One pоpulаr methоd оf murder, in mystery novels, is strychnine poisoning. Strychnine is а lethаl poison because it blocks the glycine receptors of the somatic motor neurons. The neurotransmitter glycine normally prevents excessive contractions of skeletal muscles. Strychnine disrupts the process thus allowing the motor neurons to generate impulses without restraint. As a result, all skeletal muscles remain fully contracted. The mystery in this case is, why are contracted skeletal muscles a detriment? After all, we do need contracted muscles in order to ventilate. Based on your knowledge of the mechanism of breathing:Explain, clearly, why fully contracted skeletal muscles, from the effect of strychnine on the nervous, would result in suffocation and death. Be sure to include in your explanation principles such as compliance, recoil, Gas laws, volume/ pressure relationships etc…
