Lesson No 18 (6 hours)

Theme. Anatomy of endocrine system organs. Anatomy of immune system organs. Practical skills on respiratory, urinary, reproductive and endocrine organs preparations.


Am: Study the structural and topographical peculartes of endocrne and immune organs. To study structure, topography and function of thymus, spleen, thyroid and parathyroid glands, endocrne part of tests and ovaries. Make a pont about the role of suprarenal glands and chromaphne organs n humoral regulaton of functons.


Professonal motivation. Practcal knowledge ncludes showng and demonstratng parts of organs n anatomcal preparatons. Study the structure, topography urnary and reproductve organs s necessary for wde range of therapy, surgery specalsts. Knowledge about anatomy of suprarenal glands and chromaphne organs, endocrne part of tests and ovary are the base for physology and clnc endocrnology. The anatomcal structure of stomach and spleen and physologcal processes, whch are takng place n these organs, gves a possblty for physcans to dagnose tmely and to treat recprocally n pathology. Ths knowledge s necessary for theropentst, surgeon, oncologst, haematologst. Thyroid and parathyroid glands have an influence on metabolism and calcium-phosphorus exchange of bony tissue and blood. Thymus is a centre organ of immune system. There are many modern diseases which based on structural and functional infringement of these endocrine glands.
