Why is the bodies core temperature 37oC?
Optimum temperature for enzymes
No specific reason
To limit the enzymes rate of reaction
Its not 37oC

Motor Neurones - Relay Neurones - Motor Neurones
Sensory Neurones - Relay Neurones - Multiple Neurones
Sensory Neurones - Motor Neurones
What joins neurones together?
Synpases
The are physically attached
Radio signals
CNS
Which of the following ISN'T a thermoregulatory strategy for warming up?
vasoconstriction
shivering
sweating
extra layers of blubber (fat)
In which of the following, do blood vessels near the surface of the body loosen up to release heat?
Vasoconstriction
Vasodilation
The graph above shows changes in body temperature of an endotherm with time.
Which one of the following accurately describes the regulatory mechanism shown in the graph?
A - Negative feedback
B - Positive feedback
C - Thermoregulation
Both A and C
Which best describes the stimulus-response model?
Stimulus -> receptor -> effector -> control center -> response
Stimulus -> receptor -> control centre -> effector -> response
Stimulus -> effector -> control center -> receptor -> response
temperature regulation center in the brain of a human
hypothalamus
thermoregulation
receptor
negative feedback
How do the muscles affect regulation of body temperature?
Errector pili muscles make hair stand up
Shivering increases heat
Muscles do not help regulate body temperature
Shivering decreases heat
