Muscle this consists of bundles of muscle fibers separated and held together by fibrous walls called fascia.
In some muscles the fascia to join the bone becomes tendon.
The fibers are formed by myofibrils and these in turn by the macromere, and macromere composed of acting and myosin.
Inside the fiber there is a structure called the muscle spindle and nerve fibers arrive there two types:
Tonics: The brain emits stimuli to the muscle and allows the muscle activity in a particular individual function (contraction, postural, stretching …)
Sensitive: spindle will provide information to the brain and the state of the muscle and joints.
GRP motor nerve fiber that goes directly into the muscle structure (not the spindle).
Endplate: Via part of the central nervous system and reaches the functional unit of muscle contraction providing the power.
Set tonic-physic: Tonic (postural muscles) physic (dynamic muscle)
Set-rhythmic tonic.
Continuous: repetitive work without increasing the load (domestic, academic work)
Rhythmic: physical activity, up work elasticity.
Functionality and Positioning:
Cardiovascular endurance
Muscular
Strength
Flexibility
Speed
Coordination.
Postural muscles: deep longitudinal muscles, muscles that must be prepared for everyday burdens and if they were not has to take a training course in order to be able to counteract the daily aggression.
Muscle function: It is more superficial and usually cross (trapeziums, altissimo, pecks, oblique, back …) if the postural muscles gave the functional takes over the position is not without paying tribute to the contracture or clamping disk.
Longitudinal continuous tonic postural Deep.
Physic Titmice cross functional surface
