Answer;
- 100
Researchers have identified about 100 substances that are made in our body and brain that act as neurotransmitters.
Explanation;
-Neurotransmitters are the chemicals which allow the transmission of signals from one neuron to the next across synapses. They are also found at the axon endings of motor neurons, where they stimulate the muscle fibers.
-Neurotransmitters enable neurotransmission, which is the process by which signaling molecules (neurotransmitters) are released by the axon terminal of a neuron (the presynaptic neuron), and bind to and activate the receptors on the dendrites of another neuron.
