Multiple Choice

Why is it accurate to describe neural communication as an 'electrochemical process'?

Because it relies solely on electrical signals to transmit information across the synapse.

Because it involves electrical signals within neurons and chemical signals between neurons.

Because it depends on electrical signals to release neurotransmitters into the bloodstream.

Because it uses chemical signals to generate action potentials within neurons.

Verified step by step guidance

Understand that neural communication involves two main types of signals: electrical and chemical.

Recognize that electrical signals, known as action potentials, travel along the axon of a neuron. These are generated by the movement of ions across the neuron's membrane.

Identify that when an action potential reaches the end of an axon, it triggers the release of neurotransmitters, which are chemical signals.

Note that neurotransmitters cross the synapse, the gap between neurons, and bind to receptors on the next neuron, initiating a new electrical signal.

Conclude that neural communication is described as an 'electrochemical process' because it involves electrical signals within neurons and chemical signals between neurons.
