Methodical instruction for 1st
year students

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 med³ast³num
and morphological-functional links between med³ast³num
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 med³ast³num (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.
