Question

what is the order that a message travels from one neuron to another? a. messages travel from the dendrites through the cell body and down the axon to the axon terminals. the message is then sent across the synapse by means of neurotransmitters to the dendrites of the next neuron, and so on. b. the message is then sent across the synapse by means of neurotransmitters to the dendrites through the cell body and down the axon to the axon terminals. c. the message travels across the synapse by means of neurotransmitters to the dendrites of the next neuron, and down the axon terminals. d. messages travel through the cell body and down the dendrites to the axon terminals. the message is then sent to the dendrites of the next neuron, and so on. ∘ sentence c ∘ sentence d ∘ senence a ∘ sentence b

Explanation:

To determine the correct order of a message traveling between neurons, we recall the structure and function of a neuron: Dendrites receive signals, which then go through the cell body, down the axon to axon terminals. From there, neurotransmitters send the message across the synapse to the dendrites of the next neuron.

• Option A: Follows the correct path (dendrites → cell body → axon → axon terminals → synapse → next neuron's dendrites).
• Option B: Incorrectly orders the synapse transmission before the internal neuron path.
• Option C: Omits the internal neuron path (dendrites → cell body → axon) and has an incorrect flow.
• Option D: Incorrectly states the message travels through the cell body to dendrites (dendrites should receive first, not be a downstream path). Also, there's a typo "Senence A" which is likely a typo for "Sentence A", but the content of A is correct.

Answer:

A. Messages travel from the dendrites through the cell body and down the axon to the axon terminals. The message is then sent across the synapse by means of neurotransmitters to the dendrites of the next neuron, and so on. (Note: There is a typo in the option label as "Senence A" which should be "Sentence A", but the content of this option is correct.)
