Novel microstructural findings in M. plantaris and their impact during active and passive loading at the macro level.

摘要: There are several studies dealing with experimental and structural analyses of skeletal muscles that aimed at gaining a better understanding three-dimensional muscle deformation force generation. A variety these contributions have performed or mechanical analyses, but very few combined approaches different levels. To fill this gap, the present study aims to bring together micro-structural findings in rabbit M. plantaris load transfer mechanisms inside during passive loading active contraction. During two states, surface aponeurosis-tendon complex was recorded using optical measurement systems. In way, strain distribution on can be calculated interpret muscle. The results show activation is completely from loading. Under both conditions, irregular. findings, gross try fascicle architecture were determined. doing so, highly microstructure featuring tube- sail-like structure identified. Moreover, compartmentalisation into compartments detected. smaller, bipennated compartment embedded larger, unipennated compartment. authors' knowledge, type inner has never been previously documented single-headed muscles.
