Answer 1

Neuronal signals are transferred electrically within a neuron and chemically between neurons via synapses, where neurotransmitters bridge the gap and trigger an electrical response in the adjacent neuron.

Step-by-step explanation:

The question is about how signals are transferred from one neuron to another, which is a fundamental concept in neurobiology. In the nervous system, communication between neurons occurs at specialized junctions called synapses. A signal within a neuron is transferred electrically along the axon of the sending neuron towards the synapse. When the electrical signal reaches the end of the axon, it triggers the release of chemical messengers known as neurotransmitters from vesicles. These neurotransmitters cross the synaptic gap and bind to receptors on the membrane of the receiving neuron. This binding causes a change in the permeability of the receiving neuron's membrane, which can initiate an electrical signal within the receiving neuron, thus propagating the information.
