Resting potential
What else can I help you with?
The abrupt shift in the charge of a neuron from a negative to a positive charge is known as?
It is probably called as action potential.
What is a neural impulse?
A neural impulse, also known as an action potential, is a rapid electrical signal that travels along the axon of a neuron. It occurs when a neuron is activated by stimuli, causing a temporary change in the electrical charge across its membrane. This change allows the neuron to communicate with other neurons, muscles, or glands, facilitating the transmission of information within the nervous system. The process is essential for functions such as reflexes, muscle contraction, and sensory perception.
Where is the neuron?
The Inter-neuron (also known as the local circuit neuron, relay neuron or the association neuron) is the neuron which connects the afferent and the efferent neurons in the neural pathways.
In the myelinated neuron the myelin sheaths are separated by a small gap called that facilitates the neural impulse to jump from one point to another?
In myelinated neurons, the myelin sheaths are separated by small gaps called nodes of Ranvier. These nodes facilitate a process known as saltatory conduction, allowing the neural impulse to jump from one node to the next. This speeds up the transmission of electrical signals along the axon, enhancing the efficiency of neural communication.
What does the axon bulb do?
It starts the transmission of a neural signal from one neuron to another.An axon ends in an axon terminal, which ends in a small rounded tip called the axon bulb. Each terminal lies very close to either a dendrite or a cell body of another neuron, and the combination of the end of the first neuron, the beginning of the next, and the space between them is known as a synapse; when a neural impulse reaches the axon bulb, it is stimulated to release chemical messengers called neurotransmitters into the synaptic cleft (gap), which diffuse over to the second neuron, conveying the signal to the second neuron.
Period whereby no neural impulse can be generated even with intense stimulation?
The period during which no neural impulse can be generated, even with intense stimulation, is known as the refractory period. This phase occurs after an action potential has been initiated and involves a brief recovery time during which the neuron cannot fire again. The refractory period ensures that action potentials are unidirectional and helps to regulate the frequency of neuronal firing. It is divided into two phases: the absolute refractory period, where no impulses can be generated, and the relative refractory period, where a stronger-than-usual stimulus is required to elicit an action potential.
Where are the cell bodies in relay neuron?
The Inter-neuron (also known as the local circuit neuron, relay neuron or the association neuron) is the neuron which connects the afferent and the efferent neurons in the neural pathways.
What part of a neuron that relays a neural information?
The synapse. See my answer for What_type_of_signal_is_taking_place_during_neuron_to_neuron_communication
Minimum level of stimulation required to trigger a neural impulse?
The minimum level of stimulation required to trigger a neural impulse is known as the "threshold." This threshold is the minimum amount of neurotransmitter release or electrical stimulation needed to generate an action potential in a neuron. Below this threshold, the neuron will not fire an action potential.
What is the myelin sheath's function?
The function of the myelin sheath is to insulate the axon of the neuron. When there are gaps in the sheath, known as nodes of Ranvier, the nerve impulse can jump from gap to gap, thus increasing greatly the speed of conduction of the nerve impulse. This is known as saltatory conduction.

The small change in the charge across a neuron's membrane is known as the action potential. It is a brief electrical impulse that travels along the neuron's membrane, allowing for the transmission of signals between neurons.
