Question

When an _________ message reaches the dendrites of a neuron, the cell becomes more negative and the likelihood that a nerve impulse will occur is _________________.

Answer 1

1. Inhibitory message

2. decreased

Step-by-step explanation:

The transmission of the nerve impulse through the neurons is passed on to the next neuron at the synapse. At the synapse, one neuron contact to another neuron in the form of chemical signals as neurotransmitters.

These neurotransmitters can excitatory neurotransmitter or they can be inhibitory transmitter which depends on the message of the stimulus.

If the inhibitory neurotransmitter is released, it then inhibits the action potential by changing the resting membrane potential towards the more negative side. As a result of this, the action potential is not generated in the postsynaptic neuron.

Thus, Inhibitory message and decreased is correct.
