OVERVIEW

General Physiology investigates the functions of living organisms by analyzing the fundamental and unifying mechanisms of life processes in chemical and physical terms.

The discussion is articulated from the molecular and cellular level, to subsequently consider the interactions between cells and the functioning of the most important organs and systems, up to the analysis of integrated functions that involve different systems. The teaching takes into consideration the general physiology of mammals and in particular of the human being, with hints at its evolutionary origin.

AIMS AND CONTENT

LEARNING OUTCOMES

Promote the understanding, acquisition of knowledge, analytical skills, application skills, and communication skills related to:

1. General principles and common mechanisms that regulate cellular functions (intercellular communication; propagation of nerve impulses, synaptic transmission, sensory receptors, muscle contraction)
2. Fundamental aspects, cellular and molecular mechanisms of the functions of the main organs and systems, and the main integrated functions that involve various systems, with reference to the vegetative life and the relational life of the human being (sensory, motor and autonomous nervous system; cardiovascular system; respiratory system; excretory system and osmoregulation; digestive system; energy balance; endocrine system and reproduction).

AIMS AND LEARNING OUTCOMES

The course aims to guide students to the understanding, the acquisition of knowledge, analytical skills, application skills, and communication skills relative to the fundamental principles and mechanisms of the functioning of mammalian organisms (and in particular of humans), their systems, their organs, with particular reference to the cellular and molecular level. The course also aims at acquiring technical-scientific linguistic and communicative skills specifically related to the discipline.

Through attending lectures, participating in classroom activities, individual study on manuals notes and educational material, the exercise of applying acquired knowledge to specific problems, and the exercise of communicating acquired knowledge, the course aims to achieve the following objectives:

• being able to describe the common mechanisms that regulate, in chemical-physical terms, cellular functions, the general principles that govern the functions of the organism and their cellular and molecular mechanisms;
• being able to apply the knowledge learned to the analysis of concrete examples of specific physiological phenomena, to the formulation of a hypothesis for their explanation, or to the formulation of hypotheses of expected results for experiments concerning the physiological processes dealt with during the course, thanks to the use of critical thinking and the ability to argue the hypotheses formulated
• acquire an overview, knowing how to identify relationships, analogies and differences between the physiological systems treated and between the cellular and molecular mechanisms treated in different physiological contexts, which allow to identify and explain conceptual connections between different topics of the program
• being able to understand and use in the exposition in an appropriate way the technical-scientific language specific to the discipline for the purpose of clear and effective communication at the academic and professional level.

PREREQUISITES

In order to aim at the achievement of the course objectives, it is necessary to have previously acquired:

• Elements of Mathematics (algebra, exponentials and logarithms), General Chemistry.
• Knowledge of Cellular Biology, Histology and Anatomy suitable for dealing with topics related to the functioning of the cell and its molecular components.
• Knowledge and mastery of the Italian language (understanding and production, written and oral) and the specific terminology of the disciplines that are part of the knowledge included in the prerequisites
• Understanding of written and oral English (B2 level).

It is then recommended as an optimal prerequisite to have started to acquire:

• Elements of Physics (classical mechanics, thermodynamics, electronics), Physical Chemistry and rudiments of Organic Chemistry and Biochemistry suitable for dealing with biological themes.

TEACHING METHODS

The course includes lectures that encompass the description of the principles and operating mechanisms provided by the program, in-depth studies, examples, explanations, and connections, with the constant aid of images (educational illustrations, data graphs, diagrams, scientific images), and frequent use of videos, to guide students to a systematic and thorough understanding of the program topics, and to the identification of key concepts on which to build their own conceptual network of the subject, as well as to provide an example for the acquisition of linguistic, expository, analytical, applicative, and argumentative skills that the teaching aims at.

The lectures will be periodically interspersed with:

• instant-polls as a method of self-assessment, formative evaluation of the achievement of the specific objectives of the individual parts of the teaching, also useful to direct integration actions to achieve these objectives and to promote deep learning;
• analysis of examples, cases, and specific problems to be briefly addressed in pairs, groups, and collectively (according to teaching methods such as “think-pair-share”) to stimulate interest, reflection, understanding, analytical skills, applicative skills, critical thinking, communicative and argumentative skills, and promote deep learning.

Achieving the teaching objectives will require individual study on one of the reference manuals. Students can then take advantage of the slides shown in class and a series of questions for self-assessment of the knowledge acquired, expository and linguistic skills, and a series of examples and problems for the exercise and self-assessment of the acquired skills of analysis, critical thinking, synthesis, argumentative skills, and making connections between different topics of the program.

Any Student with documented Specific Learning Disorders (SLD), or with any special needs, shall reach out to the Lecturer(s) and to the dedicated SLD Representative in the Department ( Prof. Luca Raiteri, Luca.Raiteri@unige.it ) before class begins, in order to liaise and arrange the specific learning methods and ensure proper achievement of the learning aims and outcomes. VERY IMPORTANT: any request for compensatory tools and adaptations in the exam MUST be done within 10 working days before the date of the exam according to the instructions that can be found at https://unige.it/disabilita-dsa/comunicazioni

EXAMS

EXAM DESCRIPTION

Oral exam. The access to the oral test may be regulated by passing a written test or a basic qualifying question.

ASSESSMENT METHODS

The oral test will aim at assessing the understanding and knowledge of the topics in the syllabus, the ability and appropriateness of exposition in an organic, systematic and synthetic way with a technical language suitable for the disciplinary context, the ability to make connections, and apply knowledge to the analysis of specific cases or ideal experiments to formulate well-argued hypotheses. The final evaluation will positively consider participation during the lessons. A sufficient evaluation will be considered for students who demonstrate sufficient knowledge and understanding of all the main contents of the program with a sufficient level of depth and a sufficient expository capacity. Consequently, the lack of preparation of entire sections of the program (corresponding to at least one hour of lesson) will correspond to an insufficient evaluation, as it will also not be sufficient to demonstrate remembering a good amount of details if this is not associated with a sufficient understanding, knowledge and overall vision or if this does not concern all sections of the program.
