Reflex

A reflex arc is a cerebral cortex level process

• True

• False

In a monosynaptic reflex arc, the afferent neuron carries

• motor

• sensory

You assess your patient's patellar tendon DTR and note that it's a 3+. This means that:

• Sustained response / clonus

• Minimal / Decreased response

• Normal response

• Brisk/strong, exaggerated response

Hypertonia typically involves:

• Lower motor neuron

• Upper motor neuron

In considering tone vs. spasticity, the biggest difference is that:

• Spasticity is velocity dependent

• Spasticity is based on ROM availability

• Tone is only when there's a catch and release in ROM

• Tone has to do with the upper body only

In a monosynaptic reflex arc, the synapse happens in the:

• Basal ganglia

• Cerebral cortex

• Spinal cord

• Mechanoreceptors

What is the first step in eliciting a deep tendon reflex?

When eliciting a deep tendon response, you want the joint to be positioned in:

• End range extension

• End range flexion

• Neutral

• Flexed to exactly 45 degrees
