Physiology of the Skin
A.Y. 2020/2021
Learning objectives
The course aims to provide knowledge regarding the physiology of the skin and to describe in depth the specific functions carried out by this complex organ and the annexes for the well-being of the organism. Alterations in pathological conditions will also be considered.
Expected learning outcomes
At the end of the course students will be able to describe the mechanisms involved in the normal functions carried out by the skin and skin annexes and the alterations characterizing pathological conditions.
Lesson period: Second semester

Course syllabus and organization
Single session
Responsible
Lesson period
Second semester
In relation to a possible continuation of the emergency phase due to the pandemic, the lessons will be held on the Microsoft Teams (MT) platform and it will be possible to attend them both synchronously and asynchronously, since they will be recorded and left available to students on the same Teams platform as well as on the Ariel website of the course. In the possibility to carry out the lessons in presence, students will be informed by communication on the Ariel website.
Course syllabus
Skin morphology
Specific functions of the skin layers (epidermis, dermis and hypodermis) and skin annexes (hair, nails, sweat glands and sebaceous glands).
Protective functions of the skin: mechanical, physical (against radiation, temperature), chemical and biological protection.
Secretory functions and modulation of electrolyte equilibrium. Synthesis of vitamin D.
Sensory functions: physiology of sensory receptors for touch, propriocetion, thermocetion, pain (somatosensory system); adequate stimuli, signal transduction mechanisms, genesis and propagation of bioelectric signals, ascending nerve pathways, cortical representation and processing.
Thermoregulatory functions: vascularization of the skin, autonomic regulation, thermogenesis and thermodispersion mechanisms.
The microbiota of the skin and skin annexes
The permeability of the skin
Physiological changes in the integumentary system during aging. Skin lesions: primary, secondary, melanoma.
