Final answer:
C) synapse Neurotransmitters transmit messages between neurons through the structure known as the synapse. This is where chemicals like dopamine play a pivotal role in neural communication.
Step-by-step explanation:
Neurotransmitters send chemical messages across the gap between one neuron and another in the synapse. The synapse is a specialised junction where a neuron can transmit a signal to another cell. This occurs when neurotransmitters are released from vesicles in an axon terminal, these molecules then travel across the synaptic gap and bind to receptors on the surface of the next neuron. The binding of neurotransmitters can induce a change in the receiving neuron, leading to the continuation of the nerve impulse. Dopamine is an example of a neurotransmitter that plays a role in the transmission of signals in the brain, affecting a variety of human behaviors and being involved in neurological disorders like Parkinson's disease and schizophrenia.
Neurotransmitters send chemical messages across the gap between one neuron and another in the synapse. The synapse is the space between the terminal button of one neuron and the dendrite of another neuron. It is where the neurotransmitter molecules are released and bind to receptors on the dendrites of the postsynaptic neuron, causing activation in the postsynaptic cell. This process allows for communication between neurons in the central nervous system.
