Question at position 4 Which of these is TRUE about ALS (Amyotrophic Lateral Sclerosis)?It is caused by the poliovirusIt is due to loss of dorsal motor neuronsIt is due to loss of dorsal sensory neuronsIt is due to loss of ventral sensory neuronsIt is due to loss of ventral motor neurons

BlackTom AI · Accepted Answer

The question asks which statement is true about ALS (Amyotrophic Lateral Sclerosis).
Option 1: 'It is caused by the poliovirus' — This is incorrect. ALS is a neurodegenerative condition not caused by poliovirus infection; poliovirus primarily affects motor neurons in the anterior horn but ALS is a distinct, progressive degenerative disease with multifactorial causes.
Option 2: 'It is due to loss of dorsal motor neurons' — This is inaccurate. ALS predominantly involves the loss of motor neurons in the ventral (anterior) horn of the spinal cord and motor cortex; dorsal motor neurons are not the primary cells affected in ALS.
Option 3: 'It is due to loss of dorsal sensory neurons' — This is also incorrect. ALS primarily targets motor neurons, not dorsal sensory neurons; sensory pathways are typically preserved initially in ALS.
Option 4: 'It is due to loss of ventral sensory neurons' — This statement is false. Ventral sensory neurons are not the characteristic pathology of ALS; the disease targets motor neurons, not sensory neurons.
Option 5: 'It is due to loss of ventral motor neurons' — This is correct. ALS involves degeneration and loss of ventral (anterior) horn motor neurons and corticospinal motor pathways, leading to muscle weakness and atrophy.
