Teaching Plan Information

1.2. Recommendations to take this course

Basic knowledge of Anatomy, Biology, Chemistry and Biochemistry.

1.4. Activities and key dates

On the website of the Faculty of Veterinary Medicine (htpp://veterinaria.unizar.es/gradovet) you are offered detailed information about the different activities programmed for this course and the corresponding deadlines.

5.1. Methodological overview

The learning process that has been designed for this course is based on the following activities:

a) Lectures: The topics tackled in this course will be presented, explained and discussed in 50 minute lectures where ppt presentations will be used for image support.

b) Seminars: At the beginning of course a seminar will be held where the Histological Technique will be explained. Students will also observe, comment and discuss electron microscopy images corresponding to the theoretical classes of Cytology.

c) Laboratory practice: Parallel to the theory small-group practical classes will be held, where the student will observe histological preparations of various tissues and organs using optical microscopes. Each student must take 16 practices, 1.5 or 2 hour duration, in the Histology laboratory. The existence of more than 3 unexcused absences from these classes implies that the student will go directly to practical final exam.

d) Works: Students have to complete a lab notebook which is considered mandatory.

e) Tutorials: Students will be able to meet teachers to consult issues related to the subject.    Dates and times should be agreed by email in advance.

Selected supporting materials will be provided in the Moodle Digital Platform:
