Prerequisites

There are no prerequisites for taking this course. However, in order to ensure the proper achievement of the learning aims, it is recommended that students have passed the subject of Animal and Cell Biology in the first semester of the first year of the Degree. Also, the consistency in daily work and the ability to observe is important.


Objectives and Contextualisation

Morphology I is a basic subject in the first year of the Degree that helps to make the student know the structure and organization of domestic animals to understand the function of the organs, tracts and systems that composes the animal organism, during the individual development and during the adult stage. In particular, Morphology I focuses on the study of general embryology, the basic tissues that composes the body and the Locomotor apparatus. The subjects Structure and function of the nervous system, Morphology II and Physiology complement the contents related to the structure and the function of the organ systems of the animal body.

The formative objectives of the subject are:

- To understand the origin and organization of the structures of animals during their development, the basic concepts of the mechanisms that control their development, as well as the etiology and meaning of development anomalies.

- To understand the microscopic structure of cells and tissues as the basis for studying the organs that compose the domestic animals.

- To understand the shape, structure, disposition and function of the organs that make up the Locomotor apparatus in the different species of veterinary interest.

- To the embryological, histological and anatomical terminology correctly and appropriately.

- To know how to use the embryological, anatomical and histological knowledge as a basis for the study of other preclinical and clinical subjects.

- To access and to use critically information sources on embryology, anatomy and histology in an autonomous and adequate manner.

Methodology

The methodology used during the teaching and learning process is based on the student efficiency analyzing the information that our team made available through different means. The main role of the teacher is to help the student, not only giving information, but also directing and supervising the learning process. The course is based on the following activities:

Master classes: The student acquires the scientific knowledge of the discipline. The student must complete this knowledge with the personal and autonomous study of the topics explained.

Practical sessions: Practical sessions approach the theoretical models to reality and reinforce, complete and allow to apply the knowledge acquired in master classes. At the beginning of the course, the student will receive a practical guide describing the contents studied in each session. In practical sessions, the students grouped in small groups will study dissections, bones, preparations of isolated organs, models, x-rays, histological preparations, etc. Throughout the observation of these specimens, the student will acquire a three-dimensional concept of the structural disposition, required to understand, for example, the movement of joints, the muscular biomechanics, the distribution of vessels and nerves, or the juxtaposition of adjacent structures. In practical sessions, the student will also develop manual dexterity and skills, such as curiosity and observation. The attendance to the practical sessions will be controlled.

The student's learning will be monitored through different evaluative tests in continuous assessment, including dissection and microscopy. These tests will evaluate the understanding of practical sessions and the integration of theoretical contents acquired in master classes.

The materials used in the subject will be available on the Moodle platform.

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

This subject does not provide for a single evaluation program. The evaluation will be performed continuous along the course, for the better monitoring of the teaching and learning processes, encourage the continuous effort during the semester and verify the compliance of competences assigned.

Evaluation of practical sessions: There will be 5 controls or tests of continuous evaluation during the course; 3 tests corresponding to the histology block and 2 tests corresponding to the locomotor block. Qualifications obtained will worth 5% of the final grade (also for students repeating the course). In addition, for the better integration of practical contents of different blocks, one evaluation will be performed at the end of each block. The evaluation of the practical contents of Block 1 (Embryology) will be completely included in the corresponding written exam, with an overall assessment 25% of the final qualification for the subject. Practical contents of Block 2 (Basic Tissues) will be assessed through a microscope examination, and will worth 12% of the final grade of the course. Practical contents of Block 3 (Locomotor apparatus) will be assessed through an oral examination performed in the dissection room, using the specimens dissected during the anatomy practical sessions. The oral practical examination of Block 3 (Locomotor apparatus) will worth 30% of the final grade of the course. A minimum grade of 4.5 points out of 10 will be required in the practical examinations of Blocks 2 and 3 in order to average with other qualifications and, consequently, to pass the course.

Written evaluations: Two partial examinations will be conducted: the first one corresponding to the Block 1 (General Embryology) and the second one including contents of Block 2 (Basic Tissues) and Block 3 (Locomotive apparatus). These examinations will evaluate both theoretical and practical concepts corresponding to each Block. Overall, written exams will worth 53% of the final grade.Aminimum grade of 4.5 out of 10 will be required in each written examination to average with other qualifications and to pass the course. Theoretical examinations allow to evaluate the integration of theoretical knowledge with those acquired in practical sessions, the ability to relate and analyze concepts, and overall knowledge and skills of the student.

The following table shows the weight of each examination on the final grade:

The student's final grade will be calculated from the average of all his partial grades. The course will be approved with a final grade of 5 or higher

Students with a minor grade than 4.5 out of 10 in the practical exam of Basic tissues or oral exam of the Locomotive apparatus or any one of the three partial written examinations will have the opportunity to recover them at the end of the semester. The continuous assessment of practices won’t be recoverable.

The student who has not been made any partial exam, including theoretical or practical ones, will be considered as "No Avaluable". The student who made one partial exam but not further exams will be considered Failed. If the student failed the course, the grades corresponding to overcome blocks (Embryology, Basic Tissues and Locomotives) can be saved.
