Final answer:
The order of blockade by local anaethetics is Pain, temperature, sympathetic, proprioception, and touch.
The correct option is 3.
Step-by-step explanation:
Local anesthetics typically block nerve conduction by following a specific order. They first affect pain fibers, followed by temperature sensation, then sympathetic fibers, proprioception, and finally touch sensation.
1.Incorrect: This sequence doesn’t align with the usual order of blockade by local anesthetics.
2.Incorrect: The order listed here doesn’t match the typical sequence of blockade by local anesthetics.
3.Correct: This option correctly lists the order of blockade: pain, temperature, sympathetic, proprioception, and touch.
4.Incorrect: The order provided here is not in line with the typical sequence of blockade by local anesthetics.
So, the correct option is 3.
