the four phases of temporal summation are : fatigue, incomplete tetanus, treppe & complete tentanus.
What else can I help you with?
A series of similar stimuli that increases change in local membrane potential is called?
Action potential
When the second excitory postsynaptic potential arrives at a single synapse before the effect of the first has disappeared what occurs?
Summation occurs, where the two excitatory postsynaptic potentials combine to reach the threshold for firing an action potential. This can be either temporal summation, where two EPSPs from the same presynaptic neuron occur in quick succession, or spatial summation, where EPSPs from different presynaptic neurons arrive simultaneously.
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 is the accumulation of multiple EPSPs on a postsynaptic cell is called?
The accumulation of multiple excitatory postsynaptic potentials (EPSPs) on a postsynaptic cell is called temporal or spatial summation. Temporal summation occurs when multiple EPSPs are generated in rapid succession at the same synapse, while spatial summation involves simultaneous EPSPs from multiple synapses. Together, these processes can lead to the depolarization of the postsynaptic membrane and potentially trigger an action potential if the threshold is reached.
When impulses from various sources have an additive effect on a neuron the process is called?
When impulses from various sources have an additive effect on a neuron, the process is called summation. This can occur through temporal summation, where multiple impulses from the same source rapidly fire in succession, or spatial summation, where impulses from different sources converge at the same time to reach the neuron's threshold for firing.
Can the firing of one neuron produce temporal summation?
True
Which type of summation is the result of numerous nerve impulses arriving at a synapse at closely timed intervals?
Temporal summation
What is temporal summation?
it's the effect of a singel neurone as a way of achieving action potentian
What is the phenomenon that enables frequently used synapses to transmit signals more easily?

How does temporal summation differ from spatial summation?
Temporal summation occurs when multiple excitatory postsynaptic potentials (EPSPs) are generated at the same synapse in rapid succession, leading to a greater overall depolarization of the postsynaptic neuron. In contrast, spatial summation involves the simultaneous activation of multiple synapses on a postsynaptic neuron, allowing the combined effect of EPSPs from different locations to reach the threshold for action potential generation. Both processes are crucial for integrating synaptic inputs, but they operate through different mechanisms of timing and spatial distribution.

What are the five phases of the Korotkoff sounds?
there are 5 phases
