Ch. 1 Flashcards
Inspection
Identify changes from normal
Percussion
Hollow vs. solid sounds
Ascultation
stethoscope
Palpation
touch
No ill effects, real-time image, not good clarity, uses high frequency soundwaves and echoes
Ultrasound
lighted instrument w/ lens, good image
Endoscopy
quick, simple, 2 dimensional, inexpensive
x-ray
inserts injected into body make hollow organs visible
contrast x-ray
x-ray that is better at soft tissue and organ detail because the x-ray source rotates around the body and completes revolutions; 3 D
computed tomography (CT)
not as detailed for bones, magnet source, not for patients with metal in the body, BEST at soft tissue resolution
MRI
Look at physiology, metabolism, examine activity levels, dark = metabolicly active
Positron Emission Tomography (PET)
metabolic activity of tissues, shows tissue activity
Radionucleotide Scanning
One system at a time, relating back to systems
Systemic approach to study anatomy, what we use
visible with unaided eye
gross
slides of tissues and cells
microscopic
Levels of Organization
Chemical, Cellular, Tissue, Organ, System, Organism
The relative constancy of the internal environment of the body even with external fluctuations
Homeostasis
T or F: size of system correlates with its importance
F
Why is anatomical position so important?
So there is a standard everyone references when discussing location of organs within the body/starting point
Regions of the body?
Head, neck, trunk, upper extremities, lower extremities
Subdivisions of the trunk
Thorax/chest, abdomen, pelvis
Organs in Right Upper Quadrant
liver, gallbladder, right kidney, portions of stomach, small and large intestine
Organs in LUQ
left lobe of liver, stomach, pancreas, left kidney, spleen, portions of small and large intestine
Where do quadrant lines intersect?
Umbilicus
Organs in RLQ
cecum (part of large intestine), appendix, portions of small intestine, reproductive organs (right home in females, right spermatic cord in males), right ureter
