Lesson No 13

Theme: Nasal cavity, larynx. Trachea, bronchi, lungs

Aim: To learn a structure, topography and larynx function. To learn to find, name and show the cartilages, muscles, joints and parts of larynx. During phylogenesis a diffusive breathing transforms by skin breathing and later - by branchiate breathing, and finally - by pulmonary breathing. Dirtying of outer environment and smoking affects badly to pulmonary breathing. That's why physical training, hygiene of work and housing workplaces have a considerable role in diseases prophylaxy of respiratory system (sharp respirator infections, sharp and chronic bronchitises, bronchial asthma, asthmatic status). Lungs open for influence of external environment, and so the respirator diseases are a serious problem for society.

To study structure, topography and function of pleura and its sheets. To study anatomy of medastnum and morphological-functional links between medastnum organs.

The professional orientation.

A physician have to know the structure and cooperation different larynx elements during breathing and forming of voice and sounds. Different factors of external and internal environment (infection, smoke, dust, surplus voice rise can entail the various larynx diseases (as sharp, so and chronic). That needs specific cure and (in many cases) immediate medical intervention. That's why such important there are knowledges of larynx anatomy.

Disease of lungs (tuberculosis, pneumonia, tumour), and also cardiac insufficiency, liver cirrhosis, pancriatitis, the rheumatic diseases and oth. can be causes of pleura lesion, which have a name pleurisy. Knowledge of the lungs and pleura topography in norm helps to determine diseases, which change the auscultation and percussion pictures. There are very actually for practical doctor.

There are many vitally importance organs in medastnum (heart, grate vessels, nerves, lymphatic nodes, trachea and bronchus, esophagus). These organs are nearly one to other, thus the illness of one organs provocative the illness of other. That is why knowledge of topography and interrelation between organs is important for practical.
