Questions and Answers
What role do dendrites play in the neuron?
What role do dendrites play in the neuron?
- They transmit messages from the soma to the axon.
- They receive chemical messages from neurotransmitters. (correct)
- They interpret the message sent by the neurotransmitters.
- They convert chemical messages into electrical signals.
How does the soma process the message received from dendrites?
How does the soma process the message received from dendrites?
- It enhances the chemical message before passing it on.
- It decodes the message and forwards it to the axon. (correct)
- It converts the message into heat energy.
- It ignores irrelevant messages completely.
What happens to the message once it reaches the axon?
What happens to the message once it reaches the axon?
- It is stored for future use.
- It is transmitted back to the soma for reevaluation.
- It is transformed into a chemical message.
- It is transformed into an electrical impulse. (correct)

Study Notes
Neuron Functionality
- Neurotransmitters act as chemical messengers that convey signals between neurons.
- Dendrites are specialized structures that receive incoming neurotransmitter signals and transmit this information to the soma.
- The soma processes the received message, determining its significance before forwarding it to the axon.
- The axon plays a crucial role in converting chemical signals from the soma into electrical impulses, facilitating communication along the neuron.
- The speed of signal transmission through the axon can vary based on the urgency of the message, with more important signals traveling faster to the axon hillock.
