1. C. Lateral spinothalmic.
The fibers of the lateral spinothalamic tract conduct information about temperature and pain.
2. B. Parkinson's disease.
Tremors, stooped gait called parkisonion gait, postural instability are the signs of Parkinson's disease.
3. D. Red nuclei.
Red nuclei also called nucleus ruber is 8nvolve din motor coordination.
4. C. Phrenic.
5. C. Femoral.
Major nerves of brachial plexus are;
Genitofemoral, obtrurator, lateral femoral and femoral.
