    Study Notes

    Introduction to Physiology

    • Dr. Arzu Temizyürek is the faculty member teaching this course in the Department of Physiology at the Faculty of Medicine.
    • The recommended textbooks for the course are "Textbook of Medical Physiology" by Guyton & Hall, "Review of Medical Physiology" by W.F. Ganong, and "Neuroscience" by Dale Purve.

    Physiology

    • Physiology is an integrative science that deals with the basic functions of living organisms, derived from the Greek words "physis" meaning nature and "logos" meaning science.
    • It is the branch of science that studies the functions of living organisms.

    Physiological Terms

    • Function refers to what an organ or system does, while mechanism or process refers to how it does it.

    Normal and Abnormal Conditions

    • Physiological refers to normal functions of tissues, organs, or the body, whereas pathophysiological refers to abnormal conditions or functional changes associated with disease or injury.

    Levels of Structural Organization

    • There are six levels of structural organization in the human body: chemical, cellular, tissue, organ, organ system, and organism.

    Organization of Life

    • The cell is the basic unit of life, and there is a hierarchical organization of cells, tissues, organs, organ systems, and organism.

    Focus of Physiology

    • Physiology focuses on the level of organs and systems within systems, which are groups of related organs with a common function.

    Homeostasis

    • Homeostasis is the process of maintaining the stability of the human body's internal environment in response to changes in external conditions.
    • It requires a sensor to detect changes, an effector mechanism to vary the condition, and a negative feedback connection between the two.

    Central Nervous System

    • The central nervous system has sensory and motor divisions, which work together to maintain homeostasis.
    • The sensory division detects changes, the control center processes information, and the effector mechanism responds to the stimulus.

    Homeostatic Regulatory Systems

    • There are two types of homeostatic regulatory systems: intrinsic (local) regulation, which involves auto-regulation within cells, tissues, or organs, and extrinsic regulation, which involves the nervous or endocrine systems.

    Communication Within the Body

    • Long-distance communication within the body is accomplished through the nervous system, which uses neural electrical impulses, and the endocrine system, which uses hormones.

    Homeostatic Regulation Mechanism

    • Feedback loops are used to maintain homeostasis, and they have three components: a receptor/sensor, a control/integration center, and an effector.

    Negative Feedback

    • Negative feedback loops stabilize the variable being regulated and aid in maintaining homeostasis.
    • The control mechanism decreases the intensity of the condition to bring it back to the set point.

    Positive Feedback

    • Positive feedback loops are not homeostatic and are found in a few reflex pathways.
    • The output becomes the stimulus input for the process itself.
