Learning outcomes of the course unit
Acquisition of the knowledge on the mechanisms at the basis of cellular and tissue homeostasis, on transport and communication mechanisms and on resting metabolic rate.
Acquisition of the knowledge on the functions of the different organs and apparata, their dynamis integration and the general mechanisms of corntrol of their functions in rest conditions and during physical activity.
To know the main functional parameters in healthy individuals
To know the main mechanisms od the sensory and motor functions of the central nervous system and of sensorimotor transformation processings.
