Cross-bridge Cycle01:26

Cross-bridge Cycle

108.6K
As muscle contracts, the overlap between the thin and thick filaments increases, decreasing the length of the sarcomere—the contractile unit of the muscle—using energy in the form of ATP. At the molecular level, this is a cyclic, multistep process that involves binding and hydrolysis of ATP, and movement of actin by myosin.

Bone Disorders

7.9K
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...

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...

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...

Overview of Protein Metabolism01:21

Overview of Protein Metabolism

4.4K
Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.
Amino acids play various roles in the body once they are absorbed into cells. They are restructured...

Cellular Adaptation I: Introduction and Atrophy01:23

Cellular Adaptation I: Introduction and Atrophy

57
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...

  • Gerontology
  • Muscle Physiology
  • Clinical Medicine

Background:

  • Sarcopenia, characterized by age-related muscle mass and function decline, significantly impacts aging outcomes like disability and mortality.
  • It is a growing focus for clinical research and pharmaceutical development.
  • Recent advancements include consensus definitions for diagnosis, aiding clinical trials.

Purpose of the Study:

  • To review current understanding and diagnostic criteria for sarcopenia.
  • To explore lifestyle factors and potential therapeutic interventions.
  • To identify future research directions for sarcopenia management and prevention.

Main Methods:

  • Review of recent literature on sarcopenia definitions and prevalence.
  • Investigation of lifestyle factors (exercise, diet) and pharmacological treatments (ACE inhibitors).
  • Discussion of emerging research areas, including molecular mechanisms and life-course approaches.

Main Results:

  • New consensus definitions for sarcopenia diagnosis are emerging, based on muscle mass, strength, and physical performance.
  • Prevalence estimates suggest sarcopenia is common in older populations (around 13%).
  • Progressive resistance training is the most established intervention; diet's role is under investigation, and ACE inhibitors show potential for improving physical performance.
