A period after an initial stimulus when a neuron is not sensitive to another stimulus is the?
After the generation and propagation of an action potential along a neuron, the cell becomes depolarized to the point where there is no potential for further signaling until the cell re-polarizes through the action of ion pumps. This very brief period is called the refractory state.
What else can I help you with?
When a neuron receives a stimulus that is very strong?
When a neuron receives a very strong stimulus, it may reach its threshold potential and fire an action potential. This can lead to the release of neurotransmitters, sending a signal to other neurons. The strength of the stimulus can affect the frequency of action potentials generated by the neuron.
During the absolute refractory period along an axon membrane of a neuron?
During the absolute refractory period, the neuron is unable to generate another action potential, regardless of the stimulus strength. This is because sodium channels are inactive and unable to open. This period ensures that action potentials are discrete and travel in one direction along the axon.
What are the first and last elements in a spinal reflex?
The first element in a spinal reflex is the sensory receptor, which detects a stimulus. The last element is the effector, which carries out a response to the stimulus.
What is the relationship between the absolute and relative refractory periods in the context of neuronal excitability?
The absolute refractory period is the time when a neuron cannot generate another action potential, regardless of the stimulus strength. The relative refractory period is the time when a neuron can generate another action potential, but only with a stronger stimulus. These periods help regulate neuronal excitability by ensuring that neurons fire in a controlled manner and prevent excessive firing.
What is the difference between the absolute refractory period and the relative refractory period in terms of neuronal excitability?
The absolute refractory period is a time when a neuron cannot respond to any stimulus, no matter how strong. The relative refractory period is a time when a neuron can respond to a stronger stimulus than usual.
The period after initial stimulus when I neuron is not sensitive to another stimulus is the?
The period after an initial stimulus when a neuron is not sensitive to another stimulus is called the refractory period. During this time, the neuron is recovering and cannot generate another action potential, which ensures that signals are transmitted in one direction and helps maintain the integrity of the nerve signal. The refractory period can be divided into two phases: the absolute refractory period, where no stimulus can trigger an action potential, and the relative refractory period, where a stronger-than-normal stimulus is required to elicit a response.
How is a stimulus transmitted across a synapse?
Neurons are responsible for transmitting a stimulus across a synapse. The electric potential of the neuron is sensitive to changes in the resting state and sets off electric transmissions.
How does a neuron indicate the strength of a stimulus?
A neuron conveys information about the strength of stimuli by varying the rate in which the stimulus is fired.
What neuron picks up a stimulus?
A sensory Neuron picks up the stimulus from the environment and changes it into a nerve impulse.
Which neurons decide about the action for a certain stimulus?
Sensory neuron
What is the stimulus-response pathway involving a sensory neuron and a motor neuron?

What makes a neuron receive a stimulus?
An interaction with the world.
What happens at the level of the neuron starting with stimulus and ending with a response?
The stimulus is detected by the sensory receptor. The sensory receptor stimulates a sensory neuron. The sensory neuron transmits to the interneuron in the spinal cord. The interneuron stimulates a motor neuron. The motor neuron communicates to the muscle. The muscle(effector) then produces the response allowing the body to respond to the stimulus.
The strong stimulus can increase the?
Number of times the neuron fires
What is the pathway a stimulus followed to produce a response?
the neuron pathway
When a stimulus acts on a neuron it decreases the permeability of the stimulated point of its membrane to sodium ions?
False( When a stimulus acts on a neuron, it increases the permeability of the stimulated point of its membrane to sodium ions. )
When a neuron receives a stimulus that is very strong?
When a neuron receives a very strong stimulus, it may reach its threshold potential and fire an action potential. This can lead to the release of neurotransmitters, sending a signal to other neurons. The strength of the stimulus can affect the frequency of action potentials generated by the neuron.
