WebSize. Action potentials travel down neuronal axons in an ion cascade. Positive ions (mostly sodium ions) flow into the cell body, which triggers transmembrane channels at the start … WebThus, action potentials transmitted over a sensory receptor’s afferent axons encode one type of stimulus, and this segregation of the senses is preserved in other sensory circuits. For example, auditory receptors transmit signals over their own dedicated system, and electrical activity in the axons of the auditory receptors will be interpreted by the brain as …

WebConduction of nerve impulse occurs due to the presence of active and electronic potentials along the conductors. Transmission of signals internally between the cells is achieved through a synapse. Nerve conductors comprise relatively higher membrane resistance and low axial resistance. The electrical synapse has its application in escape ... Web• Postsynaptic potentials (PSPs) are elicited on the cell body and dendrites • PSPs are conducted decrementally to the axon • When the summated PSPs exceed the threshold of excitation at the axon, an action potential (AP) is triggered • The AP is conducted non-decrementally down the axon to the axon terminal • Arrival of AP at the axon terminal …
