Anatomy and human histology 3

Module Human histology

Knowledge and Understanding

The student will acquire the fundamental cytological and histological knowledge necessary to understand the general organization of higher eukaryotic cells, their structural and functional specializations, and the cellular interactions underlying the organization of tissues in the human body. They will understand the fundamental principles of histogenesis and the architecture of normal tissues, gaining an integrated view of the relationship between microscopic structure and function.

Ability to Apply Knowledge and Understanding

The student will be able to recognize and describe the morphological characteristics of the main cellular types and normal tissues of the human body, also through the observation and interpretation of histological specimens.

Autonomy of Judgment

The student will develop the ability to critically interpret the relationships between cellular structure, tissue organization, and function.

Communication Skills

The student will be able to clearly and accurately describe cellular and tissue structures, using appropriate scientific language and correct terminology in the fields of cytology and histology.

Learning Skills

The student will consolidate a study method aimed at integrating microscopic knowledge with subsequent preclinical and clinical disciplines, developing the ability to independently update and deepen their foundational knowledge of the organization of the human body.

Lectures.
If the course is delivered in a hybrid or remote format, necessary adjustments may be made to what was previously stated, in order to comply with the planned program as outlined in the syllabus.

Prerequisites as per the study program

Mandatory attendance.

Assessment Methods

The examination consists of an oral interview during which questions will cover the various topics included in the syllabus. The exam aims to assess:
i) the level of knowledge and understanding of the morphology of human tissues under physiological conditions;
ii) clarity of presentation;
iii) appropriate use of medical-scientific terminology.

Final Grade Criteria

The final grade will be assigned according to the following criteria:

29–30 with honors (30 cum laude):
The student demonstrates in-depth knowledge of the topics discussed during the examination, is able to promptly and correctly integrate and critically analyze the subjects addressed during the interview, and shows excellent communication skills with full command of medical-scientific terminology.

26–28:
The student demonstrates good knowledge of the topics discussed during the examination, is able to integrate and critically analyze the subjects in a coherent and logical manner, and presents the material clearly using appropriate medical-scientific terminology.

22–25:
The student demonstrates fair knowledge of the topics discussed during the examination, although mainly limited to the principal subjects; is able to integrate and critically analyze the topics, though not always in a fully coherent manner; and presents the material fairly clearly with adequate command of terminology.

18–21:
The student demonstrates the minimum required knowledge of the topics discussed during the examination, shows limited ability to integrate and critically analyze the subjects addressed, and presents the material in a sufficiently clear manner, although with limited command of appropriate terminology.

Fail:
The student does not possess the minimum required knowledge of the main course contents. The ability to use appropriate technical terminology is very poor or absent, and the student is unable to independently apply the acquired knowledge.

Assessment may also be conducted remotely (online), should circumstances require it.

The written exam consists of 30 to 60 multiple-choice questions.

1. Are the cells of cardiac tissue multinucleated?

2. Do exocrine glands secrete hormones?

3. What are the functions of leukocytes?

4. What shape do erythrocytes have?

5. Are neurons cells that continuously undergo mitotic division?

6. Do osteoclasts participate in the formation of bone tissue?

7. Is the myelin sheath found in microglia?

8. Is the red blood cell the largest cell in the human body?
