So, how do muscles contract? The functional units of muscle fibers are calledsarcomeres. When viewed under the microscope skeletal muscle has a striped pattern. This is because of the molecular structure of the sarcomere. Muscles are made of thousands of sarcomeres stacked on top of each other...

A new molecular model is proposed for muscle contraction, that involves the electrical charging of the long (C-terminal) alpha-helical part of the head of the myosin molecule (S1) while the head is attached to actin; as it charges the alpha-helical part moves in the radial electric field...
How muscle repairs itself Repair is our body’s other healing system. The repair system doesn’t generate new tissue, but instead, it grows scar tissue to patch up injuries that are too large for us to fix with new cells of the original type. During repair, your body sends collagen to...
The airways that bring air into the lungs (the trachea and bronchi) are made of smooth muscle and cartilage, allowing the airways to constrict and expand. The lungs and airways bring in fresh, oxygen-enriched air and get rid of waste carbon dioxide made by your cells. They also help in ...
Muscle works harder than fat, and calories are used to activate, contract and repair your muscles after use. Most forms of resistance exercise will increase your calorie expenditure, even in the hours post exercise. In one study, researchers found that regular weight training boosts basal ...
Rope jumping is a whole-body workout that recruits more muscle groups than running. While running recruits the hamstrings, calves, quads, and glutes, rope jumping also works your abs and obliques as you twist and turn to keep the ropes going. Additionally, there are many other muscles used...
That unbroken surface, however, is also super-easy to clean. As you might expect with any stove swap, it takes some time to adjust muscle memory for one range’s output for another’s, which can be a issue for particularly temperature-sensitive recipes. The embedded electronics in an ...
How does the cardiac muscle cell work with other cells/ tissues/ organs to achieve its function? What are main parts of the circulatory system and their functions? Explain what homeostasis is and why it is so important to the proper function of the human body. What are the th...
In vitro disease models have been used as another alternative for human disease models since the discovery of induced pluripotent stem cells (iPSCs). Human cardiomyocytes have been generated from patient-derived iPSCs, which are genetically identical to the derived patients. Researchers have attempted...
