Sensation quiz

Which spinal tract relays information regarding discriminative sensations (including but not limited to light touch, proprioception, and vibration)? (full name excluding the word "system")

Which spinal tract is responsible for relaying information regarding pain, temperature, and crude touch? (full name excluding the word "system")

The right fasciculus gracilis relays which of the following information?

• Two-point discrimination of the right upper extremity

• Sharp dull of the right lower extremity

• Proprioception of the right lower extremity

• Vibration of the left lower extremity

Pain (pinprick or sharp/dull) is considered which general type of sensation?

• Superficial

• Deep

• Combined cortical

Examining proprioception involves:

• Determining joint position when the joint is still (at rest)

• Determining joint position while the joint is currently moving

• Duplicating the movement with the contralateral extremity while the joint is moving

• Identifying the presence of vibration on the skin surface

Identifying objects placed on the hand with vision occluded is an assessment of:

• Graphesthesia

• Stereognosis

• Barognosis

• Sensory extinction

Which of the following is true regarding the sensory hierarchy?

• We typically assess superficial and deep sensations before combined cortical

• If light touch is completely absent you should still assess stereognosis

• We typically assess every single superficial, deep, and combined cortical test on every patient

• Combined cortical sensations do not rely on the presence of deep sensation

A strict dermatomal pattern of sensory loss would be expected in:

• A patient post-stroke

• A patient with an isolated ulnar nerve injury

• A patient with diabetic polyneuropathy

• A patient with a lumbar radiculopathy
