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 and acquire, and use your creativity in interpretation of results of scientific projects, multidisciplinary components that histological or embryological.

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.

The 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 a Published Paper (up to 20 points); 

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

The final classification is the following weighted average of 4 components:

Theoretical Exam x 0.40 + Practical Exam x 0.40 + Paper Presentation x 0.15 + Participation x 0.05

Participation, which rewards attendance, the level of commitment, and even the quality of performance of each student during the lessons.

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

The student will be approved to the course unit if he obtains a minimum of 9.50 values, after applying the aforementioned formula.

Examinations or Special Assignments

PROJECT

[IN GROUPS OF 2 STUDENTS AND IF SOMEONE IS UNPAIRED ONE HAS 3 PERSONS]

Critical presentation of one (1) scientific article (original and not review) that includes a component of Histology and / or Embryology. The same will be done in the form of a commented PowerPoint presentation and video, made in Panopto.

The duration of each presentation is up to 2 minutes, with each student taking up to 1 minute and not less than 55 seconds. In case there must be 3 students the total time and up to 3 minutes, each person does not intervene for less than 55 sec.

Students who make presentations in English will have a bonus of up to 25% in the grade of the Article (that is, up to 5 more out of 20).

Delivery will be via Moodle, up to the deadline set by the conductor. Delivery after the end of the period will not be considered, being assigned a score of 0 points.

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 the course, the student may apply for grade improvement.

The student may eventually make improvements to only one of the tests, the theoretical or practical; the coordinator always takes the best combination of the best grades obtained at different times. The improvement process for the articles implies that the student return to integrate into a new working group (of a next school year). After approval can not improve "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 ANY SURVEY OF REGISTRATION THAT THE COORDINATOR MAY IMPLEMENT.
