1 Ch. 1 : Introduction to Anatomy & Physiology
Bases on 9th ed. Fundamentals of Anatomy and physiology by Martini/Nath/Bartholomew Ch. 1 : Introduction to Anatomy & Physiology

2 Physiology IF, THEN OBSERVATIONS, LOGICAL Connections
Cell physiology – cell functions at the chemical and molecular levels Organ physiology – specific organs ; cardiac function Things like stroke volume and cardiac output Systemic physiology – cardiovascular physiology Blood pressure involves the heart, lungs and kidneys Pathological physiology – effects of disease on the function of organs or systems. Comparing normal functioning with that of disease state

3 Good Study Strategies PARTICIPATE ASK QUESTIONS Read the book
Use the online resources Make flash cards Take ‘good’ notes – ones that make sense to you Use a variety of methods – learn those that work for you Do the HW assignments Handout on study strategies; also on website; based on pg 3, check pt pg 4

4 Separate MEDICAL TERMINOLOGY Hand Out
Anatomy & Physiology History back 1500 years “Structures and Functions” Anatomy is Greek for ‘to cut open’; study structures and their relationships to each other; both internal and external features. Which muscles attach to which bones, with what tendons and at what points… who – what – where – size – shape – location, etc Physiology is also Greek. It refers to how functions are performed. How does a muscle actually contract (in order to move a bone)? This would be how and why. “Specific functions are performed by specific structures.” Separate MEDICAL TERMINOLOGY Hand Out Check pt. pg 5 and Medical Terminology handout

5 Anatomy DETAILS Gross Anatomy (aka Macroscopic)
Gross means “large” or “whole” Surface anatomy – general form Regional anatomy – spatial relationships Systemic anatomy – organs and organ systems * Developmental anatomy - embryology Clinical anatomy – lots of areas used in medical field Microscopic Anatomy Cytology – focus on cells Histology – focus on tissues * Know the 11 organ systems (Integumentary, skeletal, muscular, nervous, endocrine, lymphatic, circulatory, respiratory, digestive, reproductive and urinary)

6 Levels of Organization
Chemical ( molecule) – even at this level form determines function… electrons, bond type and bond angle, 3D shapes of molecules like enzymes Cellular – phosphate and lipids give properties to things like CM and phospholipid bilayer Tissue – collection of cells working to perform one function Organ – two or more tissues working in combination System * know 11 systems with organs and functions Organism * Organ systems handout with pg 8 -9

7 Spotlight figure 1.1 Levels of Organization
Pgs. 8 -9 Systems, organs and functions will be on quiz

8 Homeostasis and Feedback
Homeostasis => existence of a stable internal environment, even when external conditions vary “Homeostatic regulation” is adjusting physiological reactions so the body can respond to both normal and abnormal conditions. Autoregulation: (aka intrinsic) if oxygen levels decrease in a tissue, cells will release chemicals that cause local blood vessels to dilate (expand) - more blood = more O2 Extrinsic regulation: nervous and/or endocrine systems cause changes in other systems. After you eat blood is diverted to digestive system organs to absorb nutrients and away from other systems Feedback loops ( pg. 11)

9 More feedback Negative Feedback is a response used to counteract the current state Ex: runner is too hot ( body tem over 98.6) so you sweat and dilate blood vessels – red skin; lots of blood near surface so heat can cause water to evaporate. Temp gets lower and lower and lower until it is normal. Positive Feedback is a response that keeps increasing the current state. Rarely used in everyday biological reactions Ex: clotting (pg 14) , labor and lactation State of Equilibrium or Dynamic Equilibrium

10 Anatomical Terms - regions
Superficial = near the surface Landmarks used to relate terms; brachium means arm, so brachial artery and brachialis muscle are both found in the arm Position – standard anatomical position is arms at side, palms forward, feet together. Supine, laying face up Prone, laying face down Regions …. Worksheets (there are several plus a lab)

11 Anatomical Terms - sections
Work sheets and pages16 – 21 Vocab lists for Ch. 1 and Ch. 2

12 Turnitin.com Assignment for Anatomy
Choose a disease or clinical condition Check with me that other students haven’t already claimed your topic Read 5-8 articles on the subject You are required to do 5; 7 and 8 are extra credit Write a review of each article in the form of an Annotated Bibliography Alphabetical Summarize C/C to other articles and relate to class topics See sample on website Will be due Monday March 14, 2016

13 Clinical Notes and Reading
Read examples on pgs. 6 and 12 And additional reading – summarize one article about a disease condition related to organs, tissues or feedback. Use Gale through media center to get to academic journals This will be part of turnitin.com assignment in December  Article about a disease/disorder/condition Article about one way to treat (address) the disease 2nd article about an alternative approach Paper that compares and contrasts the treatments; side effects; success rates, costs, etc.
