Explanation / Answer

Answer 28. Degeneration of dopamine neuron in the substantia nigra causes Parkinson's disease. Parkinson's disease is neurodegenerative disease caused due to degeneration of dopaminergic neurons in the substantia nigra. The symtoms include tremor, rigidity, difficulty in walking.

Answer 29. Alzeihmers disease, a progressive degenerative disease with dementia involves loss of acetylcholine neuron in the basal forebrain. Symtoms include cognitive changes, behaviour change, mental confusion, dementia, anger, depression, hallucinations etc.

Answer 30. Answer will be option c that is incorrect statement is the axons of the sensory neurons enter the spinal cord via ventral horn. It is incorrect because sensory nerve axons enter the spinal cord via dorsal horn and motor nerve exits from the ventral horn of the spinal cord.

Answer 31. The ventral portion of the spinal cord controls skeletal muscles movement. This is because the motor nerve exit from the ventral horn of the spinal cord which carry information to the skeletal muscle or effector organs for the movement of any other action to be taken.
