Bone Disorders01:29

Bone Disorders

5.7K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Bone Remodeling01:40

Bone Remodeling

40.7K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

Osteoclasts in Bone Remodeling01:31

Osteoclasts in Bone Remodeling

4.4K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

Essential Minerals for Bone Health01:31

Essential Minerals for Bone Health

6.8K
The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

Hormones and Bone Tissue01:17

Hormones and Bone Tissue

4.0K
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

The Functions of the Skeletal System01:22

The Functions of the Skeletal System

6.3K
The most apparent functions of the skeletal system are support, protection, and movement. However, bone tissue also performs several other critical metabolic functions. For one, the bone matrix acts as a reservoir for a number of minerals important to the functioning of the body, especially calcium and phosphorus. These minerals, present in the bone tissue, can be released back into the bloodstream when required. Calcium ions, for example, are essential for muscle contractions and controlling...

Area of Science:

  • Bone Biology and Mechanotransduction
  • Stress Physiology and Endocrinology
  • Osteoporosis Research

Background:

  • Physical stress (PS) is known to stimulate bone remodeling via mechanotransduction.
  • Emerging evidence suggests mental stress (MS) also impacts bone health, potentially causing osteoporosis and fractures.
  • MS effects are linked to the hypothalamic-pituitary-adrenal axis, influencing hormone and cytokine release.

Purpose of the Study:

  • To review the emerging role of mental stress (MS) in bone adaptation.
  • To explore the molecular cross talk between MS and PS on bone health.
  • To highlight new research directions, including intergenerational stress transmission and epigenetics.

Main Methods:

  • Review of existing literature on physical and mental stress and bone biology.
  • Analysis of studies on hypothalamic-pituitary-adrenal axis modulation by stress.
  • Synthesis of findings on molecular interactions between different stress types.

Main Results:

  • Mental stress (MS) can negatively affect bone structure and function.
  • Cross talk between MS and PS can have synergistic or preventative effects on bone disease.
  • Intergenerational transmission of stress and epigenetic modifications are novel considerations.

Conclusions:

  • Mental stress (MS) is an important factor in bone adaptation.
  • Understanding the interplay between MS and PS is crucial for bone health.
  • Further research into stress, epigenetics, and bone health is warranted.
