(17) These data indicate that magnesium ions: 1) bring about vasodilatation without releasing adrenergic amines, histamine, serotonin, acetylcholine, prostaglandins, or endogenous opioids; 2) are direct, potent vasodilators of intact rat cremaster muscle microvessels; 3) may have a depressive action on heart; 4) exert these microvascular and cardiac actions in low doses and 5) can produce severe hypotension and bradycardia only after i.v.
(18) The influence of flow patterns and erythrocyte concentration on the post-junctional radial position of leukocytes was studied in microvascular junctions in an isolated mesocaecum preparation and in vivo in the rat cremaster muscle.

(20) Studies were made on whether substance P-, leucine-enkephalin- and 5-hydroxytryptamine (serotonin)-like immunoreactive fibers exert a direct influence on the cremaster motoneurons of the male rat by immunocytochemistry combined with retrograde tracing at the light- and electron-microscopic levels.
Muscle
Definition:
(n.) An organ which, by its contraction, produces motion.
(n.) The contractile tissue of which muscles are largely made up.
(n.) Muscular strength or development; as, to show one's muscle by lifting a heavy weight.
(n.) See Mussel.
Example Sentences:
(1) The extents of phospholipid hydrolysis were relatively low in brain homogenates, synaptic plasma membranes and heart ventricular muscle.
(2) It was found that the skeletal muscle enzyme of the chick embryo is independent of the presence of creatine and consequently is another constitutive enzyme like the creatine kinase of the early embryonic chick heart.
(3) These immunocytochemical studies clearly demonstrated that cells encountered within the fibrous intimal thickening in the vein graft were inevitably smooth muscle cell in origin.
(4) We have amended and added to Fabian's tables giving a functional assessment of individual masticatory muscles.
(5) 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.
(6) Muscle weakness and atrophy were most marked in the distal parts of the legs, especially in the gastrocnemius and soleus muscles, and then spread to the thighs and gluteal muscles.
(7) No monosynaptic connexions were found between anterodorsal and posteroventral muscles except between the muscles innervated by the peroneal and the tibial nerve.
(8) Thus adrenaline, via pre- and post-junctional adrenoceptors, may contribute to enhanced vascular smooth muscle contraction, which most likely is sensitized by the elevated intracellular calcium concentration.
(9) In addition to their involvement in thrombosis, activated platelets release growth factors, most notably a platelet-derived growth factor (PDGF) which may be the principal mediator of smooth muscle cell migration from the media into the intima and of smooth muscle cell proliferation in the intima as well as of vasoconstriction.
(10) Further, the maximal increase in force of contraction was measured using papillary muscle strips from some of these patients.
(11) Peripheral eosinocytes increased by 10%, and tests for HBsAg, antiHBs, antimitochondrial antibody and anti-smooth muscle antibody were all negative.
