The endocrine system communicates using which signals?

The endocrine system communicates using which signals?

• A. Nerves
• B. Hormones
• C. Neurons
• D. Synapses

Answer: (B)

Endocrine signaling uses hormones as chemical messengers that travel through the bloodstream to distant target cells, producing slower, longer-lasting effects on processes like metabolism and growth. This contrasts with the nervous system, which sends rapid electrical impulses along nerves and uses neurotransmitters at synapses for quick, local responses. Synapses are the junctions where neurons communicate, not the bloodstream-based communication of the endocrine system. So the signals of the endocrine system are hormones.
