Question

What organ in the muscular system does botulism affect?

Answer 1

Toxin of Clostridium botulinum actually disrupts nerve function; neurotransmitters are not secreted at neuromuscular junctions. Hence there is paralysis of muscles.

Explanation:

Effect of botulism starts in various muscles of eye: there is drooping of eyelid, and no movement of eye-ball. Mandibular muscles are also affected, so chewing, swallowing, talking, etc. become difficult. Despite all these symptoms, the victim remains conscious.

Weakness of limbs set in later. Respiratory muscles may get affected and the disease is fatal if left untreated.
