Question

1. which chronic condition destroys motor neurons?

○ cerebral palsy
○ huntington’s disease
○ amyotrophic lateral sclerosis
○ bell’s palsy

Explanation:

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease that specifically targets and destroys motor neurons. Motor neurons are responsible for transmitting signals from the brain and spinal cord to muscles, enabling movement. In ALS, the progressive loss of these neurons leads to muscle weakness, atrophy, and eventually paralysis.
Cerebral palsy is a group of disorders affecting movement and posture due to brain damage, not motor neuron destruction. Huntington's disease is caused by a genetic mutation leading to the degeneration of neurons in the brain, but not specifically motor neurons. Bell's palsy is a condition that causes temporary facial muscle weakness or paralysis due to damage to the facial nerve, not motor neurons in general.

Answer:

Amyotrophic lateral sclerosis
