What Can We Learn from Single Sarcomere and Myofibril Preparations?
Frontiers in Physiology, 2022 Sarcomeres are the smallest functional contractile unit of muscle, and myofibrils are striated muscle organelles that are comprised of sarcomeres that are strictly aligned in series.

In vivo Sarcomere Lengths and Sarcomere Elongations Are Not Uniform across an Intact Muscle [PDF]
Frontiers in Physiology, 2016 Sarcomere lengths have been a crucial outcome measure for understanding and explaining basic muscle properties and muscle function. Sarcomere lengths for a given muscle are typically measured at a single spot, often in the mid-belly of the muscle, and at a given muscle length.

CONTRACTILE PROTEIN NUMBER IN ADJACENT SARCOMERES – IS THERE A DIFFERENCE? [PDF]
, 2014 INTRODUCTION Variation in sarcomere length within an actively contracting skeletal muscle has often been observed yet remains unexplained. Sarcomeres within a myofibril are connected in series and thus they must each produce the same amount of force [1].

The force of the myosin motor sets cooperativity in thin filament activation of skeletal muscles
Communications Biology, 2022 Sarcomeres of Ca2 + -activated demembranated fibres of rabbit soleus muscles show that the stress exerted by each motor protein on the thin filament determines the cooperativity in thin filament activation.

Force–length relation of skeletal muscles: from sarcomeres to myofibril [PDF]
, 2018 Sarcomeres are building blocks of skeletal muscles. Given force–length relations of sarcomeres serially connected in a myofibril, the myofibril force–length relation can be uniquely determined.

Titin-dependent biomechanical feedback tailors sarcomeres to specialized muscle functions in insects [PDF]
Sarcomeres are the universal contractile units of muscles that enable animals to move. Insect muscles display a remarkable functional diversity: they operate at extremely different contraction frequencies (ranging from ~1 to 1000 hertz) and amplitudes ...

Myofibril Changes in the Copepod Pseudodiaptomus marinus Exposed to Haline and Thermal Stresses. [PDF]
PLoS ONE, 2016 Copepods are small crustaceans capable to survive in various aquatic environments. Their responses to changes in different external factors such as salinity and temperature can be observed at different integration levels from copepod genes to copepod ...
