Do action potentials in the same neuron come in different sizes and shapes?
Yes, but that is not relevant. The important thing is the frequency of action potential
Which of the following is one of the four steps in the execution sequence of after action review?
mentoring
Which of the following is one of the four parts of the after action review?
Determine how to do the task differently next time.
Which of the following would have the fastest conduction of an action potential?
myelinated, large diameter fibres
Which type of axon will velocity of action potential conduction be the fastest?
Myelinated axons with a larger diameter will conduct action potentials the fastest due to saltatory conduction, where the action potential jumps from one node of Ranvier to the next, skipping the myelin-covered regions. Smaller-diameter and unmyelinated axons will conduct action potentials more slowly.
What does a conduction velocity of an action potential depend on?
The conduction velocity of an action potential depends on the diameter of the axon and the presence of a myelin sheath. A larger axon diameter and the presence of myelin increase conduction velocity by allowing for faster propagation of the action potential.
What type of cell enhances the velocity of electrical transmission of an action potential along an axon in the peripheral nervous system?
Schwann cells enhance the velocity of electrical transmission of an action potential along an axon in the peripheral nervous system by forming a myelin sheath around the axon. This myelin sheath insulates the axon, allowing for faster conduction of the action potential through a process known as saltatory conduction.
What type of cell enhances the velocity of electrical transmission of an action potential along an axon in the central nervous system?
Oligodendrocyte
What is the relationship between the action potential and the synapse?
A synapse and an action potential have a flip-flopping cause and effect relationship, in that an action potential in a presynaptic neuron initiates a release of neurotransmitters across a synapse, which can then subsequently potentially trigger an action potential in the axon of the postsynaptic neuron, which would then cause release of neurotransmitters across a following synapse.
Is fastest an action verb?
No because you can't fastest.
What are actions potentials?
In physiology, an action potential is a short-lasting event in which the electrical membrane potential rapidly rises and falls, following a consistent trajectoryAn action potential occurs when a neuron sends information down an axon, away from the cell body.
Which of the following best describes the events of excitation in excitation-contraction coupling?
Propagation of the action potential along the sarcolemma
What does the velocity of action potential transmission depends least on what?
For an action potential to transmit it's dependent on three major factors. 1. Size of action potential - greater size and rate of depolarization greater the action potential 2. Cell diameter- greater diameter, greater potential think of water pipes, wider pipes potentially carry more water 3. Myelination. For the idiot that said friction, in the world of neuroscience in which this question was posted under, friction is not the right answer. You are not physically moving something. It's all about conductance, read the right chapter in physics. Myelination reduces current leaks allowing the majority of conductance to reach the node. Thus myelination increases speed and strength of transmissions. Velocity is least dependent on anything other than these three. I hope that answers your question. However, it was kind of vague so, working bakeries from the question seemed the best way to go
What is relative refactory period?
The relative refractory period is the phase of the cardiac action potential during which a stronger-than-usual stimulus is required to elicit another action potential. It occurs immediately following the absolute refractory period and allows for the heart muscle to be able to respond to a second, stronger stimulus after the initial action potential.
What is negative after-potential?
The negative after-potential is a brief hyperpolarization phase following an action potential in a neuron. This phase occurs as potassium ions continue to exit the cell, leading to a temporary increase in membrane potential beyond the resting state. It is important for re-establishing the resting membrane potential and preparing the neuron for the next action potential.
