Information about sound waves travels as action potentials via the auditory nerve from the cochlea to the lobe for processing?
Sound waves enter the ear and are converted into electrical signals by hair cells in the cochlea. These signals are sent as action potentials along the auditory nerve to the brain, specifically to the auditory cortex in the temporal lobe, where they are processed and interpreted as sound.
What structures carry action potentials caused by sound transduction?
Action potentials caused by sound transduction are carried by the auditory nerve fibers, which are part of the vestibulocochlear nerve (cranial nerve VIII). These nerve fibers transmit the signals from the hair cells in the cochlea to the brainstem and auditory cortex for processing.
Will a hyperpolarization graded potential lead to an action potential?
No, hyperpolarization graded potentials do not lead to action potentials. Hyperpolarization makes the membrane potential more negative, which inhibits the generation of an action potential by increasing the distance from the threshold potential needed to trigger an action potential.
What is the regeneration of action potential called?
The regeneration of action potential is called "propagation." It involves the transmission of the action potential along the length of the neuron's axon.
What transmission of the depolarization wave along the neurons membrane?
Action potential

What part of the ear converts vibrations to action potentials?
The inner ear contains the receptors for sound which convert fluid motion into action potentials that are sent to the brain to enable sound perception. The airborne sound waves must be transferred into the inner ear for hearing to occur.
What was the effect of curare on eliciting an action potential?
It creates an action potential
Will a hyperpolarization graded potential lead to an action potential?
No, hyperpolarization graded potentials do not lead to action potentials. Hyperpolarization makes the membrane potential more negative, which inhibits the generation of an action potential by increasing the distance from the threshold potential needed to trigger an action potential.

Why does curare create an action potential?
Curare does NOT create an action potential. It binds to nicotinic acetylcholine receptors (which are primarily excitatory), and prevents the formation of an action potential.
Also called a nerve impulse transmitted by axons?
action potential
Why does curare appear to generate an action potential?
It doesn't. I prevents an action potential from forming.
What transmission of the depolarization wave along the neurons membrane?
Action potential
Can subthreshold stimulation cause an action potential?
No, subthreshold stimulation is not sufficient to trigger an action potential. The membrane potential needs to reach a certain threshold level for an action potential to be generated. Subthreshold stimulation only produces graded potentials that do not reach the threshold for firing an action potential.
