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.
It can cause paralysis including paralysis of the muscles need for respiration.
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.
poliomyelitis
Poliovirus is a virus that affects the muscles and can cause paralysis. It primarily spreads through person-to-person contact and can infect the nervous system, leading to muscle weakness or paralysis, particularly in the legs. Vaccination has led to a significant reduction in the number of polio cases globally.
Neurotoxins like botulinum toxin block the release of acetylcholine, a neurotransmitter necessary for muscle contraction, leading to muscle paralysis. Tetanus toxin, on the other hand, inhibits the release of inhibitory neurotransmitters, causing muscles to contract uncontrollably. Both toxins disrupt normal nervous stimulation of the muscular system, resulting in paralysis or spasms.
The nervous system activates the muscles of the respiratory system (ribcage muscles and diaphragm) to cause breathing, so as to bring in oxygen and discard carbon dioxide.
Polio is a disease caused by the poliovirus. In its most severe form polio causes paralysis of the muscles of the legs, arms, and respiratory system.
Skeletal muscle contraction is activated by motor neurons in the spinal cord, which are themselves under control from motor neurons in the brain. Without nervous input, the muscles wont respond to volitional control.
The Respiratory System regulates breathing and gas exchanges within an organism. In humans, this system includes the lungs, airways, and respiratory muscles.
Two facts about the respiratory system include:it must work with both the nervous system and muscular systemillness, conditions, or injury to the muscles of respiration or the brain can interfere with the respiratory system's normal functioning
cycloplegia
Yes, a viral disease that destroys the neuron cell bodies in the anterior gray horn of the spinal cord can lead to muscle weakness or paralysis. The anterior gray horn is responsible for sending signals to the muscles, and if these neurons are destroyed, the muscles will not receive the necessary signals to contract properly, resulting in weakness or paralysis.
