Chapter 16 Reflex Quiz | BSN 1 Block 1 – Oct 21, 2025

During a routine check, your instructor taps your patellar tendon and your leg kicks forward. What reflex are you demonstrating?

• Plantar reflex

• Stretch reflex

• Pupillary reflex

• Corneal reflex

Which muscle is responsible for the leg’s forward movement during the patellar reflex?

• Hamstring muscle

• Gastrocnemius muscle

• Quadriceps femoris muscle

• Tibialis anterior muscle

What detects the initial stretching in the patellar reflex?

• Golgi tendon organ

• Muscle spindle

• Motor neuron

• Interneuron

The main purpose of the stretch reflex is to:

• Relax the stretched muscle

• Maintain posture and muscle tone

• Stop voluntary motion

• Increase blood flow

When the quadriceps contract, the hamstrings relax. What is this called?

• Reciprocal inhibition

• Reflex fatigue

• Parallel inhibition

• Crossed extension

Where does the processing or integration of the stretch reflex occur?

• Brainstem

• Cerebellum

• Spinal cord

• Motor cortex

While standing upright, you sway slightly but don’t fall. Which reflex helps you maintain balance automatically?

• Pupillary reflex

• Corneal reflex

• Stretch reflex

• Plantar reflex

During the patellar reflex test, no movement occurs because the hammer hit the bone instead of the tendon. What is the reason for the absent response?

• Damaged spinal cord

• Improper technique

• Muscle fatigue

• Blocked neuron pathway

A nurse gently strokes the sole of an adult patient’s foot from heel to toes. The toes curl downward. What does this indicate?

• Abnormal response

• Normal plantar reflex

• Voluntary movement

• Absent reflex

Why should the patient’s foot be kept relaxed during the plantar reflex test?

• To allow accurate observation of the reflex response

• To prevent pain

• To reduce fatigue

• To increase muscle contraction
