Slowly adapting receptors differ from rapidly adapting receptors in :-a- stopping to discharge after a relatively longer period of constant stimulationb- detecting the dynamic properties of stimulic- detecting velocity of stimulid- generating receptor potentials as long as stimulus is applied.
Once initiated, the receptor potential :-a- spreads to a long distance along the sensory nerve fiberb- amplitude is not related to the strength of the stimulusc- always generates an action potential from the receptord- stays for a variable period depending on the type of the receptor
When stimulated by effective steady stimuli, sensory receptors :-a- continuously discharge impulsesb- stop discharging after a short timec- produce an initial high rate of impulse discharge followed by decline of this rated- differ in their response ; some types discharge continuously, while other types do not respond at all
What is the relationship between stimulus strength and the resulting action potential amplitude in a single axon in the giant nerve fibers of the earth worm? O Increasing stimulus strength decreases the resulting action potential amplitude O Increasing stimulus strength does not change the resulting action potential amplitude Increasing stimulus strength increases the resulting action potential amplitude O Increasing stimulus strength can increase or decrease the resulting action potential amplitude depending on which axon it is recorded from
When people are tickled, light touch receptors are activated, causing a range of different responses, including squirming or movement away from the stimulus. Match the step in the tickle response homeostasis loop with the correct label
You are recording from a touch receptor in skin. When you stimulate a spot on the skin, the receptor fires continuously until you stop the skin stimulation. Which of the following pieces of information would you need to be able to identify what kind of receptor this is? Group of answer choices Whether the area of skin that can activate this receptor is big or small Whether the receptor sends its output to the somatosensory cortex or not You don’t need any more information; you can identify this receptor just from the information provided Whether the touch receptor is connected to an Alpha-Delta fiber or a C-fiber
How does lidocaine cause numbness when injected? destroys pain receptors repolarizes sensory axons blocks effectors from reaching threshold prevents voltage gated channels from opening
In a reflex response, such as if you touched a hot stove: O It involves decision making It involves conscious thought The receptor sends sensory information directly to the brain (Integrator) The receptor sends sensory information directly to the motor neuron (Effector)
Almost all neurons have Schwann cells where the cell receives stimuli Dendrites where process stimuli Axons where cells transmit stimuli All of the above are correct Only B and C are correct
In negative feedback systems the receptor sends a negative signal the stimulus is increased or amplified the effector reduces or eliminates the stimulus the control center receives input from the effector the receptor increases or enhances the stimulus
A reflex action :-a- is a fast brief response to a sensory stimulusb- is involved in regulation of voluntary movementsc- includes at least three sequential sets of neurons in its pathwayd- is always initiated whenever its specific receptors are effectively stimulated by a specific stimulus
An individual diagnosed with CMT has difficulty holding a cup because: a. The myelin in the motor neurons is damaged thereby preventing an impulse frommoving along the axonb. The myelin in the sensory neurons is damaged thereby preventing an impulse frommoving along the axonc. The dendrites in the motor neurons are damaged thereby preventing an impulse frommoving along the axond. The dendrites in the sensory neurons are damaged thereby preventing an impulse frommoving along the axon
