Summary Introduction

To determine:

The effect of stimulation of muscarinic receptors in cardiac muscles of the heart.

Concept introduction:

Muscarinic receptors are one of the two acetylcholine receptors. They form a G-protein receptor complex in neural cell membrane and in some other cells also. Muscarinic receptors are such type of receptors that are found in the entire body. Their functions differ with their location and their subtypes. There are five types of muscarinic receptors ranging from ${\text{M}}_{\text{1}}{\text{to M}}_{\text{5}}\text{.}$
