium salts also play a role in bone remodeling and storage of calcium for regulatory purposes in the body.
How does bone marrow regulate homeostasis?
Remodeling or bone turnover is the process of resorption followed by replacement of bone with little change in shape and occurs throughout a person's life. Osteoblasts and osteoclasts, coupled together via paracrine cell signalling, are referred to as bone remodeling units. The purpose of remodeling is to regulate calcium homeostasis, repair micro-damaged bones (from everyday stress) but also to shape and sculpture the skeleton during growth. == The process of bone resorption by the osteoclasts releases stored calcium into the systemic circulation and is an important process in regulating calcium balance. As bone formation actively fixes circulating calcium in its mineral form, removing it from the bloodstream, resorption actively unfixes it thereby increasing circulating calcium levels. These processes occur in tandem at site-specific locations. == Repeated stress, such as weight-bearing exercise or bone healing, results in the bone thickening at the points of maximum stress (Wolff's law). It has been hypothesized that this is a result of bone's piezoelectric properties, which cause bone to generate small electrical potentials under stress
