Activation of M₁, M₃, or M₅ receptors leads to _______ of the _______ cell, while activation of M₂ or M₄ receptors leads _______of the _______ cell.

Question

Quizplus · Accepted Answer

The correct answer involves understanding that the activation of certain receptors leads to excitation or inhibition of the cell, and the distinction between effects on presynaptic versus postsynaptic cells. The question format suggests a focus on the postsynaptic cell's response to receptor activation, with some receptors causing excitation or inhibition and others affecting the cell differently. Thus, option D correctly identifies that activation of the first set of receptors results in excitation or inhibition of the postsynaptic cell, while the second set of receptors also targets the postsynaptic cell but with the opposite effect.

Activation of M1, M3, or M5 Receptors Leads to _______

Activation of M₁, M₃, or M₅ Receptors Leads to _______
