Deforming the corpuscle creates a generator potential in the sensory neuron arising within it.
2.
This is a graded response : the greater the deformation, the greater the generator potential.
3.
The calcium dependent opening of TRPM5 produces a depolarizing generator potential which leads to an action potential.
4.
This is a graded response, meaning that the greater the deformation, the greater the generator potential.
5.
Upon reaching receptors on the postsynaptic spiral ganglion neurons, the neurotransmitters induce a postsynaptic potential or generator potential in the neuronal projections.
6.
If the generator potential reaches threshold, a volley of action potentials ( nerve impulses ) are triggered at the first node of Ranvier of the sensory neuron.
