What term describes the loss of reflex functions below the level of a spinal cord injury?

• A. Paresis
• B. Spinal shock
• C. Neurogenic shock
• D. Hyporeflexia

Answer: (B)

The term that describes the loss of reflex functions below the level of a spinal cord injury is spinal shock. Spinal shock refers to the transient physiological condition following a spinal cord injury, which typically involves a period of areflexia (loss of reflexes) and flaccid paralysis below the injury level. This state can lead to the absence of reflex activities, even in response to stimuli because the neural pathways have been disrupted by the injury.

Spinal shock interferes with normal spinal reflexes, which can result in temporary loss of all sensory and motor functions below the level of the injury until the spinal cord begins to recover and reflex activity may return. This process can last for days to weeks. Eventually, as spinal shock resolves, some reflexes might return, although they may not be consistent or indicative of regained function.

Other terms provided do not capture this specific loss of reflexes in the same way. Paresis refers to weakness or partial loss of movement, while neurogenic shock involves a reduction in blood pressure and changes in heart rate due to the loss of sympathetic nervous system activity following a severe injury. Hyporeflexia indicates a decrease in reflexes but does not encompass the broader physiological changes and transient nature of the condition seen in spinal
