A neurotransmitter released onto a motor neuron opens a Cl- channel. This typically causes:

A. An IPSP
B. An EPSP
C. A MEPP
D. An action potential
E. An EPP

Answer :

Final answer:

The release of a neurotransmitter onto a motor neuron can cause an inhibitory postsynaptic potential (IPSP) by opening a Cl- channel.

Explanation:

Neurotransmitters, such as acetylcholine (ACh), are released by motor neurons and bind to receptors on the motor end plate. When ACh binds to the receptors, ion channels, such as sodium channels, open and allow the passage of ions into the muscle cell. In this case, the opening of a Cl- channel by the neurotransmitter leads to a hyperpolarization of the cell membrane, called an inhibitory postsynaptic potential (IPSP).
