Histologie spéciale et des animaux domestiques [ LVETE1390 ]

Concepts of animal cell biology (VET1295), anatomy of domestic animals (LVET1241), general histology (LBIO1232A) and immunology (LBIO1335).

Within the body, the different tissues are composed of specific structures and specialized cells that assemble to form organs, which will ultimately participate to the major functional systems of the animal. In this course, we will study in detail the morphological and functional characteristics of the main functional systems of the body, namely the cardiovascular, integumentary, lymphatic, digestive, respiratory, urinary, reproductive and endocrine systems. We will also tackle the central nervous system and the senses organs.

This course is built upon and extends the concepts acquired in the course of 'general histology' (LBIO1232A). It is aimed to provide veterinary students with a panorama of organs' histology and functions in correlation with the course of 'animal physiology'. The emphasis is put on the histology of domestic animals and on comparative aspects among different species. The histological analysis is more or less detailed according to the importance of the physiological and biochemical processes which take place in the studied tissue, and depending on the clinical and pathological significance of the system.

Theoretical concepts are evaluated during an oral examination by two opened questions concerning two different systems studied in the course. The evaluation of histological sections takes place the same day and is also an oral examination. Using a light microscope, the student will have to identify and characterize cells, tissues and organs on similar histological preparations as those observed during the practical exercises.

The teaching involved ex cathedra lectures using powerpoint presentations  and blackboard drawings, illustrating the different studied systems with photomicrographs of histological sections and with diagrams.

During practical exercises, histological sections of the different organs envisaged in the lectures are available to students for analysis on light microscope, in order to observe the key features of cells and tissues and their assemblage into organs.

Each session of practical exercises begins with an evaluation of the concepts studied in the previous session, and this evaluation is included in the final note.
