Question

Which of the following is not a disease to related to the neural system?

• A. Parkinson's disease
• B. Meningitis
• C. Sciatica
• D. None of the above

Answer 1

The correct option is D None of the above

A.Parkinson's disease is a chronic progressive disorder of the nervous system characterized by major symptoms such as rigidity, bradykinesia(slowness of movement), tremor and postural instability(unstable while standing). Hence Parkinson's is a disorder of the neural system.
B.Meningitis is the inflammation of meninges(membrane) of the brain). It can be due to bacterial, viral or fungal infection. As meningitis is related to membranes of the brain it is a disorder of the neural system.
C.The sciatic nerve is the largest nerve in the body. It originates in a bundle of nerves in the lower back and passes through the pelvis and down the back of each thigh.
A pinched Sciatic nerve causes sciatica. Its symptoms include lower back pain that spreads through hip, to the back of the thigh, and down the inside of the back of leg via sciatic nerve., characterized by pain, tingling, numbness and weakness. As sciatica is related to sciatic nerve it is a disorder of the neural system.
So, the correct option is 'None of the above'.
