Which type of summation is the result of numerous nerve impulses arriving at a synapse at closely timed intervals?
Temporal summation
Why electrical impulses are referred to as neural impulses?
Electrical impulses are referred to as neural impulses because a neural impulse cause electrical impulses. Neurons use electrical impulses to send messages.
Numerous nerve impulses arriving at a synapse at the same time exert a cumulative effect?
Kind of. Each neurone can have thousands of inputs from other neurones arriving at the same time. It all depends on the types of signal arriving from the other neurones. There are 2 types of incoming signal; 1. Excitatory Post-synaptic potentials (EPSPs) - These inputs depolarise the neurone (bring the negative voltage of the neurone closer to 0mV). 2.Inhibitory Post-synaptic potentials (IPSPs) - These inputs hyperpolarise the cell (make the neurone voltage more negative). Some of the inputs coming to the neurone will be EPSPs, some IPSPs. If all the inputs come in and there are more EPSPs then the neurone will depolarise. If the neurone depolarises to the firing threshold (around -40mV) then an action potential will be propagated and the neurone will transmit the message to the next neurone in the chain. If the majority of the inputs are IPSPs then the neurone will hyperpolarise and will not fire. If there are more EPSPs than IPSPs but the neurone still doesn't depolarise enough to reach the firing threshold then the neurone will not fire.
Transfer incoming impulses to outgoing impulses?
If counter imotion bring then incomin impulses can slow
Where does the interneuron carry impulses?
where does the unterneuron carry impulses
Does a dendrite carry impulses away?
They carry impulses to the cell body. Axons carry impulses away from the cell body.
What is the message called that a neuron carries?
nerve impulses
Are Nerve impulses electrical signaled?
Nerve impulses are electrical signals.
What nerve is a mixed cranial nerve that conducts sensory impulses from and motor impulses from and motor impulses to the thoracic and abdominal viscera?
vagus nerve
What does Mv means in Nerve Impulses?
Nerve impulses are measured in MiliVolts (mv)
What are the release dates for Impulses - 1959?
Impulses - 1959 was released on: USA: 1959
What conducts impulses in medical terms?
Nerves conduct impulses in medical terms.
