Prerequisites

Master the contents of the first semester Cell Biology program.

Objectives

This is a compulsory first-course subject that introduces students to the fundamentals of the tissue organization of vertebrates. The central goal of Histology is the study of the cellular organization that make animal tissues and their correlation with the tissue function. This subject has been designed assuming that the student has the basic knowledge of Cell Biology.

Specific objectives of the subject:

 

1. To know the diversity of animal cells broadly.
2. To know how to distinguish the cytophysiological characteristics that define the different animal tissues.

Learning outcomes

  • CM30 (Interpret clinical, histological, biochemical and molecular genetic data.) Interpret clinical, histological, biochemical and molecular genetic data.
  • CM31 (Deliver a public presentation on a biomedical topic.) Deliver a public presentation on a biomedical topic.
  • CM33 (Combine searches for new knowledge and problem-solving in biomedicine with ethical and social responsibility.) Combine searches for new knowledge and problem-solving in biomedicine with ethical and social responsibility.
  • KM32 (Identify different types of animal tissue and cells.) Identify different types of animal tissue and cells.
  • SM35 (Use histological, immunological and clinical laboratory techniques to study animal tissues and determine biochemical and genetic markers associated with different pathologies.)

Lectures

The theory program will be taught in 18 classes. They will be made using audiovisual material prepared by the teacher, material that students will have at their disposal in the Virtual Campus. Some of these theory classes will follow an inverted class pattern where students will have to prepare a material before class to debate in the classroom.

Seminars

The 4 scheduled seminars are designed so that students work in small groups, acquire group work abilities and critical reasoning. The students will be divided into groups of 4 to 6 to work on a specific topic of the program for the subsequent oral presentation and collective discussion. The organization of the groups and the distribution of topics to be discussed will take place during the first seminar.

In the remaining seminars, some groups of students will have to deliver an essay about the subject proposed by the teacher. The same groups of students will orally present the subject to the rest of the class with the means available in the classroom.

The bibliography that students can use, as well as the scientific work related to the topics, will be collected in the Virtual Campus. Attendance at the seminars is mandatory.

For this subject, the use of Artificial Intelligence (AI) technologies is permitted exclusively in support tasks, such as bibliographic or information searches, text correction or translations. The student must clearly identify which parts have been generated with this technology, specify the tools used and include a critical reflection on how these have influenced the process and the final result of the activity. The lack of transparency in the use of AI in this assessable activity will be considered a lack of academic honesty and may lead to a partial or total penalty in the grade of the activity, or greater sanctions in serious cases.

Tutorials

The tutorials will be carried out in a personalized way in the office of the professor (schedule to be agreed). Tutorials should be used to clarify concepts, establish the knowledge acquired and facilitate study by students. They can also be used to solve the doubts that students have about the preparation of the seminars.

Annotation: within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

Assessment

Continuous assessment activities

Title Weight Hours ECTS Learning outcomes
Inverted Class 15% 1 0.04 CM30, CM33, KM32, SM35
Final Test 50% 1 0.04 CM30, CM33, KM32, SM35
Seminars 35% 1 0.04 CM30, CM31, CM33, KM32, SM35

The competences of this subject will be evaluated by means of continuous evaluation, which will include different tests, written works and public presentation.

The evaluation system is organized in two sections, each of which is assessed independently and will be assigned a specific weight in the final qualification of the module:

Final Exam (50% of the overall grade): This section evaluates individually with tests of the knowledge obtained by each student. A test will be performed at the end of the contents of the Histology program. Students who have obtained a grade of less than 4 (out of 10) in this test will not be able to ponder it with the mark obtained in the seminars or the reversed class, and therefore, they will have to complete the recovery exam, which will be taken same characteristics as the final test.

The students who have passed may improve the grade obtained by presenting themselves to the recovery exam, with the benefit that the presentation to the examination of recovery implies the resignation of the qualification obtained previously.


Reversed Class (15% of the overall grade): During this activity, students will have to answer a questionnaire that will be evaluated and will represent 15% of the mark of the subject.


Seminars (35% of the overall grade): This section evaluates the capacity for analysis and synthesis of the students of each group, as well as the skills of group work and oral presentation.

The seminars will be valued as follows:


Written work

30%


The teacher evaluates (about 10) the work delivered by each group of students (see deliveries)


Oral presentation

50%


The teacher evaluates (about 10) the skills of each group of students in the public presentation of their work


Inter-group qualification


10%


Each group of students evaluates (about 10) the groups that perform the oral presentation


Intra-group qualification


10%


Within each group, each student evaluates (about 10) their peers at the last seminar



TOTAL

100%



Attendance at the seminars is mandatory. If there is no justification left in class, there will be a penalty in the seminar note:

Absence 1 session = reduction of 20% of the note.

Absence 2 sessions = reduction of 40% of the note.

Absence ≥3 sessions = 80% reduction of the note.


Overcoming the subject

To pass the subject, at least 5 points out of 10 must be obtained in the overall computation of written theory and seminar tests.

A student will be considered \"not evaluable\", and therefore will not be evaluated, when it has not been presented to more than 67% of the evaluation activities programmed for the subject.

To participate in the recovery, the student must have been previously evaluated in a set of activities whose weight equals to a minimum of 67% of the grade of the subject

Repeating students

Regarding the passing of the subject by the repeaters, it will not be necessary to repeat the seminars again if the student had previously obtained a minimum grade of 5. This exemption will be maintained for a period of three additional tuition fees


Unique assessment

This subject foresees the single assessment system. In this sense, this consists of a single synthesis test that will be done to coincide with the same date fixed in the calendar for the last continuous assessment test and the same system will be applied in case of need for recovery.


Any irregularity committed during an assessment activity (academic misconduct, plagiarism, or improper use of AI, unless such use is expressly authorized in the course syllabus) that may lead to a significant alteration of the grade will result in that activity being graded as 0. If the course syllabus stipulates that obtaining a minimum mark in this assessment is an essential requirement to pass the course, or if multiple irregularities occur in the assessment activities of the same course, the final grade for the course will be 0. Furthermore, disciplinary proceedings may be initiated against any student who incurs any of these irregularities.
