    Included Quiz Questions

    1. It is located on the lateral side in dorsal column from level CII—TVI.
    2. It is present throughout the spinal cord and receives sensory information from visceral organs.
    3. It is located on the medial side in the dorsal column and receives sensory information from upper extremities.
    4. It is located on the lateral side in dorsal column and receives sensory input from lower extremities.
    5. It is located on the medial side in dorsal column from level TII—TVI.
    1. Thalamus
    2. Somatosensory cortex
    3. Spinal Cord
    4. Midbrain
    5. Medulla
    1. Left fasciculus gracilis
    2. Right fasciculus graciis
    3. Left dorsal horn
    4. Right fasciculus cuneatus
    5. Left fasciculus cuneatus
    1. 2nd order neuron resides in medulla and decussates at the same level.
    2. Fasciculus gracilis ascends ipsilateral and decussates at the level of spinal cord.
    3. Cerebellar nuclei are the main relay center for sensory information carried by the dorsal column.
    4. Pain and temperature are the main sensations perceived by dorsal column.
    5. Fasciculus cuneatus provides motor innervation to the upper extremities.
