Objectives

Provide theoretical and practical knowledge about the structure of cells, tissues and organs, the level of microscopy, especially optical, and when opportune also electronic, and on their histophysiology. Thus, the bases of knowledge and skills promoted to a better understanding of Anatomy, Physiology, Biochemistry, Immunology, Pathology, etc.. The practical component is based on the study of preparations of normal tissues and organs, subject directly to the optical microscope or indirectly, via his pictures taken by digital means.

It is also intended to demonstrate the importance of knowing and applying the normal histology of tissues and organs in the face of potential modifications of the same, as well as encourage students to make a morphofunctional integration of acquired knowledge and acquire.

Finally, if time allows, we aim to teach bases embryology general (descriptive and developmental biology) as well as simpler model organisms (invertebrates) that allow students to not only understand their importance as access and understand, then, embryology and general special organimos complex (vertebrates).

Learning outcomes and competences

Acquire solid theoretical knowledge on histology and embryology compared, giving access and understand more complex knowledge to acquire the degree or more advanced courses of study.

Having the ability to observe systematically describe the microscope and diagnose or before histological images, tissues and organs of vertebrates (fish to mammals), as well as to know foresee / histophysiology correlate its structural features from dyeing.

It is intended that students contact with basic principles of developmental biology and an overview of embryological development in comparative terms, integrating this knowledge with the systematic anatomy and microanatomy of the adult. It is also intended that students have the ability to discern the possible events that may cause teratological cases.

It also demonstrates the importance of knowing and applying the histology of normal tissue and organs against potential modifications thereof. To stimulate students to make a morphofunctional integration of acquired knowledge.

Eligibility for exams

In accordance with current regulations (see UPorto and ICBAS Rules), in particular, you must attend 3/4 of all practical classes taught.

Theoretical presentations will be taken into consideration only for the eventual assessment of the participation grade (see Final Grade Calculation).

Calculation formula of final grade

Formative Assessment:

Students are offered weekly exercises to help them monitor the progress of the classes and the individual level of learning. The teachers offer the solutions of the distributed exercises.

Summative assessment (each grade is given in the scale of 0-20) includes:

1. Final theoretical exam (minimum score = 9.50 / 20 points);

2. Final practical exam (minimum score = 9.50 / 20 points);

3. Preparation and Presentation of Project  (up to 20 points);

4. Engagement in Classes (up to 20 points).

The final classification is obtained via the following weighted average:

Theoretical Exam Grade x 0.40 + Practical Exam Grade x 0.40 + Test Grade x 0.15 + Participation Grade x 0.05

The “Participation” rewards attendance and punctuality, the level of commitment, and also the quality of performance of each student throughout the classes, especially in the practical ones.

The “Test” will consist of 3 moments of continuous theoretical assessment, in the form of multiple-choice mini-tests, lasting a few minutes each, to be carried out in the 3rd, 5th and 7th week of classes. In case of non-attendance to the mini-test, whatever the reason, the classification will be 0 values in this mini-test (it is not subject to repetition).

The student will be approved if he/she can get the minimum value of 9.50, after applying the above formula and if he/she has obtained frequency.

Note: The grades previously obtained by students will be taken into account in the current academic year, but will be subject to the evaluation formula to be applied in the current academic year. THe Project made in the previous schoolar year(s) corresponds to the Test of the present schoolar year.

Note 2: the Practical exam may contain theoretical-practical correlation and integration questions.

Special assessment (TE, DA, ...)

Special examination will be available to all students who have legally entitled to it, on a date to be announced by the Regent, in accordance with the practice in force in ICBAS. Note however that any particular exae (T or TP) can be of a different nature from that applied in normal time or resource (eg, having a lower extension may be oral character, etc.).

Classification improvement

After approval to a discipline, the student can attempt to improve its first grade. Eventually, the student can attempt to improve the previous mark of just one of the exams, either the theory or the practical exam. The responsible will consider the best possible combination of grades. For improvement of the Project, the student must be integrated again in a new working group (of a new school year). After approval, there is no possibility to improve the "Participation".

Observations

If the student does not get final approval in a given school year, the grades achieved in the various partial evaluation components may transit times to and / or following school years, a situation that must be confirmed with the conductor at the beginning of each school year.

However, the Regent reserves the right not to take previous effort where there is no possibility of recovery, given the changes taking place in the type of course evaluation. If there is partial transport notes, the student is subject to the evaluation formula of the current school year.

At a certain time of examinations, the student graduates may choose to perform one final exam (the theoretical or theoretical-practical), BUT IT IS REQUIRED TO RESPOND TO AN EVENTUAL SURVEY FOR EXAM REGISTRATION.
