Specific examples of this principle are presented in these lectures and throughout the course.

The adrenergic receptors which subserve the responses of the sympathetic nervous system have been divided into two discrete subtypes: alpha adrenergic ...

Beta blockers are either selective for the beta1 receptor or nonselective beta1 and beta2 antagonists.

Therefore, they selectively activate beta2 receptors when compared to beta1.
