Changes in the Appendicular Skeleton with Age01:09

Changes in the Appendicular Skeleton with Age

3.2K
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Cellular Adaptation I: Introduction and Atrophy

70
Cells can adapt to environmental changes to maintain function and avoid injury, a process called cellular adaptation. Adapted cells exist in a reversible intermediate state with changes in size, number, phenotype, metabolism, or function. These responses help cells meet altered physiological or pathological demands; for example, enlargement of breast and uterine tissues during pregnancy. Early adaptations may enhance function, but persistent stress eventually causes tissue damage.Types of...

Spongy Bone01:09

Spongy Bone

12.8K
All bones comprise an outer layer of compact bone, and an interior made up of spongy bone tissue, also called cancellous or trabecular bone. In long bones, spongy bone tissue is mainly found in the interior of the epiphyses (broad ends of the bone).
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...

The Functions of the Skeletal System01:22

The Functions of the Skeletal System

6.4K
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...

Disorders of the Skeletal Muscle01:28

Disorders of the Skeletal Muscle

2.2K
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Compact Bone01:27

Compact Bone

22.4K
Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

Summary
This summary is machine-generated.

Sarcopenia, the age-related loss of muscle mass and function, is a key component of geriatric assessment. Differentiating it from cachexia is crucial for effective treatment strategies in elderly individuals.

Area of Science:

  • Geriatric Medicine
  • Muscle Physiology
  • Inflammology

Context:

  • Sarcopenia, the age-related loss of muscle mass and function, is increasingly recognized in geriatric medicine.
  • It is pathologically linked to the frailty syndrome, sharing common underlying factors like low-grade inflammation.
  • Distinguishing sarcopenia from cachexia is vital, as cachexia is less responsive to current treatments.

Purpose:

  • To define sarcopenia as a condition involving both muscle loss and reduced muscle function or strength.
  • To highlight the role of sarcopenia in comprehensive geriatric assessments.
  • To discuss the pathophysiological links between sarcopenia, frailty, and inflammation.

Summary:

  • Sarcopenia is characterized by age-related muscle mass and function decline, closely associated with frailty.
  • Low-grade inflammation is a central pathophysiological factor in sarcopenia and other geriatric syndromes.
  • Sarcopenic obesity presents a growing challenge, necessitating further research and clear diagnostic criteria.

Impact:

  • Improves the diagnostic framework for geriatric syndromes, particularly frailty.
  • Informs the development of targeted therapeutic strategies for age-related muscle decline.
  • Addresses the growing clinical challenge of sarcopenic obesity in the elderly population.
