Human Body Organization Flashcards
exam 1
Anatomy
scientific discipline investigating body structure and form
Microscopic anatomy types
cistology: examines structural features of cells
histology: examines components of tissues
macroscopic/ gross anatomy
investigates structures visible to the naked eye
systemic macroscopic anatomy
study of each functional body system (ex: study of the respiratory system as a whole)
regional macroscopic anatomy
study of all structures in a region as a unit (ex: axilla)
surface macroscopic anatomy
study of superficial anatomical markings and related internal structures
anatomical position
standard position of reference for description of anatomical structures: erect, upper limbs at side, hands palm forward (anterior), legs shoulder width, toes forward
supine
lying on back
prone
lying face down
anterior vs posterior
anterior: in front
posterior: behind
ventral vs dorsal
ventral: toward belly
dorsal: toward back
medial vs lateral
medial: toward midline
lateral: away from midline
superficial vs deep
superficial: toward surface
deep: away from surface
superior vs inferior
superior: above
inferior: below
cephalic vs caudal
cephalic: toward head
caudal: toward tail
proximal vs distal
proximal: near attachment at trunk
distal: far from attachment at trunk

loin
acromial
point of shoulder
sural
calf
olecranon
point of elbow
dorsum
back of hand
popliteal
hollow area behind knee
sagittal plane
vertically, divides left to right
median plane
sagittal plane creating equal left and right sides
transverse/cross plane
horizontally, superior/inferior sections
frontal/coronal plane
vertically, anterior/posterior sides
transverse/cross section
cuts at the right angle to the length of an organ
longitudinal section
cuts along the length of an organ
what are the dorsal cavities
cranial cavity, spinal canal
what are the ventral cavities
thoracic + abdominopelvic
oblique section
cuts at any angle but right
spinal canal
the dorsal cavity housing the spinal cord, formed by bone to protect it
thoracic cavity
the ventral cavity containing 2 plural cavities, one for each lung.
what divides the thoracic cavity?
the mediastinum (heart, thymus)
diaphragm
separates the thoracic cavity from abdominopelvic cavity, allows us to breathe
serous membranes
double layered, slippery membranes that enclose the cavity, serous fluid is found in between to lubricate
visual for serous membrane
fist (organ) pushing through a balloon (the serous membrane)
visceral vs parietal serous membrane
visceral: inner wall
parietal: outer wall
pericardium
the serous membrane of the heart
pleura
the serous membrane of the lungs
peritonium
the serous membrane of the abdominopelvic cavity
