Thursday, August 18, 2016 Physiology Introduction - Physiology is the study of body function - Anatomy is the study of body structure - 6 Levels of Anatomy and Physiology: • Molecular - protein structure • Cellular - certain characteristics and functions • Tissues- groups of cells acting in a similar manner - Epithelial - linings and coverings - Connective - connect and support - Nerve - coordinate body functions - Muscle - provide movement • Functional Units - repeated groups of several kinds of tissues • Organs - consist of many tissues and may or may not be made of functional units • Organ Systems - several organs interacting - Key Concept: Homeostasis is the action of the body to maintain a steady internal environment. The conditions it controls fall within optimal ranges, meaning they are not a constant state, but they body is constantly monitoring them to ensure they stay in that healthy range - Set Point - idealized ‘value’ of a condition that the body tries to maintain. These ‘magic number’ values differ from person to person, but in the medical field we use averages across a population to assess health of individuals - Homeostatic Mechanisms/Feedback Systems: • Negative Feedback System - series of events in which the presence of the end product reduces the rate of production of itself by affecting an earlier step in the process 1 Thursday, August 18, 2016 • Positive Feedback System - series of events in which the presence of the end product increases the rate of production of itself by affecting an earlier step in the process • Feed Forward Response - this occurs when the body responds in anticipation of an environmental change, like your mouth watering before you actually eat any food. Though the pathway hasn't been stimulated, the body is essentially preparing for what it thinks is coming and activating the pathway on its own - Systems work as a Reflex, which is a pre-programmed chain of events • Stimuli act on Receptors, which by the Afferent Pathway send a signal to the Integrating Center, which organizes the information and sends the appropriate instructions via the Efferent Pathway to the Effector who creates the response - Types of Reflexes: • Neural - electrical signal • Endocrine - hormone signal • Neuro-Endocrine - combination • Local - without the integrating center 2
