1. ANATOMY LECTURE 1 Anatomy vs. Physiology Anatomical Directions

2. ANATOMY VS. PHYSIOLOGY Anatomy is the study of the structures in the body (ie form)  Greek for “cutting up” Physiology is the study of the functions of particular structures (ie function)  Greek for relationship to nature Dissecting a frog and noticing there are muscle striations: Anatomy or Physiology? Noticing when certain muscles are flexed, an arm moves: Anatomy or Physiology?

3. ANATOMICAL DIRECTION It’s all RELATIVE! Something could be anterior in one instance and posterior in another!

4. SUPERIOR VS. INFERIOR Superior=ABOVE Inferior=BELOW *Think “I am superior (above) you. Your are inferior (below) me”* Is your foot SUPERIOR or INFERIOR to your knee? Is your brain SUPERIOR or INFERIOR to your heart?

5. ANTERIOR VS. POSTERIOR Anterior(ventral)=FRONT Posterior(dorsal)=BACK *With this one, I like to think about a DORSAL fin being on a fishes’ back…Or your posterior is your butt….* Are your eyes ANTERIOR or POSTERIOR to your brain? Are your heels ANTERIOR or POSTERIOR to your toes?

6. MEDIAL VS. LATERAL Medial=MIDDLE Lateral=AWAY FROM MIDDLE *Medial and Middle both start with “M”* Is your belly button more MEDIAL or LATERAL than your eye? Are your toes more MEDIAL or LATERAL than your nose?

7. PROXIMAL VS. DISTAL Proximal=CLOSER TO TRUNK Distal=FURTHER FROM TRUNK *Distal sounds like distant* Is your knee more PROXIMAL or DISTAL than your toes? Are your feet more PROXIMAL or DISTAL than your head?

8. SUPERFICIAL VS. DEEP Superficial=CLOSE TO THE SURFACE Deep=FURTHER AWAY FROM THE SURFACE *I don’t think I need to explain this one…* Is your skin more SUPERFICIAL or DEEP than your heart?
