Dendrites of the postsynaptic neurons are the structures that receive chemical messages -neurotransmitters- from the presynaptic neurons. The correct option is D. Dendrites.
<h3>What is a synapse?</h3>
Neurons are cells that communicate with each other through the transmition of nervous impulses.
Every neuron forms connections with other neurons or with effector organs, such as the muscle. These connections are known as synapses.
Synapses can be either chemical or electrical. The most common one is the chemical synapses that involve the release of a substance known as a neurotransmitter.
During chemical synapses, when a presynaptic neuron sends information, it releases neurotransmitters. This event is done through exocytosis.
The neurotransmitter is a molecule that travels through the synaptic space forward to the dendrites of the other neuron or to the effector cell. Once the chemical reaches the postsynaptic membrane, it binds to its receptors.
This binding neurotransmitter-receptor produces excitatory postsynaptic potential, which is the depolarization of the postsynaptic cell.
Once the action potential is initiated, it spreads to the rest of the membrane, depolarizing it.

According to this framework, when two neurons communicate, the neurotransmitter released by one of them reaches the receptors located in the dendrites of the postsynaptic cell.
Dendrites are the structures that receive chemical messages from the other cells.
The correct option is D. Dendrites.
