Question

dendrites:
a conduct action potentials away from the cell body
b contain the trigger zone
c form synapses with the microglia
d are generally long and unbranched
e are the input part of the neuron

Explanation:

• Dendrites receive signals from other neurons, making them the input part of the neuron.
• Option A: Axons conduct action potentials away from the cell body, not dendrites.
• Option B: The trigger zone is at the axon hillock, not in dendrites.
• Option C: Dendrites form synapses with other neurons (not microglia, which are glial cells for immune - related functions in the nervous system).
• Option D: Dendrites are generally short and branched.

Answer:

E. are the input part of the neuron
