Answer:
Neurotransmitter
Explanation:
A neurotransmitter is a signal which transmits information between neurons at the end of the axon. This neurotransmitter can either be excitatory or inhibitory. Whenever an action potential is triggered within a neuron, the neurotransmitter releases this action potential into the synapses at the axon as either an excitatory or inhibitory signal before a new action potential is triggered.
3A- Negative feedback occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances.
3B- Negative feedback loops are used to maintain homeostasis and achieve the set point within a system. Negative feedback loops are characterized by their ability to either increase or decrease a stimulus, inhibiting the ability of the stimulus to continue as it did prior to sensing of the receptor.
