Answer to Question 1

There are five main types of sympathetic (adrenergic) receptors: alpha1, alpha2, beta1, beta2, and dopamine (or dopaminergic).

Myocardial cells (working or mechanical cells) contain contractile filaments. When these cells are electrically stimulated, the contractile filaments slide together, and the myocardial cell contracts.
