Question

Quizplus · Accepted Answer

Neurotransmitters are chemical messengers that transmit the neural signal across synapses to other neurons. Ion channels are membrane proteins that allow the passage of ions, but they do not transmit signals between neurons. Action potentials are electrical signals that propagate along the axon of a neuron, but they do not cross the synaptic cleft. Hormones are chemical messengers that are secreted by endocrine glands and travel through the bloodstream to target cells, but they are not involved in transmitting signals between neurons.
