WebThe action potential is essentially a brief increase in the permeability of the membrane to sodium, immediately followed by a brief increase in the permeability of the membrane to potassium. Once an action potential is generated it propagates all the way down the axon to the terminal button. WebBecause of properties related to sodium channels on the neuronal membrane that are involved in action potentials, there is a point at which a cell cannot fire any faster (Shamma, 2001). The place theory of pitch perception suggests that different portions of the basilar membrane are sensitive to sounds of different frequencies. did steve tell you that perchance

Several types of cells support an action potential, such as plant cells, muscle cells, and the specialized cells of the heart (in which occurs the cardiac action potential). However, the main excitable cell is the neuron, which also has the simplest mechanism for the action potential. Neurons are electrically excitable cells composed, in general, of one or more dendrites, a single soma, a single axon and one or more axon terminals. Dendrites are cellular projections whose pri… WebA) increases in conscious perception of a sensory stimulus. B) a characteristic of phasic receptors.

"WebThe formation of an action potential can be divided into five steps: (1) A stimulus from a sensory cell or another neuron causes the target cell to depolarize toward the threshold potential. (2) If the threshold of excitation is reached, all Na+ channels open and the membrane depolarizes. " - Incoming action potentials
