Which part of the neuron is capable of generating an action potiental?

The axon hillock is the part of the neuron that is capable of generating an action potential. It integrates incoming signals from the dendrites and, if the threshold is reached, triggers the action potential to be propagated down the axon.


How does an action potential differ from a graded potential?

An action potential is a rapid and all-or-nothing electrical signal that travels along the axon of a neuron, while a graded potential is a small and variable electrical signal that occurs in response to a stimulus. Action potentials are typically generated in neurons, while graded potentials can occur in various types of cells.


What substances plays the major role in generating the membrane potential of a neuron?

Ions, such as potassium (K+), sodium (Na+), and chloride (Cl-), play a major role in generating the membrane potential of a neuron. These ions create a difference in electrical charge across the neuron's membrane, which is essential for transmitting nerve impulses.


The trigger zone of a neuron includes?

The trigger zone of a neuron includes the axon hillock, where graded potentials are summed together to determine if an action potential will be initiated. It is the region where voltage-gated sodium channels are concentrated and play a crucial role in generating an action potential. If the depolarization at the trigger zone reaches a certain threshold, an action potential will be generated and propagated down the axon.


What substances plays a mojor role in generating the membrane potential of a neuron?

Well, for starters, membrane potential is a separation of charges across the membrane. So i think what you mean is "generating the action potential in a neuron". So in that case The substance that plays a major role in generating an action potential is Sodium (Na+). However, if you really mean membrane potential, there is only two substances associated with that and those are sodium (Na+) and potassium (K+).However, in truth, the generation of an action potential depends on the ligand and its receptor.

When a sensory neuron is excited by some form of energy the resulting graded potential is called?

The resulting graded potential is called a generator potential when a sensory neuron is excited by some form of energy. This potential may trigger an action potential if it reaches threshold.


When a sensory neuron is excited by some energy the resulting graded potential is called?

Receptor potential or generator potential.


Is a postsynaptic potential a graded potential that is the result if a neurotransmitter released into the synapse between two neurons?

Yes it is true that graded potential can be called postsynaptic potentials. When a sensory neuron is excited by some form of energy, the resulting graded potential is called generator potential.


When a sensory neuron is excited by some form of energy the resulting graded potential is called a(n)?

When a sensory neuron is excited by some form of energy, the resulting graded potential is called a receptor potential. This receptor potential triggers the generation of an action potential that eventually leads to the transmission of sensory information to the central nervous system.


What is local graded potential?

Local graded potentials are small changes in membrane potential that occur in response to neurotransmitter binding to ligand-gated ion channels on the post-synaptic neuron. These potentials can summate and affect the likelihood that an action potential will be generated in the neuron. They are also referred to as synaptic potentials.


Which membrane potential occurs because of the influx of Na plus through chemically gated channels in the receptive region of a neuron?

The membrane potential that occurs due to the influx of Na+ through chemically gated channels in the receptive region of a neuron is called the excitatory postsynaptic potential (EPSP). This influx of Na+ leads to depolarization of the neuron, bringing it closer to the threshold for generating an action potential. EPSPs can summate to trigger an action potential if they reach the threshold potential.

Is it true that a post synaptic potential is a graded potential that is the result of a neurotransmitter released into the synapse between two neurons?

Yes, that is correct. A postsynaptic potential is a localized change in the membrane potential of a postsynaptic neuron in response to neurotransmitters binding to receptors on its membrane. This results in a graded potential that can either excite or inhibit the postsynaptic neuron's firing.


When a sensory neuron is excited by some of energy the resulting graded potential is called?

The resulting graded potential is called a receptor potential. This potential is generated in response to a stimulus and serves to initiate the transmission of sensory information to the central nervous system.
