Sleep patterns

Meal patterns

Question 8

What is the timing of biological rythms determined by?

Answer 8

Factors inside and outside the body

Question 9

What are endogenous pacemakers?

Answer 9

Some aspects of our biological rythms are set by genetically determined biological structures inside our body

Question 10

What are exogenous zeitgebers

Answer 10

Influences outside the body which act like a prompt and may trigger a biological rhythm

Question 11

Do endogenous and exogenous factors interact?

Answer 11

Yes they interact to regulate the timing of our biological rythms

Question 12

Answer 12

Animal studies can’t be accurately generalised
Studies that have deprived humans from light have still allowed artificial light which reduces validity
Individual differences
