Quiz on Stimulus-Elicited Behavior

What is the definition of stimulus-elicited behavior?

• A voluntary and delayed response to stimulation

• An involuntary and immediate response produced as a result of sensory stimulation

• A voluntary and immediate response to sensory stimulation

• An involuntary and delayed response to stimulation

Which of the following is an example of stimulus-elicited behavior?

• Planning a movement

• Startle reaction/reflex

• Deliberate decision making

• Voluntary muscle contraction

What is the key relationship in stimulus-elicited behavior?

• The connection between stimulus and voluntary response

• The connection between stimulus and response is crucial

• The connection between voluntary movement and reaction time

• The connection between response and delayed reaction

In the air-puff eye-blink reflex, what timing indicates a reflex?

• Less than 50 ms

• Greater than 200 ms

• 100-200 ms

• 200-300 ms

What characterizes reflexes as a type of stimulus-elicited behavior?

• Voluntary and modifiable

• Involuntary and immediate

• Delayed and voluntary

• Modifiable and delayed

What type of reflex is produced by the activity of smooth muscles, cardiac muscles, and glands?

• Autonomic Reflex

• Skeletomotor Reflex

• Somatic Reflex

• Visceral Reflex

Which type of motor neurons innervate only extrafusal muscle fibers?

• Alpha (α) Motor Neurons

• Gamma (γ) Motor Neurons

• Beta (β) Motor Neurons

• Delta (δ) Motor Neurons

What is the function of alpha motor neurons?

• Innervate extrafusal muscle fibers, causing muscular contraction

• Innervate intrafusal muscle fibers, causing muscle relaxation

• Transmit sensory information to the brain

• Control involuntary muscle movements

What is an example of a skeletomotor reflex?

• Acoustic startle reflex

• Pupillary light reflex

• Salivary reflex

• Gastrocolic reflex

How are extrafusal fibers organized in muscle composition?

• Into a smaller number of motor units

• Into a larger number of motor units

• Randomly distributed

• In a single continuous unit
