00358 - Histology

Learning outcomes

Upon completion of the course the student will have acquired a preparation that will allow him to understand the morpho-functional bases of the organization of the human body, with particular regard to the stomatognathic system. In particular, the student will be able to: • understand and use the instruments for a microscopic observation; • recognize the microscopic organization of the eukaryotic cell; • understand the differentiation mechanisms that lead to the formation of the embryonic sheets; • 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; • understand the development and physiological evolution of dental tissues; • interpret the physio-pathological processes concerning the stomatognathic apparatus; • coordinate the knowledge of the basic disciplines to recognize the cellular and tissue bases of pathological processes

Course contents

GENERAL HISTOLOGY

Histogenesis. Stem cells and differentiation.

General organization of the different 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

Cranio-facial development - Odontogenesis - Dentinogenesis – Amelogenesis – Dental tissues: enamel, dentin, cement, pulp - Periodontium: gingiva, oral epithelium, periodontal ligament, alveolar bone - Tooth Eruption - Oral Mucosa - Tongue - Salivary Glands.

Readings/Bibliography

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

Wheater - Istologia ed Anatomia microscopica - Edra

Istologia - Monesi - Piccin

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

Teaching methods

Lectures with extensive use of histology slides and video.

Assessment methods

Oral interview, whose result is graduated from 18/30 to 30/30. The minimum grade is achieved by a non-thorough knowledge of the subject, 19 to 25 for a fair knowledge, 26 to 29 for a good knowledge, while 30 represents a great knowledge and "cum laude" is added in case of excellence.

The result is integrated with the Human Anatomy Course. The final evaluation takes into account the grades of the entire Course.

Teaching tools

- PowerPoint Presentations

- Video Presentations
