question 75
usually nerve impulses travel from one neuron to another by:
a action potentials
b resting potentials
c neurotransmitters
d nodes of ranvier
e threshold potentials

Explanation:

To solve this, we analyze each option:

• Option A: Action potentials are electrical signals within a single neuron, not for transmission between neurons.
• Option B: Resting potentials are the electrical state of a neuron at rest, not for inter - neuron communication.
• Option C: Neurotransmitters are chemical messengers that are released from the presynaptic neuron and bind to receptors on the postsynaptic neuron, allowing the nerve impulse to travel from one neuron to another across the synapse.
• Option D: Nodes of Ranvier are gaps in the myelin sheath that help in the propagation of action potentials within a neuron, not for communication between neurons.
• Option E: Threshold potentials are the level of depolarization needed to trigger an action potential within a neuron, not for inter - neuron signal transfer.

Answer:

C. Neurotransmitters
