Difference Between Presynaptic Neuron and Postsynaptic Neuron
Here’s the Tabular Difference between Presynaptic Neuron and Postsynaptic Neuron with their definition, location, functions, effects etc.
Features |
Presynaptic Neuron |
Postsynaptic Neuron |
---|---|---|
Definition |
The presynaptic neuron is the neuron that is involved in transmitting the message to the synaptic cleft by releasing neurotransmitters |
The postsynaptic neuron is the neuron that is involved in receiving the message by taking up the neurotransmitters from the synaptic cleft during nerve impulse transmission. |
Location | Occurs before synaptic cleft | Occurs after synaptic cleft |
Function | Sends Information | Receives Information |
Effects | Opening of calcium channels | Closing of calcium channels |
Result |
The nerve impulse is transmitted to the synapse | The nerve impulse is transmitted from the synapse to another neuron. |
Process Involved | Exocytosis | Endocytosis |
Type of knobs that mediate transmission | Presynaptic knobs | Postsynaptic receptors |
Difference Between Presynaptic Neuron and Postsynaptic Neuron
Difference Between Presynaptic Neurons and Postsynaptic Neurons: Presynaptic Neurons and Postsynaptic Neurons are two neurons that are involved in forming chemical synapses for the transmission of impulses between two neurons. The major difference between a presynaptic neuron and a postsynaptic neuron is that the presynaptic neuron is involved in transmitting a message to the synaptic cleft by releasing neurotransmitters while the postsynaptic neuron is involved in receiving the message from the synaptic cleft by taking up neurotransmitters from the cleft.
In this article, you will study the Difference between Presynaptic Neuron and Postsynaptic Neuron, along with their similarities.
