exam 1 Flashcards
(25 cards)
the scientific discipline that investigates the bodys structure, such as the size and shape of a bone
anatomy
the scientific investigation of the processes or functions of living things
Physiology
structures examined without a microscope
gross
studied area by area
regional
studied system by system
systemic
external form used to visualize deeper structures
surface
structures so small they require aid of a microscope
cytology, histology
what structure can be examined without a microscope
regional, systemic, surface
cellular anatomy
cytology
study of tissue
histology
electromagnetic radiation moves through the body and is exposed on photographic plate; creates radiograph
x-ray
sound waves pass into the body and bounce back to receiver; visualized as a sonogram
ultrasound
radio waves directed to patient while under electromagnetic field; radio waves collected and analyzed by computer
magnetic resonance imaging (MRI)
computer-analyzed x-ray images
computed tomography (CT)
similar to a CT scan but uses a radiopaque dye to enhance differences in areas
digital subtraction angiography (DSA)
radioactively labeled glucose usage by a tissue is detected; provides info on metabolic state
positron emission tomography (PET)
how the body responds to stimuli and how it maintains stable internal conditions in a constantly changing environment
physiology
examines processes in cells
cell physiology
functions of organ systems
systemic physiology
focuses on the nervous system
neurophysiology
the heart and blood vessels
cardiovascular physiology
interaction of atoms and molecules
chemical level
structural and functional unit of living organisms. combinations of molecules for structures called organelles that carry out specific functions
cell level
atoms, protein, DNA, sucrose
chemical level
