Unlike neurotransmitters, hormones travel through the bloodstream to reach their target cells.

검증된 단계별 안내1
Understand the role of signaling molecules: Both hormones and neurotransmitters are crucial for communication within the body, but they operate in different systems.
Identify the pathways: Neurotransmitters are released from neurons and travel across synapses to reach nearby target cells, while hormones are secreted by glands and travel through the bloodstream to reach distant target cells.
Consider the types of molecules: Neurotransmitters are typically small molecules or peptides, whereas hormones can be peptides, steroids, or even amino acid derivatives.
Evaluate the number of molecules: There are many different neurotransmitters and hormones, each with specific functions, contrary to the statement that there are only 2 neurotransmitters.
Conclude with the key difference: The primary distinction is that neurotransmitters act locally at synapses, while hormones have a broader range of action through the circulatory system.
