Objectives

Provide theoretical and practical knowledge about the structure of cells, tissues and organs, the level of microscopy, especially optical, but 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, and use your creativity in planning of multidisciplinary projects, to include a histological component.

Finally, 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 obtain the 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, and use your creativity in planning multidisciplinary projects that integrate histological component.

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 in theoretical classes will be taken into account for the purpose of adjusting 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 (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 test grade x 0.40 + Project Grade x 0.15 + Participation Grade x 0.05

The "Engagement" rewards attendance, punctuality, level of commitment, and even the quality of performance of each student during the lessons.

The "Project" may be subject to a bonus (see below).

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: As announced in each school year, ratings previously obtained by students will be taken into account in this school year, but will be subject to the assessment formula to be applied in this school year. Project done in previous school year, even if of another nature, will be taken into consideration.

Note 2: Students who do not submit their projects online until the time limit will have 0 values.

Examinations or Special Assignments

PROJECT (INDIVIDUAL WORK):

Elaboration and presentation of an Infographics (PNG, JPG, TIIF or PDF format) on a specific aspect that fits into the topic (s) covered in the UC Program.

Infographics must integrate histology and / or embryology components.

Infographics can be done in any program. Research and use of free resources available for this purpose is suggested (eg, https://www.canva.com/pt_pt/).

The presentation is made by a video picth with a maximum duration of 1 min, in which the student gives a brief explanation of his Infographics. The video should show the speaker speaking in the foreground, and not the Infographics (delivered in the format mentioned above). There may be a real or virtual background in the video behind the speaker, possibly connected to the theme.

"Self-filming" can be done through a system of the student's choice, using a mobile phone type device or video recording application / platform.

The work will be submitted through Moodle until the deadline defined by the conductor.

Students who do the infographics and their video presentation in English will have a bonus of up to 25% on the project grade (ie, up to 5 more out of 20). The writing of the project in English, but with an oral presentation in Portuguese, will have half the bonus.

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.
