WebAug 30, 2024 · How does the nerve impulse travel along the neuron? A nerve impulse may be defined as wave of depolarization of the membrane of the nerve cell. The nerve impulse travels along a neuron or across a synapse (junction), between one neuron and another, or between a neuron and an effector, such as a muscle or gland.

How do impulses cross the synapse? - Vedantu

WebAn axon or nerve fiber is a long, slender projection of a nerve cell or neuron in vertebrates that typically conducts electrical impulses known as action potentials away from the nerve cell body. The function of the axon is to transmit information to different neurons, muscles, and glands. Impulse is an electrical signal that travels along axon. 3. WebIf the neuron does end up firing, the nerve impulse, or action potential, is conducted down the axon. ...

Complete answer: An action potential starts at a presynaptic neuron as … WebWhat Synapses Do Synapses connect neurons and help transmit information from one neuron to the next. When a nerve signal reaches the end of the neuron, it cannot simply continue to the next cell. Instead, it must trigger the release of neurotransmitters which can then carry the impulse across the synapse to the next neuron.
