Which somatosensory system conveys discriminative touch, vibration, and proprioception?
Which somatosensory system conveys discriminative touch, vibration, and proprioception?
- Dorsal somatosensory system (correct)
- Anterolateral somatosensory system
- Both dorsal and anterolateral somatosensory systems
- None of the above
Why do techniques using SEPs selectively test the dorsal somatosensory system?
Why do techniques using SEPs selectively test the dorsal somatosensory system?
- It has abundant deep receptors for limb proprioception
- Its thick peripheral axons have low thresholds and fast, uniform conduction (correct)
- Its thinner axons have higher thresholds and slower, more variable conduction
- It carries pain, light touch, and temperature sensation
What type of receptors does the dorsal somatosensory system have?
What type of receptors does the dorsal somatosensory system have?
- Both a and c (correct)
- Cutaneous discriminative touch and vibration receptors
- Muscle spindle receptors
- Pain and temperature receptors
