Physiology 1 for Dentistry Students

Thematik

The most important mission of the Physiology Course in dentistry education is to familiarize students with the attributes of healthy functions of the living organism.

While acquiring knowledge about the most important functional characteristics of the human body the students can rely on their prior studies in biology, biophysics, chemistry-biochemistry and anatomy.

During the semester we introduce the most important elements of functioning of the organs and organ systems, as well as their cooperation also required to adapting to the environment, and the factors affecting these processes.

Special emphasis is placed on the neural and humoral regulatory processes of these life-functions, which are vital to maintain and preserve the homeostasis of the organism.

With the transfer of all this knowledge we would like to mould a holistic attitude and thinking of students, which will enable them to better understand the functions of the now healthy, however, later dysfunctional human organism.

Students with bonus points are not required to take the oral lab report on the 14th week. If the student has missed between 15 and 25% of the practical classes, an additional test question will be asked in the oral report.

Semesteranforderungen
