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...

Cross-bridge Cycle01:26

Cross-bridge Cycle

121.3K
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

5.0K
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...

The Effect of Aging on Tissues

3.1K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Disorders of the Skeletal Muscle01:28

Disorders of the Skeletal Muscle

1.5K
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...

Skeletal Muscle Anatomy

Skeletal muscle is the most abundant type of muscle in the body. Tendons are the connective tissue that attaches skeletal muscle to bones. Skeletal muscles pull on tendons, which in turn pull on bones to carry out voluntary movements.

    Summary

    Sarcopenia, a loss of muscle function, can be screened using the SARC-F questionnaire. Further examination via DXA or BIA confirms diagnosis, guiding early therapy and risk assessment for falls and mortality.

    Area of Science:

    • Geriatrics
    • Muscle Physiology
    • Public Health

    Background:

    • Sarcopenia is a generalized loss of muscle function, strength, and mass.
    • It is codable in Germany (ICD-10-GM: M62.50) since 2018.
    • Early identification and management are crucial for patient outcomes.

    Purpose of the Study:

    • To outline a primary care screening and diagnostic pathway for sarcopenia.
    • To emphasize the importance of early intervention and risk stratification.
    • To highlight the diagnostic criteria and recommended follow-up procedures.

    Main Methods:

    • Screening using the Sarcopenia Quality of Life (SARC-F) questionnaire.
    • Diagnostic confirmation via Dual-energy X-ray absorptiometry (DXA) or Bioelectrical Impedance Analysis (BIA) to determine skeletal muscle mass index.

  • Assessment of physical performance using gait speed, Timed Up and Go (TUG), and Short Physical Performance Battery (SPPB) to determine disease severity.

    • Main Results:

    • An elevated SARC-F score (≥4) indicates probable sarcopenia, prompting further investigation.
    • Reduced skeletal muscle mass index confirmed by DXA or BIA confirms sarcopenia diagnosis.
    • Physical performance tests help differentiate acute/chronic sarcopenia and assess disease progression and severity.

    Conclusions:

    • The SARC-F questionnaire is an effective primary care screening tool for sarcopenia.
    • Early diagnosis and therapy initiation, based on European consensus guidelines, can improve outcomes.
    • Sarcopenia significantly increases risks of immobility, falls, fractures, and mortality, necessitating comprehensive patient evaluation including comorbidities.
