Intracellular / extracellular
Interstitial fluid, lymph, blood plasma, cerebrospinal fluid, and synovial fluid are what type of fluids?

Nervous system / endocrine system

Feedback system
Three components comprise a feedback system:
A receptor, a control center, and an effector
Responses that reverse the original stimulus involve ___ feedback.
Responses that intensify the original stimulus involve ___ feedback
Negative
Positive
A ___ is an abnormality of structure and/or function
Disorder
A ___ refers to an illness accompanied by a set of clinically observable, measurable changes called signs, and subjective changes experienced by a patient called symptoms.
Disease
Anatomical position
Body is erect, head and feet facing forward, arms at sides with palms forward
Prone position
Lying face down
Supine position
Lying face up
Sagittal plane
Divides body or organ into right and left sections
Called midsagittal (median) when plane runs through midline resulting in equal sides
Frontal (coronal) plane
Divides body or organ into front and back sections
Transverse (horizontal) plane
Results in upper and lower sections
