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.

The micro-dissected explants technique is a robust and reliable method for isolating proliferative skeletal muscle cells from juvenile, adult or embryonic muscles as a source of skeletal muscle stem cells. Uniquely, these cells have been clonally derived to produce skeletal muscle stem cell lines used for in vivo transplantation.

Classification of Skeletal Muscle Fibers

Skeletal muscles continuously produce ATP to provide the energy that enables muscle contractions. Skeletal muscle fibers can be categorized into three types based on differences in their contraction speed and how they produce ATP, as well as physical differences related to these factors. Most human muscles contain all three muscle fiber types, albeit in varying proportions. Slow-Twitch Muscle Fibers Slow oxidative, muscle fibers appear red due to large numbers of capillaries and high levels of...

What is the Skeletal System?

Overview The adult human skeleton comprises 206 bones that are connected through cartilage, tendons, and ligaments. The skeleton provides a rigid framework for the human body, protects internal organs, and enables movement and locomotion. The human skeletal system consists of the axial and appendicular skeletons. Bone tissue is continuously built up and chewed away by specialized bone cells which are essential to overall health. Dysregulated bone cells and incorrect levels of chemical...
FAQs
Bone remodeling depends on coordination between two opposing cellular activities: osteoclasts resorb older bone, while osteoblasts form new tissue. Skeletal health is supported when these activities maintain functional integrity rather than allowing deterioration to dominate. This balance matters clinically because disrupted remodeling can contribute to reduced strength and greater vulnerability to injury.
Mineral balance and mechanical loading act as regulatory influences on skeletal strength. Mineral availability supports bone strength, while loading provides a physical influence associated with maintaining skeletal condition. Medical guidance can therefore consider both factors when aiming to preserve strength, rather than treating bone integrity as independent of nutrition or movement.
Joints and supporting tissues contribute to the system's ability to enable movement and protect organs alongside the structural role of bone. Their condition therefore affects functional outcomes such as mobility. This broader view is especially relevant in medicine, where arthritis and other disorders may impair function even when the clinical concern is not limited to bone strength.
Clinical assessment translates skeletal findings into decisions about prevention, diagnosis, and management. In medicine, it helps identify concerns associated with osteoporosis, fractures, arthritis, or other disorders that increase injury risk or impair mobility. Its value is practical: assessment connects the condition of the skeletal system with an appropriate care strategy.
Skeletal health is relevant across the lifespan because bone strength and function must be preserved over time. Medical evaluation, nutritional guidance, physical activity guidance, and targeted treatment can work toward that goal. Together, these approaches support prevention and management of conditions that threaten mobility or increase injury risk.
Nutritional and physical activity guidance should aim to preserve bone strength and overall function. These recommendations address two established influences on skeletal condition: mineral balance and mechanical loading. Used as part of medical care, they can support prevention and long-term maintenance rather than serving only as responses after a fracture or mobility problem has developed.
