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), the student must attend at least 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. Continuous participation in classes (up to 20 points).

The final classification is obtained via the following weighted average:

Theoretical Exam Grade x 0.50 + Practical Exam Grade x 0.45 + Participation Grade x 0.05

“Participation” rewards attendance, punctuality, level of commitment, and also the quality of performance of each student throughout the practical and theoretical classes (there may be oral or written questions in class).

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: For re-enrolled students, the grades previously obtained in the Exam(s) and/or Participation component will be taken into account this academic year. However, taking into account the form of evaluation, project components or µ-tests from previous years will not be taken into account.

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 will the student be able to request a grade improvement in the following period. You will only be able to improve in final exams, theoretical and/or practical. The responsible will take advantage of the best possible combination of notes. After approval, it is not possible to improve "Participation".

Observations

The partial grades achieved in the previous year(s) in the exam components are carried over to the current academic year.

Previous effort will not be used in cases where there is no possibility of success, due to changes made to the type of assessment of the subject.

If grades are transferred, the student is subject to the assessment formula for the current academic year.

In a given exam period, the student may choose to take only one of the final exams (the theoretical or the practical), BUT HE/SHE IS OBLIGED TO RESPOND TO ANY EXAM REGISTRATION SURVEY.
