Show Answer
Correct Answer – B
Answer: B – Contralateral loss of pain sensations
If the spinal cord is completely transected – All the sensations and motor functions distal to segment of transection are blocked.
Transection of spinal cord on single side results in “Brown Sequard Syndrome”
Functions affected:
| Function affected |
Position | Description |
| Motor | Ipsilateral side | Complete loss of motor functions below the level of transection |
| Sensory | Combined effects observed |
Some sensory functions are lost on transected side and others on opposite side. |
| On the Contralateral side: Sensation of pain, cold, & heat |
Result of disturbance in Spinothalamic pathway. Loss observed 2 to 6 segments below the level of transection. |

| Discrete Crude touch |
