Slide 1

Objectives: Lesson 1 TSWBAT define anatomy and physiology and sub-divisions. TSWBAT evaluate how anatomy and physiology are closely related. Slide 2 What do you know?? Write down definitions for the following: anatomy from the Greek for a cutting up physiology from the Greek for relationship to nature Slide 3 Overview of Anatomy Anatomy is. the study of the structure and shape of the body Includes both internal and external structures of the body Slide 4 Andreas Vesalius- Father of Human Anatomy A Belgian physician, Andreas Vesalius, was the first to dissect human bodies to study anatomy. He wrote a book on human anatomy in 1538. This book was the first accurate description of the interior of the human body. 1514-1564 Slide 5 2 Main Divisions of Anatomy I. Gross Anatomy II. Microscopic Anatomy Concerned with those structures in the body large enough to be seen with the naked eye. A microscope or magnifying instrument is used to see very small structures in the body. Slide 6 Forms of Gross Anatomy Surface the study of general form and superficial markings Regional focuses on the anatomical organization of specific areas of the body (head, neck, trunk) Systematic study of the structure of organ systems (skeletal system) Developmental describes the changes in form that occur between conception and physical maturity Clinical subspecialties in clinical practice (surgical anatomy) Slide 7 Subdivisions of the Study of Anatomy: Microscopic Anatomy Cytology study of the cell (simplest units of life) Histology study of tissues Slide 8 Physiology Physiology - the study of the functions of the body, often at the cellular or molecular level. Physio = nature Ology = the study of Slide 9 Sub-groups of Physiology Considers the operation of specific organ systems Cardiovascular physiology is the study of? Neurophysiology is the study of? Renal physiology is the study of? Respiratory physiology is the study of? Pathophysiology is the study of? Exercise physiology is the study of? Slide 10 Relationship between Anatomy and Physiology Anatomy and Physiology are always related All specific functions are performed by specific structures. Structure therefore, determines function Example: A loss of a particular cell type brings on diabetes. Diabetes effects the system (Anatomy) and the function (Physiology). Slide 11 Real world application doctor visit Physicians normally use a combination of anatomical, physiological, chemical, and psychological information when they evaluate a patient When a patient presents symptoms; the physician will look at the structures affected (Gross anatomy) Collect a fluid or tissue sample (Microscopic anatomy) Evaluates your physiological processes by asking questions Slide 12 Anatomy and Physiology Relationship An anatomist and a physiologist are asked to examine a car and report their findings. What would an anatomist do? What would a physiologist do? Slide 13 Ticket out Describe how anatomy and physiology are closely related? How are they different?
