Neuroanatomy

Whick of the following analogies best describes the functional relationship between two different parts of a neuron?

• A dendrite is to an axon terminal, as presynaptic input signaling is to postsynaptic output
• A cell body is to a dendrite, as synaptic output is to synaptic integration
• A cell body is to synaptic output, as an axon is to action potential conduction
• A dendrite is to neurotransmitter release, as an axon terminal is to postsynaptic membrane neurotransmitter receptors
