Which spinal cord level is responsible for the knee jerk (patellar) reflex?
Answer: L3–L4
The patellar (knee jerk) reflex is mediated through the L3–L4 spinal cord segments.
A patient with a complete C6 spinal cord injury would retain which muscle function?
Answer: Wrist extensors
C6 innervates the extensor carpi radialis, so wrist extension is preserved in a complete C6 injury.
Which type of stroke causes deficits on the SAME side as the lesion?
Answer: Cerebellar stroke
Cerebellar lesions cause ipsilateral (same-side) deficits because the cerebellum controls the same side of the body.
The Romberg test primarily assesses which sensory system?
Answer: Proprioception
The Romberg test assesses proprioceptive (somatosensory) function by removing visual input while the patient stands.
Which gait deviation is most characteristic of a patient with foot drop?
Answer: Steppage gait
Steppage gait (exaggerated hip and knee flexion to clear the foot) is the compensatory pattern for foot drop.
Spasticity in upper motor neuron lesions is characterized by:
Answer: Velocity-dependent resistance
Spasticity is a velocity-dependent increase in tonic stretch reflexes, distinguishing it from rigidity.
