Is there sufficient evidence to claim muscle units are not localised and functionally grouped within the human gastrocnemius?

it is not possible to understand developments of a country’s culture and civilization without knowing his believes and myths. whether it is north or south, east or west, planes or mountains, sahara or deserts, here in iran every corner includes valuable and precious treasures which are known all over the world, and cultural – historical objects which are found here adorn all well known museums of the globe. zagros mountains, lorestan province locating at the heart of that, are not only the same, but are more prominent than other iranian regions. you can not find someone who does not know what the lorestani bronzes are, and there is no museum that not be pride of having a piece of that. the said bronzes which are manufactured four millenniums b.c. are admired nearly by all those researchers because of their beauty, diversity and technique. lorestani artistic works including stone engraves, bronzes and clays, show an ideal and metaphysical world beside real world which explain mental system of human beings on that era against sensations and phenomena happening around them. men main mental occupation on that time was he unknown world which had surrounded them, and they used to use the religion to fight life’s natural factors, and art was a tool of religious and mythical painting which was far from reality and had entered into the abstract domain. as natural objects have become subjects of lorestani art, it cleanses them from any non – intrinsic limitations and external factors which surround them and darken their meanings, and just shows their main specifications. artist in the said civilization is not searching for realism. although these are few works showing the nature, but in effect there is no wish to imitate touchable factors of the nature, and artist has turned real phenomena to encoded signs as per his own mentality. this procedure is called stylization.

Passive mechanical properties of human gastrocnemius muscle-tendon units
Background The passive mechanical properties of skeletal muscletendon units are important because they determine the amount of motion available at joints. Human gastrocnemius muscle-tendon units are of particular interest because this muscle is prone to develop contractures, may have a role in lower limb overuse injuries, and is a common site of muscle tears. This workshop provides an introduct...
متن کاملGlycogen synthesis in human gastrocnemius muscle is not representative of whole-body muscle glycogen synthesis.
The introduction of 13C magnetic resonance spectroscopy (MRS) has enabled noninvasive measurement of muscle glycogen synthesis in humans. Conclusions based on measurements by the MRS technique assume that glucose metabolism in gastrocnemius muscle is representative for all skeletal muscles and thus can be extrapolated to whole-body muscle glucose metabolism. An alternative method to assess whol...
متن کاملPassive mechanical properties of human gastrocnemius muscle tendon units, muscle fascicles and tendons in vivo.
This study provides the first in vivo measures of the passive length-tension properties of relaxed human muscle fascicles and their tendons. A new method was used to derive passive length-tension properties of human gastrocnemius muscle-tendon units from measures of ankle stiffness obtained at a range of knee angles. Passive length-tension curves of the muscle-tendon unit were then combined wit...
متن کاملRecruitment of motor units in the medial gastrocnemius muscle during human quiet standing: is recruitment intermittent? What triggers recruitment?
The recruitment and the rate of discharge of motor units are determinants of muscle force. Within a motoneuron pool, recruitment and rate coding of individual motor units might be controlled independently, depending on the circumstances. In this study, we tested whether, during human quiet standing, the force of the medial gastrocnemius (MG) muscle is predominantly controlled by recruitment or ...
