NEUROLAB: 1st Shifting Flashcards
TRUE OR FALSE: The patellar reflex is an example of a monosynaptic reflex
True
TRUE OR FALSE: Hacking of the patellar tendon is an example of autogenic inhibition
False
TRUE OR FALSE: The presence of palmomental reflex in adults is ALWAYS a red flag
False
TRUE OR FALSE: The Golgi Tendon Organ is PURELY inhibitory
True
TRUE OR FALSE: Increased firing of Gamma Efferent Neurons results in hypertonic muscles
True
TRUE OR FALSE: Jendrassik Maneuver should be performed by the patient during DTR Assessment
False
TRUE OR FALSE: The central portion of the muscle spindle can contract and can be stimulated by stretch
False
TRUE OR FALSE: Dynamic Stretch Reflex is stimulated by rapid stretch or unstretch
True
Isometric contraction of the hamstring for 6 secs followed by stretching for 30 secs will result in an increased hip flexion ROM due to
A. Autogenic inhibition
B. Reciprocal inhibition
A. Autogenic inhibition
Which of the following can result to an increase jump height (based from your knowledge of stretch reflex)?
A. Bending for 20 secs prior to jumping
B. Quick bending in hip and knee prior to jumping

B. Golgi tendon organ
C. Both
D. Neither
A. Muscle spindle
It sends information to the nervous system about tension
A. Muscle spindle
B. Golgi tendon organ
C. Both
D. Neither
B. Golgi tendon organ
Inhibitory in nature
A. Muscle spindle
B. Golgi tendon organ
C. Both

This reflex is elicited by scratching the palmar area of the hand and observing contraction of the muscles of the chin or perioral area.
A. Grasping reflex
B. Moro reflex
C. Palmomental reflex
D. Rooting reflex
C. Palmomental reflex
This phenomenon occurs when the tension on the muscle and the tendon become extreme, the inhibitory effect from the Golgi tendon can be so great causing sudden reaction in the spinal cord leading to instantaneous relaxation of the entire muscle.
A. Lengthening reaction
B. Shortening reaction
A. Lengthening reaction
Nuclear chain fibers are innervated by:
A. Type Ia
B. Type II
C. Both type Ia & type II
D. Neither
C. Both type Ia & type II
Type of muscle sensory receptor
A. Muscle spindle
B. Golgi tendon organ
C. Both
D. Neither
C. Both
Patellar tendon was tapped which elicited brisk knee extension. What is the grade of the patientโs reflex?
A. 0
B. +1
C. +2
D. +3
E. +4
C. +2
Which of the following is/are primitive reflex/es?
A. Rooting reflex
B. Palmar grasp reflex
C. Both
D. Neither
C. Both
TRUE OR FALSE: Annulospiral sensory endings excite both the nuclear bag and the nuclear chain endings.
True
TRUE OR FALSE: Monosynaptic pathway allows a reflex signal to return with the shortest possible time delay back to the muscle after excitation of spindle.
True
TRUE OR FALSE: Golgi tendon reflex is entirely inhibitory in nature
True
TRUE OR FALSE: In autogenic inhibition, when the muscle tension becomes great, contraction suddenly ceases causing relaxation of the muscle
True
TRUE OR FALSE: Hypertonicity brought by loss of inhibition of gamma efferents can be evident in upper motor neuron lesions affecting the anterior horn cell.
False
