Intro to Structure and Function
Directional Orientation Guiding Questions: 1. What does directional orientation tell you about a patient? 2. Make a chart of the various directional orientation terms 3. Why would a veterinarian and a doctor have a disagreement about the words anterior, ventral, posterior, and dorsal?
Why get so technical? Communicates precise information Used in procedures, therapies
Directional Orientation Explains a particular view of a person/subject
Biped vs. Quadruped
Directional Planes Guiding Questions: 1. How are directional planes different from directional orientation terms? 2. Make a chart of the various directional planes terms
Directional Planes Views of imaginary lines sliced through a person/subject “Midsagittal” Plane
Positions Guiding Questions: 1. What do position terms indicate? 2. Why do you think there are so many different positions?
Some Positional Examples Dorsal recumbent Knee-chest Lithotomy Sim’s Sitting Trendelenberg Mod.
Why so many positions to know? Trendelenberg Allows better access to the pelvic organs as gravity pulls the intestines away from the pelvis Increases blood flow to the brain Sitting Examination of heart, lungs, head, eyes, ears, nose throat
More positions: Fowler’s position Promote drainage or ease breathing Upper body may be reclined Knee-chest position Used for rectal and vaginal examinations and as treatment to bring uterus into normal position
Even more positions! Dorsal recumbent Vaginal examinations Obstetrical forceps Supine – Palpating internal organs, front of body
Almost done! Prone Used to examine spine and back, legs Sim’s used for rectal examination, treatments and enemas Lithotomy Examination of pelvic organs
