Probably because you can't breathe...
Paralysis of the limbs. In some cases, it can cause paralysis of the chest muscles making breathing difficult. It can even cause death.
Polio is a disease caused by a virus. It causes paralysis in the muscles. If it affects the muscles of the chest, it can prevent breathing and the individual suffocates.
paralysis of voluntary muscles, not involuntary muscles and tissues that control body functions
Poisonous hemlock contains a toxin called coniine, which disrupts the nervous system by blocking nerve signals. When ingested, coniine can lead to paralysis, including paralysis of the muscles used for breathing, ultimately causing death due to respiratory failure.
When the release of acetylcholine (ACh) is blocked, communication between nerve cells and muscles is disrupted, leading to muscle weakness or paralysis. This can cause symptoms such as difficulty moving, breathing, or swallowing, depending on which muscles are affected.
Poisons like botulism inhibit the release of acetylcholine, a neurotransmitter essential for muscle contraction. As a result, muscles would be unable to receive signals to contract, leading to paralysis. This paralysis can affect various muscles, including those involved in breathing, which can be life-threatening. Overall, the affected muscles would remain relaxed and unresponsive.
Respiratory paralysis is a condition in which the muscles responsible for breathing become weak or inactive, leading to an inability to breathe effectively. This can result from various causes, including neurological disorders, spinal cord injuries, or certain diseases that affect the respiratory muscles. As a consequence, individuals may require mechanical ventilation or other interventions to assist with breathing. Prompt medical attention is essential to manage the condition and prevent life-threatening complications.
It can cause paralysis including paralysis of the muscles need for respiration.
cycloplegia
These are diaphragm and externa intercostal muscles in quiet breathing and sternocliedomastoid ,sclene muscles,anterior serrati in heavy breathing
Bulbar polio involves the infection of the brainstem and medulla. It can lead to difficulty breathing, swallowing, and speaking due to paralysis of the muscles in these areas.
Botulism can cause facial muscle paralysis and problems with breathing. The botulinum toxins are very similar in structure and function to the tetanus toxin, but differ dramatically in their clinical effects because they target different cells in the nervous system. illness which begins by causing the paralysis of the face muscles and then the paralysis of most of the body.When the muscles which control breathing become paralyzed, this results in reparatory arrest and death.Botulinum toxin is the most powerful neurotoxin known to date. Only one single molecule of it is needed to stop one neuron working.Just one gram of botulinum toxin would be enough to kill 14,000 people (if ingested), 1.25 million people if inhaled, or a staggering 8.3 million people if injected.
