Prerequisites

There are no prerequisites for taking the core subject of Cell Biology as it is a subject in the first semester of the first year. However, in order to ensure proper follow-up and the achievement of the learning objectives set out, it is recommended that students have a basic general knowledge of the structure, chemical composition and functions of the cells.

In addition, students should have good knowledge of English because many of the sources of information on this subject are in this language.


Objectives and Contextualisation

The subject of Cell Biology is attended to the first year of the Degree of Medicine, corresponding to a preclinical period, where students must obtain solid knowledge about the structural organization, functioning and regulation of the cells, Eukaryotic cells.

These basic skills are complemented with other basic and compulsory subjects in the Plan of Studies such as Biochemistry, Human genetics, Histology and Physiology, which will provide the student with a good understanding of the structural and functional organization of the human organism in the normal state (non-pathological).

On the other hand, the theoretical knowledge acquired in the subject of Cell Biology is complemented by practical training in the laboratory that allows students to introduce the techniques of study of the somatic and germinal cells, in a state of rest or division as well as of the observation of the cellular ultrastructure.

 

The formative objective of Cell Biology is that the students at the end of the subject are able to:

- Recognize the main differences between prokaryotic and eukaryotic cells

- Describe the structure, chemical composition and main functions of cell membranes

- Explain the processes of transport through the cell membranes

 

- Describe the organization and chemical composition of other elements of the cell surface

- Describe the structure, chemical composition and functions of the different cell compartments

- Explain the structure, chemical composition and functions of mitochondria and peroxisomes

- Describe the role of the cytosol

- Describe the structure, chemical composition and functions of the nuclear envelope and chromatin.

- Recognize the basic mechanisms of nuclear activity: replication and transcription

- List the different components of the cytoskeleton and describe its composition and structure

- Explain the contribution of the cytoskeleton in the formation of tissues

- Identify the molecules that participate in the control of the regulation of the cell cycle

- Describe the mechanisms involved in cell death for necrosis and apoptosis

- List and describe the different phases of the mitotic and myosic cell division and compare the two types of cell divisions

- Describe the process of male and female gametogenesis and compare the two types of processes

- Explain the Fertilization process

- Use properly the scientific terminology used in the field of Cell Biology

Evaluation Model

The evaluation of the subject will be based on the theoretical and practical syllabus that consists in the Program of the same. The achievement of the objectives and the acquisition of the competences described in the previous sections will be assessed, both those associated with the theoretical concepts expressed in the blocks and those associated with seminars and practices (laboratory and classroom).

Continuous evaluation:

The subject will be evaluated continuously during the course through two partial tests (P1 and  P2) eliminatory of subject plus three activities or tests that will evaluate the content of the  sessions of laboratory practices (S1, S2, S3), and a test that will evaluate the  contents of the microscopy seminar (SEM). Each of the two partial tests will be done through an objective exam with multiple choice items, aimed at demonstrating the acquisition of competences and the integration of theoretical and practical learning. It will consist of multiple choice questions with 4 answers, of which 1, 2 or 3 can be true. Wrong answers will be proportionately subtracted.

The contents that will be evaluated in P1 are: i) Theory of the first topics (from A to D  and cytosol) (32%) and ii) the first two classroom practices (5%)

The contents that will be evaluated in P2 are: i) Theory of the last topics (from E, except Cytosol, to I) (38%) and ii) classroom practices 3 and 4 (5%).

The tests or activities that will be carried out in the S1, S2 and S3 of laboratory practices and in the SEM will evaluate the participation and knowledge acquired in each of these sessions. The activities or tests will be related to the activity carried out.

