peripheral nervous system
5 multiple choice 1 point
which of the following is an example of a degenerative disease of the nervous system?

parkinsons disease

Explanation:

Question 4

To solve this, we analyze each option:

• Parasympathetic nervous system: Part of the autonomic nervous system, controls involuntary functions (e.g., digestion), not matching the description.
• Somatic nervous system: Controls voluntary movements and sensory input, but does not include all nerves extending from brain, spinal cord, and sensory receptors in the way described.
• Central nervous system: Consists of the brain and spinal cord only, not the nerves extending from them.
• Peripheral nervous system: Includes all nerves that extend from the central nervous system (brain, spinal cord) to the rest of the body, including sensory receptors. This matches the description.

To solve this, we analyze each option:

• Epilepsy: A neurological disorder characterized by seizures, not a degenerative disease (degenerative diseases involve progressive loss of structure/function of cells/tissues).
• Meningitis: An inflammation of the meninges (membranes around brain/spinal cord), usually caused by infection, not degenerative.
• Paralysis: A loss of muscle function, often due to injury or other causes, not a degenerative disease of the nervous system.
• Parkinson’s disease: A degenerative disease of the nervous system, characterized by progressive loss of dopamine - producing neurons in the brain, leading to motor and non - motor symptoms.

Answer:

D. peripheral nervous system
