Which response relates to anterior cord syndrome?

The correct response highlights the characteristic features of anterior cord syndrome, which typically involves motor function deficits below the level of injury, while sparing the pathways responsible for fine touch and proprioceptive sensations. Anterior cord syndrome occurs due to damage to the anterior part of the spinal cord, which affects the corticospinal tracts leading to motor loss (paralysis or weakness) in the affected areas.

Preservation of fine touch and proprioception is an important aspect of this syndrome. This is because these sensory modalities are transmitted via the dorsal columns, which remain intact in anterior cord syndrome, while the anterior portion, where motor pathways reside, is compromised.

In this context, other options are not representative of anterior cord syndrome. For instance, loss of proprioception and vibration sensation typically suggests a dorsal column injury rather than anterior cord syndrome. Similarly, although there can be varying degrees of weakness in both upper and lower extremities, anterior cord syndrome does not specifically denote a greater weakness in lower versus upper extremities; such a distinction is more aligned with certain other types of spinal cord injuries. Lastly, areflexia in the lower limbs does not specifically define the syndrome, as reflex activity may still be present depending on the extent and location of the injury within the
