Overview of Skeletal Muscle01:15

Overview of Skeletal Muscle

15.7K
Skeletal muscles are composed of a bundle of muscle fibers and are attached to bones through tendons. Each skeletal muscle fiber is a single muscle cell. The sarcolemma, the plasma membrane of a skeletal muscle cell, consists of a lipid bilayer and glycocalyx that supports muscle fibers. The sarcolemma extends into the muscle cells to form tubular structures called transverse or T-tubules. Each side of the T-tubules consists of a membrane-bound structure called the sarcoplasmic reticulum,...

Bone Disorders01:29

Bone Disorders

5.8K
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...

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...

Changes in the Appendicular Skeleton with Age

3.9K
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...

The Functions of the Skeletal System01:22

The Functions of the Skeletal System

6.5K
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...

Cross-bridge Cycle01:26

Cross-bridge Cycle

123.9K
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.

Area of Science:

  • Gerontology
  • Muscle Physiology
  • Public Health

Background:

  • Sarcopenia, characterized by age-dependent loss of muscle mass and function, is prevalent in older adults and linked to adverse health outcomes.
  • Increased awareness and accurate identification of sarcopenia in community and geriatric settings are crucial due to its impact on quality of life, disability, and mortality.
  • Current research on sarcopenia prevention and treatment is advancing, but significant questions remain regarding effective interventions.

Purpose of the Study:

  • To address the need for standardized identification of sarcopenia by utilizing the FNIH Sarcopenia Project's operationalization.
  • To introduce the 'physical frailty and sarcopenia' (PF&S) condition, defined by low physical performance and low muscle mass.
  • To evaluate the efficacy of a multi-component intervention for preventing mobility disability and other adverse health outcomes in older adults with PF&S.

Main Methods:

  • Operationalization of sarcopenia using quantitative and qualitative muscle loss dimensions.
  • Definition of physical frailty and sarcopenia (PF&S) based on Short Physical Performance Battery (SPPB) scores and FNIH-defined low muscle mass.
  • Conducting a randomized controlled trial (RCT) to test a multi-component intervention.

Main Results:

  • The FNIH Sarcopenia Project provides an objective, standardized, and clinically relevant definition of sarcopenia.
  • The PF&S definition integrates low physical performance and low muscle mass, facilitating targeted interventions.
  • The RCT is designed to yield significant findings on the intervention's efficacy in mitigating adverse outcomes.

Conclusions:

  • The FNIH operationalization of sarcopenia is expected to accelerate clinical translation and public health adoption.
  • The PF&S construct offers a refined approach for identifying older adults at high risk.
  • The multi-component intervention holds promise for preventing mobility disability and improving health outcomes in this population.
