Birefringence and force produced by pig tracheal smooth muscles were recorded every 100 ms during electrically stimulated tetani at muscle lengths that varied 1.5-fold and at the peak of acetylcholine contractures at the same lengths. Isometric force

A method is described for freezing thin strips of smooth muscle by replacing physiological saline in the muscle chamber with cold organic solvent in100 ms. Calculations suggest that, with a perfectly stirred boundary at the tissue surface, freezing c

To better understand excitation-contraction coupling in smooth muscle, myosin phosphorylation and force-velocity properties of canine tracheal muscle were compared during the rise and early plateau of force in electrically stimulated tetani. Velocity

A force transducer with variable sensitivity and speed is described. Its moving element is a cantilever beam that projects vertically into a muscle bath. A brace constrains bending of the beam to a short, proximal “hinge.” Rotation of the beam ab

To assess activation mechanisms of dog trachealis muscle and test whether isometric force generation could be separated from myosin light-chain (MLC) phosphorylation, force and phosphorylation were measured in the presence of wortmannin (a light-chai
