Q1. The correct option is 3. The symptoms of Parkinson's disease include shaky walking, rigidity, slowness in the movement. Basal gamglia is connected with cerebral cortex, thalamus and are involved in various functions of motor movements, emotions, learning etc. Damage to basal ganglia leads to problems related to speech, movement.

Q2. The correct option is 8. The cell bodies of sensory neurons are located in dorsal root ganglion. These sensory neurons provide information regarding touch, temperature, pain and position located outside the CNS found in dorsal ganglia.

Q3. The correct option is 7. Because, The corticospinal tract carry movement related information from cerebral cortex to spinal cord via mid brain, pons and medulla.

Q4. The correct option is 3. Damage of basal ganglia causes diseases like Huntington and Parkinson diseases. Gradual degeneration of basal ganglia i.e. putamen and caudate nucleus causes Huntington disease

Q5. The correct option is 3. Apart from Supplementary motor complex, Premotor complex, Corticospinal tract that involve in movements,they are a part of cerebral cortex. Whereas cerebellum is not involved in initiating movements, Spinothalamic pathway transmits pain, touch and temperature to thalamus and Dorsal column pathway is also a sensory pathway that conveys fine touch, position and vibration from skin. Basal ganglia is involved in initiating the voluntary movements.

Q6. The correct option is 5. Parietal area of cerebral cortex processes sensory information that include pain, touch. Therefore, the paietal lobe is involved in interpreting the pain.
