Contents
Physiology studies the vital functions that allow humans to analyze the environment in which they live, move, communicate, reproduce and survive. Physiology investigates the mechanisms underlying the normal functioning of the organism, and also explains its control and regulation, integrating the function from the molecular level to the whole organism. The man is not a sum of organs, nerves or muscles, but a single whole. This functional solidarity is made possible by the integrative activity of the nerve centers and the unifying concept of homeostasis of the internal medium.

Educational objectives
The altered functioning of organs or apparatuses due to exogenous and / or endogenous causes beyond the limits that our organism is able to control and correct constitutes the pathological condition, on which the pharmacological treatment intervenes.
Therefore, Physiology defines the necessary and fundamental premises for the understanding of Pathology and Pharmacology.
The course has set itself the goal of illustrating the general operation of the main equipment, and stimulate the students' research of cellular and molecular mechanisms that underlie higher functions.
Prerequisites
In order to be able to understand and to know how to tackle the course, students must have the basic notions of human anatomy and biology, propedeutics to physiology.
Teaching methods
The course is organized as follows: Lectures on all subjects of the course.
Projection of movies concerning some topics that will complement the lectures.
Other information
Frequency: Compulsory, at least 70% of lessons
Learning verification modality
The exam consists of an oral test. Such oral test consists on an interview of about 30-40 minutes long aiming to ascertain the knowledge level and the understanding capability acquired by the student. The oral exam will also test the student communication skills and his autonomy in the organization and integration of the theoretical topics.
