Module 7: Figure bladder pacemaker acceleration

Carbachol accelerates electrical and contractile activity of guinea-pig bladder.

The rhythmical action potentials (trace a) and contractions (trace b) of guinea-pig bladder were markedly accelerated by a low dose of carbachol. Note the tonic contraction that develops slowly during the action of carbachol. Reproduced from Hashitani et al (2004).
