A sensory stimulus can generate a neural impulse, as can repeated or multiple inputs of neural signals from other neurons.
A neural signal is transmitted from one neuron to anotheracross a synapse via chemicals called neurotransmitters, and a neural impulse is transmitted along an axon of a neuron by either an action potential (in an unmyelinated axon) or by saltatory conduction (in a myelinated axon).
In the nervous system axons generate and transmit impulses.
The nerve impulse from your foot to your leg is called a sensory nerve signal or proprioceptive feedback. It helps transmit information about sensations such as touch, pressure, and position to the brain.
Yes, a stimulus needs to reach a certain threshold level of strength in order to generate a nerve impulse. This threshold is required to depolarize the cell membrane and initiate the action potential. If the stimulus is not strong enough to reach this threshold, no nerve impulse will be generated.
nerve impulse
The space through which a nerve impulse passes from one nerve cell to another is called a synapse. It is a small gap between neurons where neurotransmitters are released to transmit signals between the cells.
Myelinated nerve fibers transmit nerve impulses at the highest rate due to the presence of insulation provided by the myelin sheath. This insulation helps the nerve impulse jump quickly from one node of Ranvier to the next, allowing for rapid transmission.
a nerve impulse
Irritablity is the ability to respond to stimuli and convert it to nerve impulses. Conductivity is the ability to transmit that impulse.
neurotransmitters, which are chemical messengers that transmit signals between neurons. When a nerve impulse reaches the end of a neuron, it triggers the release of neurotransmitters into the synapse. These neurotransmitters then bind to receptors on the neighboring neuron, initiating a new nerve impulse to continue the signal transmission.
How does a nerve impulse follow the all-or-nothing principle???

Yes, an action potential is needed for a nerve impulse to occur.
