Lecture 2 Flashcards
Define Homeostasis
Homeostasis is the condition of equilibrium in the body’s internal environment (Maintaining the internal environment)
Examples of controlled variables of homeostasis
Temperature, Ion concentrations, Blood sugar levels, Fluid balance
Define feedback
When the controlled variable moves too far from the set point and responses from the body attempt to move the variable back to “normal”
Define feedforward
When there is an anticipation of an event that qill alter a controlled variable, in order to minimise the effect

Name the 3 divisions of the body
Coronal, Sagittal, Transverse
Coronal Plane - division and movement
Front and back sections - side to side movement
Sagittal Plane - division and movement
Left and right sections - front and back movement
Transverse plane - division and movement
Top and bottom sections - rotating movement
Name the types of angular movement (7)
Flexion, Extension, Dorsiflexion, Plantarflexion, Abduction, Adduction, Circumduction
What is flexion movement
Decreasing angle, limbs brought together
What is extension movement
Increasing angle, limbs held apart
What is dorsiflexion movement
Toes brought up to face (bad feet)
What is plantar flexion movement
Toes pointing towards ground (good feet)
What is abduction movement
Movement at joint away from midline (away)
What is adduction movement
Movement at joint towards midline (towards)
What is circumduction movement
Combination of four movements (flexion, abduction, extension, adduction)
