Detailed explanation-1: -The minimum stimulus needed to achieve an action potential is called the threshold stimulus.
Detailed explanation-2: -Threshold: the level of stimulation required to trigger a neural impulse. Synapse: the junction between the terminal branch of the synaptic gap. Synaptic gap/synaptic cleft: the tiny gap at the synapse in which neurotransmitters cross.
Detailed explanation-3: -The minimum level of stimulation required to trigger a neural impulse is called the: threshold.
Detailed explanation-4: -The MINIMUM LEVEL of a STIMULUS that is REQUIRED to Activate a neuron is called the THRESHOLD.
Detailed explanation-5: -A nerve impulse begins when a neuron receives a chemical stimulus. The nerve impulse travels down the axon membrane as an electrical action potential to the axon terminal. The axon terminal releases neurotransmitters that ca rry the nerve impulse to the next cell.
