What's the difference between bipennate and fibre?
Bipennate
Definition:
(a.) Alt. of Bipennated
Example Sentences:
(1) Relationships between length and active force (at full activation) of the lower-leg muscles were calculated by use of (i) a unipennate muscle model, (ii) a bipennate model, and (iii) bipennate models in which the cosine of the pennation angle is approximated as length independent.
(2) The biceps femoris, a bipennate non-postural muscle, grew relatively faster in terms of wet and dry weight than did the parallel-fibred adductor superficialis or the unipennate adductor profundus, both postural muscles.
(3) The muscles used in this study fall into four morphologic categories: fusiform, unipennate, bipennate, and multipennate.
(4) Specimens of fusiform, unipennate, and bipennate muscles were pulled from their proximal as well as distal attachments.
(5) According to these measurements, and electromyographic findings by other authors, both muscles can be regarded as a bipennate muscle from a functional point of view.
(6) The model can predict the shape of the muscle fibres and tendinous sheets as well as the internal pressure distribution in the central longitudinal plane (perpendicular to the tendinous sheets) of uni- and bipennate muscle bellies.
(7) Our hypotheses were that (1) latissimus dorsi (LTD) muscles transplanted into the site of a bipennate rectus femoris (RFM) muscle with neurovascular repair would retain their parallel-fibered structure and (2) the parallel-fibered structure of latissimus dorsi grafts would reduce their total fiber cross-sectional area and adversely affect force development relative to that of bipennate rectus femoris grafts and muscles.
(8) The planar models predict a too low volume fraction for the muscle fibres (about 45% for the bipennate models with a straight central aponeurosis, and about 60% for the simulated unipennate muscle).
Fibre
Definition:
(n.) One of the delicate, threadlike portions of which the tissues of plants and animals are in part constituted; as, the fiber of flax or of muscle.
(n.) Any fine, slender thread, or threadlike substance; as, a fiber of spun glass; especially, one of the slender rootlets of a plant.
(n.) Sinew; strength; toughness; as, a man of real fiber.
(n.) A general name for the raw material, such as cotton, flax, hemp, etc., used in textile manufactures.
Example Sentences:
(1) During the performance of propulsive waves of the oesophagus the implanted vagus nerve caused clonic to tetanic contractions of the sternohyoid muscle, thus proving the oesophagomotor genesis of the reinnervating nerve fibres.
(2) The dependence of fluorescence polarization of stained nerve fibres on the angle between the fibre axis and electrical vector of exciting light (azimuth characteristics) has been considered.
(3) The variation of the activity of the peptidase with pH in the presence of various inhibitors was investigated in both control and insulted muscle fibres.
(4) Peptides from this region bind to actin, act as mixed inhibitors of the actin-stimulated S1 Mg2(+)-ATPase, and influence the contractile force developed in skinned fibres, whereas peptides flanking this sequence are without effect in our test systems.
(5) The myofibrils composed 60%, 70% and 83% in the same fibres.
(6) Immunogold electron microscopy demonstrated that outer dense fibres were the predominant immunoreactive site.
(7) Subthreshold concentrations of the drug to induce complete blockade (5 x 10(-8)M) allowed to observe a greater depression of bioelectric cell characteristics in primary than in transitional fibres.
(8) Somatostatin-like immunoreactivity has been found to occur in nerve terminals and fibres of the normal human skin using immunohistochemistry.
(9) The effect of dietary fibre digestion in the human gut on its ability to alter bowel habit and impair mineral absorption has been investigated using the technique of metablic balance.
(10) Acetylcholine (ACh) induces a K+ current in rabbit cardiac Purkinje fibres.
(11) At the light-microscopic level, adrenergic fibres were identified due to their formaldehyde-induced fluorescence.
(12) From these results, it can be suspected that the motor fibres are more vulnerable during aging.
(13) Most often, constrictor fibres follow the course of the pterygo-palatine nerve, when dilator fibres follow the infraorbital nerve.
(14) Striated muscle fibres were found in each of twenty consecutive pineal glands cultured from individual neonatal rats.2.
(15) Whereas the tight junctions of endoneurial capillaries are known to prevent certain blood-borne substances from entering the endoneurium, it was not clear whether the permeability of the pulpal capillaries, which are distant from the nerve fibres, could affect the nerve fibre environment.
(16) The percentage of energy from fat and added sugars and the amount of sodium and fibre in the diet tended to increase with energy intake.
(17) Actin is present in chromosomal spindle fibres, with consistent polarity.
(18) Ranges of V0 in the three fast fibre types mostly overlapped.
(19) Accumulations of filaments in the axons and in the perineural cells were accompanied by Rosenthal fibres.
(20) A new method of staining the keratin filament matrix allowing a visualization of the filaments in cross section of hair fibres has been developed.
