alexa Muscle Contraction|OMICS International|Bioenergetics: Open Access

OMICS International organises 3000+ Global Conferenceseries Events every year across USA, Europe & Asia with support from 1000 more scientific societies and Publishes 700+ Open Access Journals which contains over 50000 eminent personalities, reputed scientists as editorial board members.

Muscle Contraction

The term Muscle contraction is defined as the stretching or relaxation of the muscle fibers. There are two kinds of Muscle contraction named voluntary and involuntary. Voluntary muscle contraction is controlled by the central nervous system. Involuntary muscle contraction is controlled by the innate or involuntary brain activity or stimuli. Two important proteins actin and myosin play vital role in the energy dependent function of the muscle. Action potential originating in CNS by calcium signaling releases acetylcholine this in turn drives the actin, myosin functions by ATP. Calcium binds to TroponinC present on the actin making it to unblocking the binding sites. Myosin binds to the unblocked binding sites on the thin filament of actin. The conversion of ADP to ATP results in the power stroke. Actin acts as a cofactor advancing the release. This results in dragging the Z-bands towards each other and shortening the I-band. Repetition of these cycles results in muscle contraction or release. Bioenergetics: Open Access is expecting an impact factor for its journal in upcoming years in the field of its excellence with the related and competitive journals in the field of chemistry, physiology and metabolic related disorders. Covering the boarder scope classifications of the journal to have articles on overall to get the impact factor for its journal at the earliest. OMICS Group is one such international publishing group having in its pocket, handful of journals with the expecting impact factor. Impact factor is very necessary for the journal to have good number of citations for the published articles per issue for every volume.
