Question

multiple choice 2 points
which of the following is not a property of reflexes?
reflexes are quick responses of the nervous system.
reflexes do not require a stimulus.
reflexes are not voluntary.
reflex responses are very predictable.
reflexes are responses to sensory inputs.

Explanation:

Define properties of reflexes

Using the Autonomic Reflexes and Visceral Reflex Arc knowledge points

• Reflexes are rapid, involuntary, predictable, and stereotyped motor responses to a specific sensory stimulus.
• They always require a stimulus to initiate the sensory-to-motor pathway.

Evaluate the given options

• "Reflexes are quick responses of the nervous system" is a true property.
• "Reflexes do not require a stimulus" is false, as reflexes are always triggered by a sensory stimulus.
• "Reflexes are not voluntary" is a true property (they are involuntary).
• "Reflex responses are very predictable" is a true property (stereotyped).
• "Reflexes are responses to sensory inputs" is a true property.

Answer:

• Reflexes are quick responses of the nervous system.
• Reflexes do not require a stimulus. (Correct answer)
• Reflexes are not voluntary.
• Reflex responses are very predictable.
• Reflexes are responses to sensory inputs.
