FAQs
Question: What are the main components of a reflex arc? Answer: The main components of a reflex arc include the sensory receptor, sensory neuron, interneuron, motor neuron, and effector.
Question: How do reflexes differ from voluntary actions? Answer: Reflexes are involuntary responses to stimuli, while voluntary actions involve conscious thought and decision-making.
Now is the time to enhance your understanding of neurophysiology! Solve practice MCQs and test your knowledge on "Neurophysiology: Reflexes and Pathways - Physiology Case Studies". This will not only boost your confidence but also prepare you for success in your exams.
Q. In a simple reflex arc, which component detects the stimulus?
A.
Effector
B.
Interneuron
C.
Sensory receptor
D.
Motor neuron
Solution
The sensory receptor detects the stimulus and initiates the reflex arc by sending signals to the central nervous system.
Q. What is the primary purpose of the stretch reflex?
A.
To protect the body from injury
B.
To maintain posture and balance
C.
To enhance muscle strength
D.
To facilitate voluntary movement
Solution
The primary purpose of the stretch reflex is to maintain posture and balance by automatically adjusting muscle tension in response to changes in muscle length.
Correct Answer:
B
— To maintain posture and balance
Q. Which type of reflex involves the contraction of muscles on the opposite side of the body?
A.
Monosynaptic reflex
B.
Polysynaptic reflex
C.
Reciprocal reflex
D.
Crossed extensor reflex
Solution
The crossed extensor reflex involves the contraction of muscles on the opposite side of the body in response to a stimulus, providing balance and support.