The partial tests P1 and P2 will be done on the days indicated by the Faculty, in the classrooms indicated. The activities or tests of S1, S2, S3 and SEM will be done in the same practice laboratory (for S1, S2 and S3) or in the seminar room (for SEM), at the end of each of the sessions and are not recoverable. Each of the tests and activities described in the previous paragraph will have the following weighting in the final grade of the subject:

P1 (37%) + P2 (43%) + S1(5%) + S2 (5%) + S3 (5%) + SEM (5%)

To pass the subject, the following requirements must be met: i) that the two grades obtained in P1  and  P2 are  equal  to  or greater than 5  and ii) that the weighted average of P1+P2+S1+S2+S3+SEM is equal to  or greater than5 out of 10.

Attention: attendance at laboratory practice sessions is mandatory for students enrolled for the first time in this subject and who follow the continuous assessment model. Repeating students of course 22-23 who have a grade higher than 5 in tests S2 and S3 are not obliged to do them and the mark obtained the previous course is saved.

Final test of recovery:

In the case of not passing the subject through continuous assessment, there will be a final evaluation of recovery of the partial tests with a grade lower than 5, mandatory to make average. Students with partial tests with a grade greater than 5 can also take the recovery exam in order to try to raise the grade of the partial or partials they consider. To do this, they must request it sufficiently in advance from the coordinator of the subject. The grade previously obtained in the continuous evaluation will be replaced by the grade obtained in the recovery exam

In order to participate in the recovery test, two requirements must be met: i) have submitted to the two partial tests P1 and P2  and ii) that  the weighted average mark of the continuous evaluation (P1(37%)+P2(48%)+S1(5%)+S2 (5%)+S3 (5%)+SEM(5%)) is equal to or greater than 2.5.

The recovery exam will consist of two parts:

The first part (37% of the final grade) is an objective test that corresponds to the contents of P1, and therefore evaluates the following contents: i) Theory of the first topics (from A to D  and cytosol) (32%) and ii) the first two classroom practices (5%).

The second part (48% of the final grade) is an objective test that corresponds to the contents of P2, and therefore evaluates the following contents: i) Theory (38%) of the last topics (from E, except Cytosol, to I) and ii) classroom practices 3 and 4 (5%).

Students who have passed one of the two partials with a grade equal to or greater than 5 will be able to examine only the corresponding part of the suspended partial, without also having to submit to the partial that they have already approved.

The final grade of recovery of the subject will be  the sum of the weighted grade of the recovery exam plus the weighted notes of the two practice tests. In case a student has passed a partial, the grade obtained during the continuous assessment, corresponding weighted, will be taken into account for the calculation of the final grade of the recovery exam.

The day and time of the revisions of the partial exams and the recovery exam will be announced immediately upon the publication of the notes.

Exam review procedure:

Students may submit claims to the statement of the questions during the two days following the completion of the face-to-face exams.

The day and time of the revisions of the partial exams and the recovery exam will be announced immediately upon the publication of the notes.

 

ATTENTION: Student's assessment may experience some modifications depending on events outside the universitythat may affect face-to-face learning.

 

Examination-based evaluation:

Students can enter the single assessment system, according to the regulations of the Faculty. Single assessment will be based on the content of the subject's programme, the acquisition of the same competences, and will have the same level of demand as continuous assessment.

Single assessment consists of examinations carried out on the same date as the second partial of the continuous assessment.

For the evaluation an exam will be carried out consisting of:

Theoretical knowledge

- multiple choice questions to evaluate the theoretical knowledge of the subject (blocks A-I) and the content of the PAUL, with a weighting of 80% of the overall grade.

Practical knowledge

- Multiple choice questions and / or restricted written questions of the concepts related to the laboratory and seminar practices, with a weighting of 20% of the overall grade.

To pass the subject, the following requirements must be met:

1. Have obtained a grade of 5.0 or higher in the exam that evaluates the theoretical knowledge of the subject.

2. That the weighted average of the marks obtained in the different exams carried out is equal to or greater than 5.0.

The student who does not attend the scheduled global and recovery exams will be considered as "not evaluable".


Retake exam. The same recovery system will be applied as for continuous assessment.

The review of the qualifications will follow the same procedure as for the continuous assessment.
