What else can I help you with?
Which term does not belong excitability response to a stimulus contractility action potential?
The term that does not belong is "action potential." While excitability, response to a stimulus, and contractility are all related to muscle function and the ability of muscle fibers to react to stimuli, an action potential refers specifically to the electrical impulse that triggers these processes.
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 does propogation of an action potential mean?
Propagation of an action potential refers to the transmission of the electrical signal along the length of a neuron's axon. This is achieved through a series of depolarization and repolarization events that allow the action potential to travel in a rapid and coordinated manner from the cell body to the axon terminals. The propagation process ensures that information is effectively communicated from one part of the neuron to another.
What transmission of the depolarization wave along the neurons membrane?
Action potential
Which term does not belong excitability response to a stimulus contractility action potential?
The term that does not belong is "action potential." While excitability, response to a stimulus, and contractility are all related to muscle function and the ability of muscle fibers to react to stimuli, an action potential refers specifically to the electrical impulse that triggers these processes.
What is the difference between stored and action energies?
Stored energy refers to potential energy that is stored within an object due to its position or condition, such as gravitational potential energy or elastic potential energy. Action energy, on the other hand, refers to the energy associated with the movement or motion of an object, such as kinetic energy. Stored energy can be converted into action energy and vice versa based on the conditions and interactions of the system.
What was the effect of curare on eliciting an action potential?
It creates an action potential
What role to polarity and action potential play in sending out nervous signals?
Polarity refers to the difference in charge across a neuron's membrane, which is essential for generating an action potential. When a neuron is stimulated, depolarization occurs, leading to a rapid influx of sodium ions and a transient reversal of polarity. This action potential propagates along the axon, allowing the transmission of electrical signals. Ultimately, the action potential triggers neurotransmitter release at the synapse, facilitating communication between neurons.
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.
