Define homeostasis as dynamic equilibrium, then explain thermoreceptor and hypothalamus control of effectors and interpret heat-loss or temperature data during exercise.
The brain is responsible for processing information and coordinating responses.
Some seizures can result in an increase in body temperature.
Suggest how a seizure in part of the brain could lead to an increase in body temperature.
An answer that includes the following points:
- \{impulses / electrical activity\} from the neurones at site of seizure (1)
- \{arrive at / travel to\} the thermoregulatory centre in the hypothalamus (1)
- description of consequence that would lead to increased body temperature (1)
ACCEPT impulses travel to sweat glands
e.g. reduce sweating / increase metabolic rate increased respiration
