describes a position above, toward the head.
superior
describes a position below or lower than another part of the body.
inferior
describes the front or direction toward the front of the body. The toes are _______ to the foot.
anterior (ventral)
describes the back or direction toward the back of the body.
posterior (dorsal)
describes a position at or toward the trunk.
proximal
describes a position away from the trunk.
distal
describes the middle or direction towards the middle of the body.
medial
describes the side or direction toward the side of the body.
lateral
describes a position closer to or at or near the body surface
superficial
describes a position father away from body surface
deep
the plane that separates right and left side
sagittal plane
the plane that separates front from back
frontal (coronal) plane
the plane that separates the lower and upper sections
transverse (horizontal) plane
the physiological value around which a normal range fluctuates
set point
the restricted set of values that is optimally healthful and stable
normal range
a mechanism that reverses a deviation from the set point
negative feedback
a component of a feedback system that monitors a physiological value; also called a receptor
sensor
the component in a feedback system that compares the value to the normal range
control center
the component in a feedback system that causes a change to reverse the situation and return the value to the normal range
effector
the position of the body standing upright with the feet at shoulder width and parallel, toed forward
anatomical position
face down orientation of the body
prone
face up orientation of the body
supine
a two-dimensional surface of a three-dimensional structure that has been cut
section
an imaginary two-dimensional surface that passes through the body
plane
