Dendrites

Question

Dendrites
A) are the input part of the neuron.
B) conduct action potentials away from the cell body.
C) are generally long and unbranched.
D) form synapses with the microglia.
E) contain the trigger zone.

Accepted Answer

Dendrites are the input part of the neuron, receiving signals from other neurons and relaying them towards the cell body. Option B is incorrect because it is the axon that conducts action potentials away from the cell body. Option C is incorrect because dendrites are typically shorter and more branched than axons. Option D is incorrect because synapses are formed between dendrites and the terminal buttons of other neurons, not microglia. Option E is incorrect because the trigger zone is located at the junction between the axon hillock and the initial segment of the axon, not the dendrites.
