88169 - SKIN AND SKIN ANNEXES PHYSIOLOGY

Conoscenze e abilità da conseguire

Dopo aver frequentato questo corso e aver superato l’esame finale, lo studente conosce la fisiologia della pelle e degli annessi cutanei.

Contenuti

Physiology of the integumentary system and the oral cavity: an overview.

Specific functions of the skin layers (epidermis, dermis and hypodermis) and skin annexes (hair, nails, sweat glands and sebaceous glands).

Protective functions: mechanical, physical (against radiations, temperature, electricity), chemical and biological (including immune) protection.

Permeability and prevention of dehydration.

Secretory functions and modulation of electrolyte balance. Vitamin D synthesis.

Specific functions of the structures of the oral cavity (lips, tongue, palate, gums and teeth).

Sensory functions: physiology of sensory receptors for touch, proprioception, thermoception, pain (somatosensory system), smell (olfactory system) and taste (gustatory system); adequate stimuli, mechanisms of signal transduction, genesis and propagation of bioelectrical signals, ascending neural pathways, cortical representation and elaboration.

Autonomic nervous system (regulation of activity; efferent pathways; sympathetic and parasympathetic divisions; neurotransmitters and receptors).

Thermoregulatory functions: vascularization of the skin, autonomic regulation, mechanisms of thermogenesis and thermodispersion.

Physiological changes of integumentary system and oral cavity structures during aging.

Practical exercises: exercises using interactive software; functional tests in humans.

Articles and other materials provided in the classroom.

Metodi didattici

Lectures are conducted in a classroom using Power Point presentations.

Practical exercises are carried out in a computer room; 1) Students are guided in the use of interactive software; 2) Students will learn to perform functional tests in humans.

Modalità di verifica e valutazione dell'apprendimento

Student learning in the Integrated Course “Skin and skin annexes Anatomy and Physiology and Diseases” will be assessed in three oral tests, each of them evaluated in thirtieths; students must have passed the first test to take the second one, and the second test to take the third one. 1) The first test concerns the teaching module "Skin and skin annexes Anatomy"; 2) the second test (which can be taken on the same day of the first test or later, within twelve months) concerns the teaching module "Skin and skin annexes Physiology"; 3) the third test (which can be taken on the same day of the first and the second test or later, within twelve months) concerns the teaching module "Skin and skin annexes Diseases". Each test is passed if the mark is equal to or higher than 18/30; the final mark is the arithmetic average of the marks reported in the three tests.
