Objectives

In the continuation of the unit of Histology and Embryology Comparative I provide theoretical and practical knowledge about the structure of cells, tissues and organs (now in recent emphasis), the microscopic level, particularly optics, but sometimes at TEM level, and the respective 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, 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.

Finally, we aim to teach complementary bases of general and special embryology, now with emphasis on the latest, encompassing aspects of descriptive and developmental biology and studies aiming to model organisms (vertebrates). It is intended to provide students with knowledge to understand the structure and the normal organogenesis and placement of organs and tissues in the adult animal. It is also intended that students have the ability to discern the possible events that may cause teratological changes.

Learning outcomes and competences

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

It is intended that students obtain the basic principles of developmental biology and embryology descriptive, with 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.

Being aware of the importance of full implementation of whether the histology and embryology of normal tissues and organs in the face of potential changes therein. Enhance the student's ability to make a morphofunctional integration of acquired knowledge, and use your creativity in interpreting works that integrate histological component / embryological.

Increment of competence for the presentation and critical evaluation of issues related to Histology and Embryology Compared.

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.

Attendance at theoretical classes will be taken into account only for the assessment of the Participation grade (see Final Grade Calculation Formula).

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:

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 1: The classifications obtained previously 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 Paper Presenttion made in the previous academic year corresponds to the Test of the present academic 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 P) 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

Only after final approval of the curricular unit can the student request a grade improvement in the following period. You can improve only in final exams, theoretical and/or practical. The conductor will enjoy the best possible combination of notes. It is not possible to improve "Continuous Assessment Test" or "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.
