CITOCHIMICA ED ISTOCHIMICA NEL DIFFERENZIAMENTO CELLULARE E TESSUTALE

Academic Year 2022/2023 - Teacher: MICHELINO DANIELE ANTONIO DI ROSA

Expected Learning Outcomes

The aim of the discipline is to provide students with the main knowledge concerning the regulatory mechanisms that characterize the different cell lines during differentiation into specialized tissue components and the main cytochemical and histochemical methods applied to them.

Course Structure

Frontal lessons.

If the teaching is given in a mixed or remote mode, the necessary changes may be introduced with respect to what was previously stated, in order to comply with the program envisaged and reported in the syllabus.

Learning Assessment

Learning Assessment Procedures

Oral examination

The oral examination consists of an interview in which questions will be asked that will focus on the different topics of the study program.

The test allows to verify:

i) the level of knowledge of human histology in physiological conditions of the organism.

ii) clarity of presentation.

iii) the property of medical-scientific language.

For the attribution of the final grade, the following parameters will be taken into account:

Grade 29-30 with honors: the student has a thorough knowledge of the topics discussed during the exam; he is able to promptly and correctly integrate and critically analyze the topics covered by the interview; he has excellent communication skills and masters medical-scientific language.

Grade 26-28: the student has a good knowledge of the topics discussed during the exam, he is able to integrate and analyze the topics covered by the interview in a critical and linear way and he presents the topics clearly using an appropriate medical-scientific language;

Grade 22-25: the student has a fair knowledge of the topics discussed during the exam, even if limited to the main topics; he manages to integrate and analyze in a critical but not always linear way the topics covered by the interview and he exposes the topics quite clearly with a discrete property of language;

Score 18-21: the student has minimal knowledge of the topics discussed during the exam, he has a modest ability to integrate and critically analyze the topics covered by the interview and he explains the topics in a sufficiently clear way although the language property is underdeveloped;

Failed exam: the student does not have the minimum required knowledge of the main teaching contents. The ability to use specific language is very little or absent and he is unable to independently apply the acquired knowledge.
