Presynaptic neurons release the neurotransmitter in response to an action potential. Postsynaptic neurons receive the neurotransmitter (and can however become presynaptic to the next nerve cell, if the neurotransmitter has stimulated the cell enough).

What is the difference between presynaptic and postsynaptic neurons in the context of synaptic transmission?

Presynaptic neurons send signals, while postsynaptic neurons receive signals in synaptic transmission. Presynaptic neurons release neurotransmitters that travel across the synapse to bind to receptors on postsynaptic neurons, triggering a response.


When two neurons are separated by a synapse which two parts of the neurons meet?

In a synapse, the terminal of the presynaptic neuron and the dendrite or cell body of the postsynaptic neuron meet. The presynaptic neuron releases neurotransmitters into the synaptic cleft, where they bind to receptors on the postsynaptic neuron, allowing for communication between the two neurons.


When two or more presynaptic neurons synapse with a single postsynaptic neuron in the CNS what pathway is formed?

When two or more presynaptic neurons synapse with a single postsynaptic neuron in the central nervous system (CNS), it forms a convergent pathway. This allows for integration of multiple inputs onto a single neuron, influencing the postsynaptic neuron's response.


When nerve impulses from several presynaptic neurons stimulate a single postsynaptic neuron at the same time it is called?

chemical synapse


Can a synapse connect more than 2 neurons?

No, a synapse is a specialized junction between two neurons where communication occurs through the release of neurotransmitters. Each synapse allows for communication between one presynaptic neuron and one postsynaptic neuron.


What is the space between neurons across which chemical messages pass?

The space between neurons is called the synaptic cleft. It is where neurotransmitters are released by the presynaptic neuron, travel across the cleft, and bind to receptors on the postsynaptic neuron to transmit chemical messages.


What is The process of adding the effects of many postsynaptic potentials?

The process of adding the effects of many postsynaptic potentials is called summation. There are two types of summation: temporal summation, where postsynaptic potentials from the same presynaptic neuron add up over a short period of time, and spatial summation, where postsynaptic potentials from multiple presynaptic neurons add up at the same time. Summation ultimately determines whether an action potential will be generated in the postsynaptic neuron.


What are the synaptic events?

Synaptic events refer to the processes involved in communication between neurons at synapses. These events include neurotransmitter release from the presynaptic neuron, binding of neurotransmitters to receptors on the postsynaptic neuron, and subsequent changes in the postsynaptic neuron's membrane potential. This can lead to excitation or inhibition of the postsynaptic neuron based on the type of neurotransmitter and receptors involved.


A synapse consist of?

A synapse is the connection between two neurons. It consists of the synaptic cleft (the physical gap between one neuron's axon and the other's dendrite). Neurotransmitters cross the gap from the axon to the dendrite and affect whether the next neuron fires.


What is a synapse and how is information transmitted at the synapse?

A synapse is a structure that allows communication between neurons. Information is transmitted across the synapse through the release of neurotransmitters from the presynaptic neuron, which then bind to receptors on the postsynaptic neuron, leading to changes in the postsynaptic neuron's electrical activity.


What is an event when one or more presynaptic neurons fire in rapid order it produces a much greater depolarization of the postsynaptic membrane than would result from a single ESPS?

This is known as temporal summation, where multiple action potentials from presynaptic neurons arrive in quick succession at a synapse, leading to an accumulation of excitatory postsynaptic potentials (EPSPs) that can reach the threshold for generating an action potential in the postsynaptic neuron. This process enhances synaptic transmission and the strength of the signal being transmitted.


Describe the structure of a synapse?

The synapse consists of two main parts that allow one neuron to communicate with another: 1) the presynaptic terminal located at the end of an axon; and 2) the postsynaptic terminal located on the dendrite of another neuron. The presynaptic terminal is where neurotransmitters are stored and released from. The postsynaptic terminal is the recipient side of the synapse. Neurotransmitters released from the presynaptic terminal will diffuse across the synaptic cleft and bind to receptors located on the surface of dendritic spines.
