3Body Planes:Definition = imaginary lines drawn through the body to separate the body into sectionsRefer to as any slice or cut through a 3 dimensional structureWhat diagnostic exams use this technique?
4Sagittal PlaneDivides the body or organ vertically into right and left unequal parts– words used with this plane include:Medial = body parts located near the middle or midline of the bodyLateral = body parts located away from the midline or middle of the bodyProximal = body parts close to the point of referenceDistal = body parts away from the point of reference
5Midsagittal Plane:Divides the body vertically into EQUAL right and left sides1. Medial = body parts located near the middle or midline of the body2. Lateral = body parts located away from the midline or middle of the body
6Frontal or Coronal Plane: Divides the body into front and back section.1. Anterior = body parts on the front of the body2. Posterior = body parts on the back of the body
7Transverse Plane:Horizontal plane dividing the body into a top and bottom half1. Superior = body parts above other parts2. Inferior = body parts below other parts
8Body Directions Superior – upper or above Inferior- lower or below Anterior or ventral- in front ofPosterior- after or behindmedial- toward the midline- middleLateral – toward the side – away from midlineProximal-toward the truck – near point of attachment
9Body Directions Distal-away from origin or point of attachment Dorsal- near the upper surface- toward the neckVentral- towrd the bottom- toward the bellyCranial-refers to the headCaudal – means tailInternal- inside the body
10Body Cavities: Spaces within the body which contain vital organs Protect organs from shocks and bumpsPermit expansion and contraction without disrupting other organs
11Posterior or Dorsal Cavity: One long continuous cavity that is located on the back of the body, divided into two sectionsSurrounds the brain and spinalcord1. Cranial Cavity = contains the brain2. Spinal Cavity = contains the spinal cord
12Anterior or Ventral Cavity: Larger and separated into two distinct cavities --the chest and abdomen-by a dome-shaped muscle called the diaphragm, which is important for breathing1. Thoracic Cavity = located in the chest, contains the heart, lungs, and the large blood vessels2. Abdominopelvic
132. Abdominal Cavity = divided into upper and lower parts Upper part contains the stomach, small intestines, most of the large intestines, liver, gallbladder, pancreas and spleen3. Pelvic Cavity = lower abdominal cavity containing urinary bladder, the reproductive organs, and last part of the large intestines
14Abdominal Regions: Quadrants 1. Right Upper Quadrant (RUQ)2. Left Upper Quadrant (LUQ)3. Right Lower Quadrant (RLQ)4. Left Lower Quadrant (LLQ)
16Abdominal Regions: Epigastric- above the stomach Umbilical belly button or umbilicusHypogastric or pelvicbelow the stomachHypochondriacbelow the ribsLumbarNear the large bones of the spinal cordIliac or InguinalNear the groin
18Sooooooo…….What if….You have a patient that has gangrene in the lower portion of their leg and you need to amputate….. You would make a ________________ cut through the leg.The abdominal muscles and muscles of the back are separated by the _______________ plane.
19OK, sooooo……. Which cavity is the heart found in? Which cavity contains the spinal cord?Which cavity contains the ovaries?Which cavity contains the lungs?Which cavity consists of the abdominopelvic and thoracic cavities?Which cavity contains the cranial and spinal/vertrebral cavities?
