Which Factors Make Propagation of Electrical Signals in Dendrites More

question 55

Multiple Choice

Which factors make propagation of electrical signals in dendrites more complex than in axons?

• A) The membrane capacitance of dendrites differs from that of neurons.
• B) Dendrites do not express voltage-gated ion channels.
• C) Dendrites contain a wide variety of voltage-gated ion channels and different branches have different input resistance, which varies with the activity of excitatory and inhibitory synapses.
• D) Dendrites do not receive excitatory and inhibitory synaptic inputs.
• E) Dendrites typically have smaller input resistance than axons, which prevents efficient propagation of electrical signals.
