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

2019
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...
FAQs
Their shape and surface structure often reflect functional relationships with nearby tissues. Projections may indicate attachment regions for muscles, ligaments, or tendons, while openings and other features can mark routes used by nerves or blood vessels. Recognizing these relationships helps connect bone anatomy with movement, support, and the passage of important structures.
Skeletal landmarks provide stable reference points for locating and describing regions of the body. This shared framework allows anatomists and clinicians to communicate about bone position, joint relationships, and musculoskeletal structures more precisely. Consistent reference points also support comparison among physical examinations, anatomical studies, medical images, and procedural plans.
Variations in bone shape create projections, depressions, borders, and openings that correspond to different anatomical relationships. These features may accommodate attachments, define margins, or provide passageways for structures. Interpreting the surface as more than a simple outline helps explain how bones participate in movement, joint alignment, and support of associated tissues.
During examination, clinicians locate accessible bone features by palpation and use them as reference points for assessing posture, movement, and joint alignment. Differences in the expected position or relationship of these points may also help evaluate injury. The findings provide an anatomical basis for observing musculoskeletal structure and function directly.
Recognizing characteristic bone features helps clinicians orient medical images and identify the location of anatomical structures. Landmarks can support assessment of alignment and injury by providing consistent reference points for comparison. Their value extends across radiographs and other imaging approaches because they connect visible bone shape with the organization of the musculoskeletal system.
Clinicians can use recognizable bone features to establish anatomical reference points before procedures. In surgical planning, these points help relate the intended intervention to nearby bones and associated structures. For injections or other procedures, locating the appropriate landmark supports accurate placement by providing a surface-based guide to the targeted anatomical region.
