Yes.
....Up to a point. There is a threshold the stimulus must surpass before creating a CAP (compound action potential). Anything below this threshold is called subthreshold. Once the stimulus is strong enough cause a CAP it is a stimulus threshold. At this point the CAP will continue to increase as the intensity of the stimulus increases (now termed suprathreshold) until a maximal stimulus causes a maximum response.
Any stimulus stronger than the maximal stimulus is called a supramaximal and does not result in any larger a CAP than the maximum response caused by the maximal stimulus.

What else can I help you with?
Does strong stimuli cause the strength of action potentials to increase?
No, it doesn't become "larger" - the peak potential is always the same - it is a digital signal. Stronger stimulus will cause the nerve cell to fire more often - therefore stimulus strength is translated as action potential frequency.
Why are action potentials said to be all or none where as epsps and ipsps are described graded?
Action potentials are all-or-none responses because they will only occur if the stimulus reaches a certain threshold level. Once this threshold is met, the action potential will fire at its maximum strength. In contrast, EPSPs and IPSPs are graded because their amplitude can vary depending on the strength of their respective stimuli.
What cells have the ability to respond to stimuli by generating signals such as action potentials?
Nerve cells or neurons have the ability to respond to stimuli by generating signals such as action potentials. These signals travel along the nerve cells to communicate information within the nervous system.
Can graded potential form on receptor endings?
Graded potentials can form on receptor endings in response to stimuli such as pressure, temperature, or chemicals. These graded potentials can lead to the generation of action potentials that transmit the sensory information to the central nervous system for processing.
What type of tissues produce action potentials?
Excitable tissues, such as nerve and muscle tissues, produce action potentials. These tissues have specialized cells that are capable of generating and transmitting electrical signals in response to stimuli.

No, it doesn't become "larger" - the peak potential is always the same - it is a digital signal. Stronger stimulus will cause the nerve cell to fire more often - therefore stimulus strength is translated as action potential frequency.
Would increasing frequency of stimulation to trigger zone change number of action potentials?
Yes, increasing the frequency of stimulation can increase the number of action potentials generated in the neuron. This is known as frequency-dependent facilitation, where rapid succession of stimuli can enhance the excitability of the neuron and lead to more action potentials being fired.
Do sensory receptors fire action potentials in response to stimuli?
Yes, sensory receptors do fire action potentials in response to stimuli.

Action potentials are all-or-none responses because they will only occur if the stimulus reaches a certain threshold level.

In contrast, EPSPs and IPSPs are graded because their amplitude can vary depending on the strength of their respective stimuli.
Receptors provide information about the intensity of a stimulus through?
Receptors provide information about the intensity of a stimulus through the frequency of action potentials they generate. Higher intensity stimuli result in higher frequency of action potentials being sent to the brain, signaling a stronger stimulus. This frequency coding allows the brain to interpret the intensity of stimuli.

Nerve cells or neurons have the ability to respond to stimuli by generating signals such as action potentials. These signals travel along the nerve cells to communicate information within the nervous system.

Excitable tissues, such as nerve and muscle tissues, produce action potentials. These tissues have specialized cells that are capable of generating and transmitting electrical signals in response to stimuli.
What form of energy do all receptors output?
The receptors in our nervous system primarily output electrical signals known as action potentials. These signals are generated in response to specific stimuli detected by the receptors, such as touch, light, sound, or chemicals, and are used to transmit information to the brain for further processing.
What is the process in which our sensory receptors convert sensory stimuli from our environment into a form that can be sent to and used by the brain?
stem from generation of receptor potentials
4 Stimuli that regulate gastrointestinal tract activity are generated by what?
Stimuli that regulate gastrointestinal tract activity are generated by factors such as nervous system inputs, mechanical stretch of the intestinal wall, chemical stimuli from food and hormones released by the digestive organs. These stimuli play a crucial role in coordinating digestion and absorption processes in the gastrointestinal tract.
When stimuli were applied to the muscle frequently enough to cause a plateau in the amount of force generated?
Tetani
