Question

Quizplus · Accepted Answer

A parietal lobe or sensory nerve tract dysfunction prevents a patient from identifying a familiar object by touch, which is a definition of stereognosis. Sensory and motor tracts travel though the midbrain and pons, but they are not tested with stereognosis. Ascending tracts carry sensory data, but the temporal lobe provides functions of hearing rather than perception of touch. Motor tracts carry impulses for movement and they exit from the frontal lobe, which also helps to maintain consciousness.
