Abstract
In our work we aimed to conduct a fundamental study of the process of morphological disorganization of the structural components of the mucous membrane and cartilage of the larynx at the end of the seventh day of experimental opioid effects at the microstructural level. This information in the future will allow to form a pathomorphological base, which will be used to compare the components of the mucous membrane and cartilage of the larynx in the norm with the dynamics of their changes as a result of experimental opioid effects at different times.
