Which statements describe the function of the central nervous system synapse?

Question

Standard Text: Select all that apply.
1. Suppression, or inhibition, of the firing of neurons
2. Inhibition of the release of a neurotransmitter
3. Release of an inhibitory neurotransmitter that suppresses conduction
4. Simulation, or activation, of the firing of neurons
5. Serving as the primary functioning cell within the nervous system

Answer 1

Correct Answer: 1,2,3,4
Rationale 1: In some cases, the firing of neurons is inhibited.
Rationale 2: Synapses within the CNS operate by an electrical impulse releasing a neurotransmitter to activate a receptor neuron on the opposite side. In some cases, the electrical impulse inhibits the release of the neurotransmitter.
Rationale 3: In some cases, there is release of an inhibitory neurotransmitter that suppresses neuronal conduction.
Rationale 4: The neuron is the primary functional cell for communicating messages through conduction of an action potential.
Rationale 5: The neuron is the primary functioning cell within the nervous system.
Global Rationale: In some cases, the firing of neurons is inhibited. Synapses within the CNS operate by an electrical impulse releasing a neurotransmitter to activate a receptor neuron on the opposite side. In some cases, the electrical impulse inhibits the release of the neurotransmitter. In some cases, there is release of an inhibitory neurotransmitter that suppresses neuronal conduction. The neuron is the primary functional cell for communicating messages through conduction of an action potential. The neuron is the primary functioning cell within the nervous system.
