5.1. Methodological overview

The learning process designed for this course is based in the following aspects:

The course is structured as follows:

   - 40 hours of interactive lectures

   - 32 hours of laboratory sessions

   - 12 hours of seminars.

Students will find materials for each lesson at least one week before their beginning in the ADD, so as they can revise them in detail before each lecture.

Laboratory practices will be held in sessions of 2 hours for each group of 12 students. Practical classes will be evaluated within the final exam and through continuous evaluation in the lab. Students will prepare a written report with the main results obtained during laboratory sessions.

Seminars in Cell Biology will deepen about Cell Biology tools or alterations in different cell components or functions related to pathology. In Histology, students will discuss about different optical and electron micrographs obtained from histological preparations.

5.2. Learning tasks

In order to help students to obtain the expected results, the course's program includes the following activities:

MASTER CLASSES (40 hours):

The theoretical contents of the subject will be taught in the master classes. The classes are participatory and are structured in 11 lessons of Cell Biology and 26 lessons of Histology.

LABORATORY CLASSES (12 hours)

The practical classes will be carried out in the laboratory and in the microscopy room and will be distributed as follows: 8 hours correspond to Cell Biology area and 24 hours to Histology. In these practical sessions, the students will learn to use the light microscope to observe different cellular structures and to study histological preparations obtained from different tissues.

SEMINARS

In Cell Biology, the students will expose a work in which they will explain in depth some Cell Biology tools or in which they will study the relationship between defects in cell composition or function and pathology.

In Histology, the seminars will consist in the discussion about optical and electron micrographs of histological preparations related to lessons previously studied.
