Why does the polarity of a cell membrane reverse during an action potential?
During an action potential the neuron receives a stimulus causing the cell membrane to become more permeable to sodium than potassium, calling the polarity to change.
What is restpotential?
The resting membrane potential of a neuron is about -70 mV (mV=millivolt) - this means that the inside of the neuron is 70 mV less than the outside. At rest, there are relatively more sodium ions outside the neuron and more potassium ions inside that neuron.
What is it called more than one stimulus is added together?
Stimuli
When a neuron is resting the inside of the cell membrane is?
When a neuron is resting then inside of the cell membrane is more negative than outside.
What do resting and action potentials depend on?
The resting and action potentials depend on the balance of charges of the area outside the neuron and inside the neuron. A resting potential is when the neuron is more negatively (approximately -70mv) charged than the area outside the neuron. The action potential occurs when sodium ions rush into the neuron, causing the polarity to be reversed. When there is no difference in charge between the area inside the neuron and the area outside the neuron, no action potentials can be started by that neuron.
What is the definition of a submaximal stimulus?
Submaximal Stimulus results in complete contraction of some fibers. It causes contraction more than subminimal stimulus and less than maximal stimulus.
Why does the polarity of a cell membrane reverse during an action potential?
During an action potential the neuron receives a stimulus causing the cell membrane to become more permeable to sodium than potassium, calling the polarity to change.
A typical neuron has more than one of what?
axon
A typical neuron has more than one?
axon
How do you spell more than one stimulus?
The plural form of stimulus is stimuli.
What is restpotential?
The resting membrane potential of a neuron is about -70 mV (mV=millivolt) - this means that the inside of the neuron is 70 mV less than the outside. At rest, there are relatively more sodium ions outside the neuron and more potassium ions inside that neuron.
What is definition of novel stimuli?
More than one new stimulus
What is it called more than one stimulus is added together?
Stimuli
How do you spell stimulus if there is more than one?
The Latin plural of stimulus is stimuli. However, there is also an informal English form stimuluses.
When a neuron is resting the inside of the cell membrane is?
When a neuron is resting then inside of the cell membrane is more negative than outside.
What is the correct order of components of a reflex arc?
The three-neuron arc is the most common and consists of the afferent neurons, interneurons, and the efferent neurons. Afferent neurons conduct impulses to the CNS from the receptors. Efferent neurons conduct impulses from the CNS to effectors (muscle or glandular tissue). Two-neuron arc is the simplest form, fastest responding and consists of afferent and efferent neurons. Example is the knee-jerk reflex.
Can a neuron have more than two axons?
No. They can have 1,000 dentrites but only one axon.
