Changes in the Appendicular Skeleton with Age01:09

Changes in the Appendicular Skeleton with Age

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

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

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

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

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

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 loss of muscle mass and strength in older adults, significantly contributes to mobility disability. Strength training is the only proven treatment, though new pharmacological options are under investigation.

Area of Science:

  • Gerontology
  • Muscle Physiology
  • Clinical Medicine

Context:

  • Sarcopenia, characterized by loss of muscle mass, strength, and quality, is prevalent in the elderly.
  • It is a major contributor to mobility disability in older populations, highlighting the need for effective interventions.
  • Current assessment methods for sarcopenia lack universal consensus in clinical practice and research.

Purpose:

  • To review the current understanding of sarcopenia, its contributing factors, and treatment strategies.
  • To emphasize the need for standardized clinical assessment tools for sarcopenia.
  • To explore the potential of emerging pharmacological treatments alongside established interventions.

Summary:

  • Sarcopenia is multifactorial, influenced by reduced physical activity, hormonal changes, and inflammation.
  • Strength training is currently the sole evidence-based intervention for treating and preventing sarcopenia.
  • No pharmacological treatments have demonstrated definitive efficacy, but ongoing trials may offer future therapeutic avenues.

Impact:

  • Understanding and treating sarcopenia can significantly reduce mobility disability in the elderly.
  • Identifying specific elderly populations for clinical trials is crucial for targeted sarcopenia therapies.
  • Incorporating the prevention of mobility disability as a key outcome measure in sarcopenia research is essential.
