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).
Can graded potential form on receptor endings?
Yes, Graded potentials (otherwise known as postsynaptic potentials) can form on receptor endings.
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?
ACh binds to each ACH receptor which causes opening of ligand-regulated ion gate and the creation of end-plate potential.
Identify which of the stimulus modalities induced the largest amplitude receptor potential in the pacinian corpscle?
extreme pressure
What is difference between generator potential and receptor potential?
it is

When was Transient receptor potential channel-interacting protein database created?
Transient receptor potential channel-interacting protein database was created in 2010.

What is the voltage change at the receptor site of a neuron?
postsynaptic potential (PSP)
When a sensory neuron is excited by some form of energy the resulting graded potential is called?
receptor or generator potential
Differences between a channel and a receptor?
factors that influences conductivities of action potential
What is the receptor of a reflex arc?
Sensory receptor located at the distal end of a neuron or an associated sensory structure. When stimulated it creates a receptor potential, when that reaches its threshold, it will trigger 1 or more nerve impulses in the sensory neuron.
How do hormones establish selectivity?
Hormones are ligands that bond to cells and carry a specific receptor. The ligand bonds its receptor to form a complex that acquires a purpose. The ligand triggers a change in the receptor, which activates a potential biological function. Cells that do not exhibit the receptor never receive the signal.
