Neurons communicate by __________.
A
short-distance electrical signals
B
long-distance chemical signals
C
short-distance electrical signals and long-distance chemical signals
D
None of the listed responses is correct.
E
short-distance chemical signals and long-distance electrical signals
Verified step by step guidance1
Understand the basic structure and function of a neuron, which includes the cell body, dendrites, and axon. Neurons are specialized cells that transmit information throughout the nervous system.
Recognize that neurons communicate through both electrical and chemical signals. Electrical signals, known as action potentials, travel along the axon of a neuron.
Identify that the communication between neurons at synapses involves chemical signals. Neurotransmitters are released from the axon terminal of one neuron and bind to receptors on the dendrite of another neuron.
Clarify that short-distance communication within a neuron involves electrical signals, while long-distance communication between neurons involves chemical signals.
Conclude that the correct answer is that neurons communicate by short-distance electrical signals and long-distance chemical signals, as electrical signals travel within the neuron and chemical signals are used to communicate between neurons.
