nutrients
oxygen
carbs
fat
proteins
water
maintenance of a stable internal environment in a dynamic system
homeostasis
the output enhances or exaggerates the original stimulus
In positive feedback systems
Regulation of blood clotting
positive feedback systems
variable changes opposite to that of the initial change
negative feedback system
variable change in the same direction to that as the initial change
positive feedback system
some type of sensor that monitors the environment & responds to changes by sending info to the second component
receptor
input flows from the recptor to the control center along the so-called
afferent pathway
level of range at which a variable is to be maintained
set point
what determines the set point
control center
provides the means for the control centers response to the stimulus
effector
Hand withdraws from a painful stimulus such as a broken glass
withdrawal reflex
toward the head
superior (central)
inferior (caudal)
below the head
anterior (ventral)
front of body
posterior (dorsal)
rear of body
medial
towards midline
lateral
away from midline
between medial and lateral
intermediate
toward origin of body part
proximal
distal
away from origin of body
toward body surface
superficial (external)
away from body surfaces
deep (internal)
decrease of joint angle in sagittal plane
flexion
increase of joint angle in sagittal plane
extension
combination of movements that describe an arc or cone
circumduction or circumflexion
decrease in ankle joint angle in the sagittal plane
dorsal flexion (dorsi flexion)
increase in angle joint angle in the sagittal plane
plantar flextion
lateral movement away from the middle of the trunk in the frontal plane
abduction
adduction
medial movement toward the midline of the trunk in the frontal plane
lateral flexion
decrease in joint angle in the frontal plane
rotary movement in the transverse plane toward the midline
internal rotation
rotary movement in the transverse plane toward the midline
external rotation
internal rotation of the radius in the transverse plane
pronation
