Disorders of the Skeletal Muscle

2024
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...

An Introduction to Cell Metabolism

2023
In cells, critical molecules are either built by joining together individual units like amino acids or nucleotides, or broken down into smaller components. Respectively, the reactions responsible for this are referred to as anabolic and catabolic. These reactions require or produce energy typically in the form of a “high-energy” molecule called ATP. Together, these processes make up “Cell Metabolism,” and are hallmarks of healthy, living cells.JoVE’s introduction to cell metabolism briefly...

This protocol describes a procedure to study the respiration of mitochondria isolated from skeletal muscles. This method was adapted from Scorrano et al. (2007). The mitochondrial isolation procedure requires about 2 hours. The mitochondrial respiration can be completed in about 1 hour.

Zebrafish represent a powerful vertebrate model that has been under-utilised for metabolic studies. Here we describe a rapid way to measure the in vivo metabolic profile of developing zebrafish that allows the comparison of different mitochondrial function parameters between genetically or pharmacologically manipulated embryos, thereby increasing the applicability of this organism.

What is Metabolism?
0 Views •
2019
Overview Metabolism represents all of the chemical activity in a cell, including reactions that build molecules (anabolism) and those that break molecules down (catabolism). Anabolic reactions require energy, whereas catabolic reactions provide it. Thus, metabolism describes how cells transform energy through a variety of chemical reactions, which are often made more efficient with the help of enzymes. Metabolism Is the Sum of All of the Chemical Reactions That Take Place in an Organism
FAQs
These factors help maintain the mineral balance required for normal bone formation and remodeling. Disruption in any part of this biochemical network can alter calcium or phosphate availability and affect skeletal tissue. Examining the factors together is more informative than considering a single nutrient or hormone, because their interactions help explain changes in bone strength, structure, or mineralization.
Osteoblasts build bone, whereas osteoclasts resorb it. Healthy skeletal maintenance depends on coordinated activity between these cell types. When their balance becomes dysregulated, bone remodeling can shift toward inadequate formation or excessive loss, contributing to weakened bone or altered structure. This cellular relationship gives biochemical studies a way to connect molecular changes with skeletal outcomes.
The disorders described in this group do not produce identical skeletal changes. Osteoporosis is associated with fragile bones, while rickets and osteomalacia relate to impaired mineralization, with rickets also associated with impaired growth. Paget disease can alter skeletal structure. Comparing these outcomes helps distinguish whether the dominant problem involves strength, mineralization, growth, or remodeling.
Biochemical investigation focuses on calcium, phosphate, vitamin D, and parathyroid hormone, together with indicators related to bone-forming and bone-resorbing activity. These measurements can reveal disturbed mineral balance or altered regulation of remodeling. Interpreted in combination, they help clarify disease mechanisms and support a more informed understanding of why bone formation, mineralization, or structural maintenance has changed.
Biochemical study helps researchers and clinicians interpret biomarkers rather than viewing skeletal changes in isolation. Marker patterns can be considered alongside the pathways controlling mineral balance and the activities of osteoblasts and osteoclasts. This approach can clarify the underlying mechanism and connect laboratory findings with outcomes such as fragile bones, deformities, impaired growth, or fractures.
Understanding the disrupted pathway can inform nutritional, pharmacological, and hormone-based approaches to diagnosis and treatment. Nutritional strategies may address mineral-related factors, while pharmacological or hormone-based approaches may target dysregulated biochemical control. The appropriate direction depends on the mechanism identified through biomarker interpretation and assessment of calcium, phosphate, vitamin D, parathyroid hormone, and remodeling activity.
Biochemistry provides a common framework for comparing these conditions while recognizing their different skeletal outcomes. It links mineral balance and regulatory hormones with bone formation, mineralization, and remodeling. This perspective helps explain how distinct biochemical disturbances can lead to fragility, deformity, impaired growth, or structural alteration, and why biomarker interpretation is useful across multiple disorders.
