How do graded potentials and action potentials differ in terms of their characteristics and functions?
Graded potentials are small changes in membrane potential that can vary in size and duration, while action potentials are brief, large changes in membrane potential that are all-or-nothing. Graded potentials are used for short-distance communication within a neuron, while action potentials are used for long-distance communication between neurons.

How do tonic and phasic firing patterns differ in terms of neuronal activity?
Tonic firing is a steady and continuous firing of action potentials in neurons, while phasic firing is a burst of action potentials followed by a period of inactivity. Tonic firing is more constant and maintains a baseline level of activity, while phasic firing is more dynamic and responsive to changes in stimuli.
What is the difference between plants and animals in terms of their biological characteristics and functions?
Plants and animals differ in their biological characteristics and functions. Plants are autotrophic, meaning they produce their own food through photosynthesis, while animals are heterotrophic and must consume other organisms for energy. Plants have cell walls made of cellulose, chlorophyll for photosynthesis, and do not have a nervous system. Animals have complex organ systems, mobility, and a nervous system for responding to stimuli.
How do neurotransmitters differ from hormones in terms of their functions and modes of action within the body?
Neurotransmitters are chemical messengers that transmit signals between nerve cells, while hormones are chemical messengers that regulate various bodily functions. Neurotransmitters act locally at synapses, while hormones travel through the bloodstream to target cells.
How does the end plate potential differ from a EPSP on a post synaptic cell?
End plate potential is the change in potential from neurotransmitters. It can be excitatory or inhibitory. If the action potential wants to continue, it will be excitatory and vice versa. It can be additive, if more action potentials are fired it will increase the end plate potential. An action potential is an all or none response. It will either proceed or it will not proceed depending on the terms of the threshold. It cannot be additive, because there is an absolute refractory period where no additional action potentials can be fired.
How do nerve cells differ from other types of cells in the body?
Nerve cells, also known as neurons, differ from other cells in the body because they are specialized for transmitting electrical signals and communication within the nervous system. Unlike most cells, nerve cells have long extensions called axons and dendrites that allow them to send and receive signals from other neurons. Additionally, nerve cells have a unique ability to generate and propagate action potentials, which are electrical impulses that allow for rapid communication between cells.
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 is a pacemaker potential and how does it differ from an action potential?
A pacemaker potential is a gradual depolarization that occurs in certain cardiac cells, primarily in the sinoatrial (SA) node, which allows them to generate rhythmic impulses automatically. Unlike action potentials, which are rapid and all-or-nothing responses that occur in neurons and muscle cells, pacemaker potentials are slower, non-threshold depolarizations that lead to spontaneous action potentials. This unique feature enables the heart to maintain a regular heartbeat without external stimulation. In summary, pacemaker potentials are a precursor to action potentials, specifically facilitating the heart's intrinsic rhythm.
How do tonic and phasic firing patterns differ in terms of neuronal activity?
Tonic firing is a steady and continuous firing of action potentials in neurons, while phasic firing is a burst of action potentials followed by a period of inactivity. Tonic firing is more constant and maintains a baseline level of activity, while phasic firing is more dynamic and responsive to changes in stimuli.
How do action replays differ from Gamesharks?
action replays differ from gamesharks in that action replays are newer and have less flaws, so your game will not freeze if u use it. I hope this was helpful.
