What does pathology mean? - ANSWER- -study of disease
what is the six levels of structural organization - ANSWER- -chemical, cellular, tissue, organ,

A myocyte is what level of structural organization? - ANSWER- -cellular
Why would a myocyte be cellular? - ANSWER- -Because cyte= cell

What is extrinsic regulation? - ANSWER- -a large problem in the body

What is the receptor? - ANSWER- -an organ or cell able to respond to light, heat, or other
external stimulus and transmit a signal to the control center.
What does the control center do? - ANSWER- -determines set point, analyzes information,
determines appropriate response
What is the effector? - ANSWER- -Fixes the problem of the body to bring it back to
