Strong stimuli cause the amplitude of action potentials generated to increase?

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.

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.
What cells have the ability to respond to stimuli by generating signals such as action potentials?
neurons and muscle cells
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?
The CNS, chemoreceptors in the gut, the enteric nerve plexus.
An example of external stimuli in social care?
An example is the pineal gland responding to reduced daylight by the increase of the production of melatonin.Hope this help :)

The all or none principle states that?
The all-or-none principle in physiology states that once a nerve impulse reaches a certain threshold, a neuron will fire at its maximum potential. If the stimulus is strong enough to trigger an action potential, the response will occur at full strength. If the stimulus is below the threshold, no response will be triggered.

How are neural impulses generated?
The neural impulse is the electrical charge that goes from the nerve receptor to the brain. They are generated when the nerve receptor detects a foreign stimuli.
When stimuli were applied to the muscle frequently enough to cause a plateau in the amount of force generated?
Tetani

How does the muscle respond in reflex action?
Nerves are bundles of axons and their sheaths of connective tissue that extend from the CNS to peripheral structures,Nerves are responsible for stimuli communication and responceThe Central nervous system CNSBrainSpinal CordThe Prephrial nervous system PNSCranial nerves, which arise from the brain Sensory/ afferent transmits STIMULI from the sensory organs to the CNSMotor/ efferent-transmits action potentials from the CNS to effector organs when a Stimuli is recieved causing some sort of reaction.Spinal nerves, which arise from the spinal cordIf the sensory Stimuli was an itch on the tip of your nose the motor action potential generated would send your hand to your nose to scratch the itch.
When the interval between the stimuli decreases a second action potential is generated how?
When the interval between stimuli decreases, the membrane potential of the neuron has not fully returned to its resting state before the next stimulus arrives. This allows the neuron to quickly reach the threshold for generating a second action potential without returning to baseline. This phenomenon is known as temporal summation, where the combined effect of multiple stimuli within a short time frame can lead to the generation of subsequent action potentials.
What does Weber's law refers to?
Weber's law, also known as the Weber-Fechner law, states that the just noticeable difference between two stimuli is proportional to the magnitude of the stimuli. In other words, the difference threshold increases as the intensity of the stimulus increases. This law is often used to study perception and how we detect differences in stimuli.
What part of the ear converts vibrations to action potentials?
The inner ear contains the receptors for sound which convert fluid motion into action potentials that are sent to the brain to enable sound perception. The airborne sound waves must be transferred into the inner ear for hearing to occur.
What is the role of the neurons in transmitting electrochemical impulses?
They send the chemical impulses that are released at the synapses from the synaptic terminal of the axon of the first neuron. It merges from the dendrites to the second neuron.
