- thin epithelium
simple squamous
gross anatomy Answer - what we see with the unaided eye,
superficial and deep structures
microscopic anatomy Answer - requires magnification
cytology Answer - study of cells
histology Answer - study of tissue
physiology Answer - function
,the structure of capillary walls, Answer - promotes nutrient
and waste exchange
inferior-superior Answer - below- above
rostral- caudal Answer - front- back
anterior - posterior Answer - front- back
ventral- dorsal Answer - front-back
medial -lateral Answer - towards middle- away from middle
proximal- distal Answer - nearer the trunk or attached
end/farther from the trunk or point of attachment

surface
coronal Answer - divides into front and back
transverse Answer - divides into upper and lower
,midsaggital Answer - divides into left and right
homeostasis Answer - the tendency of an organism to
maintain a stable internal environment even though the
external environment changes
homeostatic control systems Answer - monitor the internal
environment and correct as needed
cellular level Answer - local control
organ and organism Answer - reflex control, long distance
signaling
3 major components of a control system Answer - input
(input signal)->controller (integrating center)-> output
(output signal)
the integrators Answer - control centers
integrators Answer - possess a set point
, set points Answer - can be modified. a fever regulates back
to set point, acclimatization regulates environmental
temperature
full response loop Answer - stimulus-> sensor ->input ->
integrating center -> output ->target -> response
heart rate homeostasis is an example of Answer -
antagonistic homeostasis control
sympathetic nerves Answer - increase heart rate
parasympathetic nerves Answer - decrease heart rate
glucose homeostasis Answer - 2 primary hormones
insulin Answer - lowers blood glucose levels
`glucagon Answer - raises blood glucose levels
feedback Answer - process in which some part of the output
of a system is returned to its input in order to regulate its
further output
