Difference Between Presynaptic Neuron and Postsynaptic Neuron
1. What are the functions of presynaptic and postsynaptic neurons?
The function of the presynaptic neuron is to transmit messages to the synaptic cleft by releasing neurotransmitters. On the other hand, the postsynaptic neuron receives messages by taking up neurotransmitters from the synaptic cleft during nerve impulse transmission.
2. What is the location of a presynaptic neuron compared to a postsynaptic neuron?
The presynaptic neuron occurs before the synaptic cleft, while the postsynaptic neuron occurs after the synaptic cleft.
3. How do presynaptic and postsynaptic neurons affect calcium channels during transmission?
In the presynaptic neuron, the opening of calcium channels occurs upon depolarization, facilitating the release of neurotransmitters. In contrast, the postsynaptic neuron experiences the closing of calcium channels upon binding of neurotransmitters during the reception process.
4. What process is involved in transmitting messages in a presynaptic neuron?
The presynaptic neuron employs exocytosis, where synaptic vesicles fuse with the presynaptic membrane, releasing neurotransmitters into the synaptic cleft.
5. How does a postsynaptic neuron receive messages from the synaptic cleft?
The postsynaptic neuron utilizes endocytosis to take up neurotransmitters from the synaptic cleft, leading to depolarization and nerve impulse transmission.
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.
