The patient has impaired tactile sensation and proprioception on one side of the body below the level of the lesion. Which pathway is most likely damaged?

• Tractus spinothalamicus lateralis

• Tractus spinocerebellaris anterior

• Fasciculus gracilis

• Tractus cortico-spinalis anterior

When the anterolateral cord is affected, the patient complains of loss of pain and temperature sensitivity. Which pathway is affected

• Tractus spinothalamicus lateralis

• Fasciculus cuneatus

• Tractus rubrospinalis

• Tractus corticospinalis lateralis

Impaired coordination of movements and decreased muscle tone on one side of the body indicate damage to which pathway?

• Tractus spinocerebellaris posterior

• Tractus spinothalamicus anterior

• Tractus cortico-spinalis anterior

• Fasciculus gracilis

• Tractus cortico-spinalis lateralis

• Tractus spinothalamicus anterior

• Tractus spinocerebellaris posterior

• Fasciculus cuneatus

When the tractus rubrospinalis is damaged, the following is disrupted:
