Answer #1

Answer

Option A) Dendrites and their receptors

  • A synapse is made up of three components :
    - Presynaptic membrane
    - Synaptic cleft
    - Postsynaptic membrane
  • Presynaptic membrane is the axon terminal that releases neurotranmsitter into the synaptc cleft to transmit the signal.
  • Postsynaptic membrane is dendrites that contain receptors for neurotransmitter. As neurotransmitter binds to its receptors, the chemical signal is changed into electrical impulses that are forwarded to the soma / cell body.
