Frequently Asked Questions

What is nerve impulse?

Definition of nerve impulse : the progressive physicochemical change in the membrane of a nerve fiber that follows stimulation and serves to transmit a record of sensation from a receptor or an instruction to act to an effector

What happens during the transmission of nerve impulse?

Transmission of Nerve Impulses. Transmission of Nerve Impulses. The transmission of a nerve impulse along a neuron from one end to the other occurs as a result of electrical changes across the membrane of the neuron.

What is an all or Nothing event in impulse transmission?

Transmission of Nerve Impulses. The action potential is an all‐or‐nothing event: When the stimulus fails to produce depolarization that exceeds the threshold value, no action potential results, but when threshold potential is exceeded, complete depolarization occurs.

What triggers nerve impulse generation?

Generation of nerve impulse is dependent on the strength of a stimulus, which in turn, triggers both chemical and electrical changes in neurons. Notably, the neural membrane harbours several ion channels which are selectively porous to different ions. When a specific neuron is resting, its axonal membrane is relatively porous to potassium ions.
