anatomy chapter 1

structure

what the "naked eye" can see

deals with structures too small to be seen with the naked eye

the functions (chemistry & physics)

chemical, cellular, tissue, organ, organ system, organism

subatomic particles, particles, atoms, molecules, compounds

little organs - structures found inside cells

histology

systemic approach (vs. regional)

population, community, ecosystem, biome biosphere

organization, metabolism, responsiveness, movement, development, growth, reproduction

includes both anabolism AND catabolism

building up

breaking down

ability of an organism to adjust

joints of body, organs, cells

maturation, differentiation

to become something else

maintaining a relatively constant internal environment

considered positive or negative feed back

mechanism responds by reducing/turning off/negating the effect (thermostat)

mechanism responds by increasing/turning up the effect (childbirth)

essential for describing relative location - supine, baseline

palms facing forward/upward (as if holding a bowl of "soup/supe")

so that we can make comparisons

front

back

below

above

middle

side

Closer to the point of attachment

away from the point of attachment

near the surface

away from the surface

same side

opposite side

anatomical planes

divides body into left and right

divides body into front and back sections

divides the body into top and bottom sections

dorsal and ventral

cranial and vertebral

thoracic and abdominopelvic

parietal

visceral

secrete watery fluid

pleura, pericardium, peritoneum

lungs

heart

"guts"

help provide clear communication of where organs/wounds are located

X-rays, CT (CAT), MRI, PET, Ultrasonography

radiation - penetrates solids, can damage cells

multiple X-ray sections/planes

magnetic resonance imaging (magnets create radio signals)

positron emission tomography (functional)

sound waves ("echos")
