Question 1

Define Homeostasis

Answer 1

Homeostasis is the condition of equilibrium in the body’s internal environment (Maintaining the internal environment)

Question 2

Examples of controlled variables of homeostasis

Answer 2

Temperature, Ion concentrations, Blood sugar levels, Fluid balance

Question 3

Define feedback

Answer 3

When the controlled variable moves too far from the set point and responses from the body attempt to move the variable back to “normal”

Question 4

Define feedforward

Answer 4

When there is an anticipation of an event that qill alter a controlled variable, in order to minimise the effect

Answer 19

Flexion, Extension, Dorsiflexion, Plantarflexion, Abduction, Adduction, Circumduction

Question 20

What is flexion movement

Answer 20

Decreasing angle, limbs brought together

Question 21

What is extension movement

Answer 21

Increasing angle, limbs held apart

Question 22

What is dorsiflexion movement

Answer 22

Toes brought up to face (bad feet)

Question 23

What is plantar flexion movement

Answer 23

Toes pointing towards ground (good feet)

Question 24

What is abduction movement

Answer 24

Movement at joint away from midline (away)

Question 25

What is adduction movement

Answer 25

Movement at joint towards midline (towards)

Question 26

What is circumduction movement

Answer 26

Combination of four movements (flexion, abduction, extension, adduction)
