The magnitude of a receptor potential determines the strength of the stimulus detected by the sensory receptor. A larger receptor potential indicates a stronger stimulus, while a smaller receptor potential indicates a weaker stimulus. This information is then transmitted to the central nervous system for further processing and perception.

When a stimulus is applied to a sensory ending what kind of potential is produced?
When a stimulus is applied to a sensory ending, it can lead to the generation of a receptor potential. This receptor potential is a graded potential that can trigger an action potential along the sensory neuron, leading to the transmission of the sensory input to the central nervous system for processing and interpretation.
WhatConversion of a stimulus into a generator potential is?
Receptor potential, a type of graded potential, is the transmembrane potential difference of a sensory receptor. A receptor potential is often produced by sensory transduction. It is generally a depolarizing event resulting from inward current flow. The influx of current will often bring the membrane potential of the sensory receptor towards the threshold for triggering an action potential. A receptor potential is a form of graded potential, as is a generator potential. It arises when the receptors of a stimulus are separate cells. An example of this is in a taste bud, where taste is converted into an electrical signal sent to the brain. When stimulated the taste bud triggers the release of neurotransmitter through exocytosis of synaptic vesicles from the presynaptic membrane. The neurotransmitter molecules diffuse across the synaptic cleft to the postsynaptic membrane. A postsynaptic potential is then produced in the first order neuron, and if the stimulus is strong enough to reach threshold this may generate an action potential which may propagate along the axon into the central nervous system
What change does ACh cause in an ACh receptor?
Acetylcholine (ACh) binding to an acetylcholine receptor triggers a conformational change in the receptor protein, leading to the opening of an ion channel within the receptor. This allows specific ions, such as sodium or potassium, to flow across the cell membrane, resulting in changes in membrane potential and ultimately leading to cellular responses.
How a drug interacts with a receptor?
A drug interacts with a receptor by binding to specific sites on the receptor, leading to changes in the conformation or activity of the receptor. This interaction can either activate or inhibit the receptor's function, ultimately affecting downstream signaling pathways and physiological responses within the body. The strength and specificity of this interaction determine the drug's effectiveness and potential side effects.
What is a simple neural receptor?
A receptor (protein) on a neuron that receives stimulus (light, pressure, chemical...etc). The stimulus generates a receptor potential (local disturbance/slight depolarization in membrane potential).
What is difference between generator potential and receptor potential?
it is
When a sensory neuron is excited by some of energy the resulting graded potential is called?
The resulting graded potential is called a receptor potential. This potential is generated in response to a stimulus and serves to initiate the transmission of sensory information to the central nervous system.
When a sensory neuron is excited by some energy the resulting graded potential is called?
Receptor potential or generator potential.

When was Transient receptor potential channel-interacting protein database created?
The Transient receptor potential channel-interacting protein (TRIP) database was created in 2006. It aims to provide a comprehensive resource for protein-protein interactions involving TRP channels and TRP channel-interacting proteins.
When a sensory neuron is excited by some form of energy the resulting graded potential is called a(n)?
When a sensory neuron is excited by some form of energy, the resulting graded potential is called a receptor potential. This receptor potential triggers the generation of an action potential that eventually leads to the transmission of sensory information to the central nervous system.

What is the voltage change at the receptor site of a neuron?
When a neuron is activated, there is a change in the voltage across the cell membrane at the receptor site. This change is known as a postsynaptic potential and can be either depolarizing (making the neuron more likely to fire an action potential) or hyperpolarizing (making the neuron less likely to fire an action potential).

What is receptor desensitisation?
Receptors generate a cellular response upon binding their specific ligand. This response can vary in magnitude. Desensitisation is a phenomenon in which activation of a receptor can reduce the magnitude of the response if it is subsequently activated again. Usually the longer a receptor is activated for the greater the desensitisation will be. There are 3 general mechanisms as to how desensitisation occurs. The first is uncoupling of the receptor from proteins which generate the cellular response. The second is internalising receptors so that they cannot be activated. The third is reducing production of receptors so less are available. In general mechanism 1 is short term, 2 is mid-term and 3 is long term.
