00358 - Histology

Learning outcomes

At the end of the course, students will have a preparation that allows them to understand the morpho-functional bases of the organization of the systems of the human body, with particular regard to the stomatognathic system. In particular, students will be able to: • know and use the instruments for microscopic observation; • recognize the microscopic organization of the eucharyotic cell; • know the differentiation mechanisms that lead to the formation of embryonic layers; • identify the organization of the various classes of tissues; • recognize the organization and functional characteristics of the mucous membranes of the oral cavity and salivary glands; • know the development and physiological evolution of dental tissues; • possess the basis for the interpretation of the physio-pathological processes that concern the stomatognathic system; • coordinate knowledge of basic disciplines to recognize the cellular and tissue bases of pathological processes.

Course contents

In order to optimize the learning experience, the following prerequisites are recommended: basic concepts of cell biology

 

GENERAL HISTOLOGY

Histogenesis, stem cells and differentiation

General organization of the human tissues: classification and general characteristics

Epithelial tissues: characteristics and classification. Lining epithelia: classification and morpho-functional aspects. Exocrine and endocrine glandular epithelia and secretory system: classification and morpho-functional aspects

Tissues of mesenchymal origin: embryonic connective tissue or mesenchyme. Adult proper connective tissue. Adipose tissue. Trophic and fluid connective tissues: blood cells, plasma and hematopoietic tissue, notes on the mechanisms of hematopoiesis. Lymphoid tissue: notes on cells and organs of the lymphatic system

Supporting connective tissues: cartilage: organization, cells and extracellular matrix. Bone: organization and classification, cells and extracellular matrix, mineralization of the matrix and bone remodeling.

Muscle tissues: classification and morpho-functional aspects of skeletal, cardiac, and smooth muscle tissue

Nervous tissue: neurons and glial cells. Organization of central nervous system and peripheral nervous system. Axon, synapse structure and myelin sheath. Morpho-functional aspects of glial cells

 

ODONTOSTOMATOLOGIC HISTOLOGY AND EMBRYOLOGY

Craniofacial development and growth

Odontogenesis - Dentinogenesis – Amelogenesis

Dental tissues: enamel, dentin, cement, pulp

Periodontium: gingiva, oral epithelium, periodontal ligament, alveolar bone

Tooth Eruption

Oral Mucosa

Salivary Glands

A laboratory experience to directly observe histologic slides will be carried out

Readings/Bibliography

Embriologia e Istologia del cavo orale - Miör Fejerskov - Edi Ermes

Wheater - Istologia ed Anatomia microscopica - Edra

Istologia - Monesi - Piccin

Istologia Umana - Idelson Gnocchi

Istologia per le Lauree Triennali e Magistrali - Idelson Gnocchi

Students will be strongly encouraged to take an independent approach to learning, using online resources

Teaching materials will be available online as downloadable content from the "Virtuale" platform, accessing the academic year of attendance

Teaching methods

Frontal lectures and Laboratory work experience in Histology Lab

In consideration of the types of activities and teaching methods adopted, all students (including all the international incoming exchange students, i.e. ERASMUS) must attend Module 1 and 2 online

Assessment methods

The Module is integrated with the Human Anatomy, Biochemistry, Applied Biology and Molecular Biology Courses. The final evaluation takes into account the grades of the entire Integrated Course, weighted average

 

Oral examination aiming to verify the students' ability to apply their knowledge and make the necessary logical-deductive connections, focusing on achieving the learning objectives, specifically related to general histology and odontostomatologic histology and embryology

The oral examination will be based on at least two topics among all contents covered during the course, including the laboratory section

The exam will be considered sufficient with a score ranging from 18/30 to 30/30, according to the following scheme:

Lack of preparation, serious and repeated conceptual errors → <18

Preparation on a very limited number of topics and analytical skills that emerge only with the help of the teacher, expressed in an overall correct language → 18-19

Preparation on a limited number of topics and ability to perform autonomous analysis only on purely executive matters, expression in correct language → 20-24

Preparation on a large number of topics, ability to make independent choices of critical analysis, mastery of specific terminology → 25-29

Exhaustive preparation on the topics, ability to make autonomous choices of critical analysis and connection, full mastery of specific terminology, and ability to argue and self-reflection → 30-30L (honors will be added in case of outstanding preparation)

 

To access the exam, online booking on Almaesami before the exam is mandatory

 

For students with learning disabilities (LD) or temporary or permanent disabilities: we recommend contacting the competent university office promptly; they will be responsible for suggesting any specific adaptation. All issues must, however, be submitted 15 days in advance for approval by the instructors, who will evaluate the appropriateness of the request, also taking into account the educational objectives of the course

 

Regarding learning assessment, the use of AI is prohibited. Any such use constitutes a violation of academic integrity

Teaching tools

- PowerPoint Presentations

- Video Presentations

- Histology Slides

PowerPoint and video presentations will be available online as downloadable content from the "Virtuale" platform, accessing the academic year of attendance
