Anatomy & Structure Flashcards
anatomy
study about (body) structure through dissection
physiology
study of the functions of living organisms and their parts
structure fits function
each part has particular size shape form position in the body in direct relation to it’s ability to perform a unique specialized function
scientific method
observation, hypothesis, experimentation, theory or law
levels of organization
(chemical, organelle) cellular, tissue, organ, organism
gross structures
large structures
anatomical position
erect or standing posture arms at the side palms forward
bilateral symmetry
left and right sides mirror each other
median
middle
not anatomical position
supine - laying down facing upward
prone - laying face down
superior direction
toward the head, upper, above
inferior direction
toward the feet, lower, below
anterior
front or in front of
posterior
back or in back of
ventral
toward the belly (aka front)
dorsal
toward the back (aka back)
medial
toward the midline or middle of the body
lateral
toward the side of the body or away from the midline
proximal
toward the nearest trunk of the body or nearest point of origin
distal
away from, farthest from trunk of body, farthest from point of origin
superficial
nearer the surface
deep
farther away from the surface
sagittal plane
cut or section length wise from front to back, divides the body into left and right halves
parasagittal plane
plane length wise that divides the body into UNEQUAL right and left halves
midsagittal plane
plane length wise that divides the body into EQUAL right and left halves
frontal plane
length wise plane that divides the body into anterior (front ventral) and posterior (back dorsal)
transverse plane
length wise plane that divides the body or any of its parts into upper (superior) and lower (inferior) portions
movement planes
planes can also be used to describe movement
main major body cavities
ventral (anterior) and dorsal (posterior)
cranial cavity housed in the
dorsal cavity
spinal cavity housed in the
dorsal cavity
thoracic cavity housed in the
ventral cavity
pleural cavity housed in the
ventral cavity
mediastinum housed in the
ventral cavity
diaphragm housed in the
ventral cavity
abdominal cavity housed in the
ventral cavity
