Program

1 Biophysics and cellular physiology
Homeostasis and the constancy of the internal environment. Structure of the membrane. Movement of molecules across the membrane. Resting membrane potential, graded potentials, action potential.
2 Muscle
Skeletal muscle: Molecular bases of contraction; neuromuscular junction, excitation-contraction coupling; types of synaptic transmission block; mechanics and energy expenditure of contraction; types of muscle fibres; motor unit; modulation of strength of contraction; muscle fatigue; effects of exercise. Smooth muscle: classification; molecular bases of contraction; excitation-contraction coupling.
3 Nervous System
Functional anatomy of the neuron. Structure of the synapse. Function of excitatory and inhibitory synapses. Temporal and spatial summation. Modulation of synaptic function: short-term and long-term synaptic plasticity. Principles of functional organization of the nervous tissue. Sensory systems: sensory receptors and transduction of sensory stimulus into nerve impulses; classification of sensory modalities; somatic sensation; pain sensation; chemical senses: smell and taste. Motor systems: spinal control of movement; spinal reflexes; alpha-gamma activation; different levels of control of posture and locomotion; functional organization of motor pathways.
4 Cardio-vascular system
Blood tissue: components and regulation of red cells production. The heart: functional structure; rhythmical excitation; excitation-contraction coupling; electrocardiogram in physiology and pathology; the cardiac cycle; regulation of cardiac output and venous return; Starling’s law . Circulation: overview; hemodynamic, pressure, flow, resistance, velocity; arterial pressure, definition, measurement, control; arterioles; local (organ) control of blood flow; capillary flow, diffusion of molecules, filtration and reabsorption of fluids; veins.
5 Respiratory system
Functional anatomy. Ventilation mechanics; Volumes and capacitances of the lungs; partial pressures of the gases; alveolar gas exchanges; respiratory exchange ratio; alveolar ventilation/perfusion ratio; transport of gases in the blood; respiratory center; chemical control of respiration; respiratory alkalosis/acidosis; hypoxia.
6 Kidney
Functional structure. Glomerular filtration, renal blood flow ant their control. Clearance. Renal tubular reabsorption and secretion. Henle’s loop. Control of water and sodium secretion. Control of potassium and calcium secretion. Control of pH.
7 Gastrointestinal system
