35-36oC
37-38.5oC
37.5-38.2oC
Which of the following is NOT true of a catabolic reaction?
It is a type of metabolic reaction within the body
An example is the breakdown of glucose to release energy
It requires energy to build complex molecules
The products of the reaction can alter the optimal conditions for other enzyme reactions
In the stimulus-response system, what is the role of the receptor?
It indicates a physical or chemical change in the body which can be detected
It detects the stimuli and sends a chemical message to a coordinating centre
It acts as a stimulus to stop or maintain the behaviour once the conditions are returned to optimal
A muscle or gland which responds if a change is required
Receptors that monitor a factor of the internal environment are called:
Disturbance detectors
Thermoreceptors
Nocireceptors
Misalignment detectors
Which of the following is NOT true of chemoreceptors?
They detect chemical changes in the external or internal environment
Distance chemoreceptors are found on the tongue
Direct chemoreceptors are in direct contact with the origin of the stimulus
There are internal and external chemoreceptors
Which of the following is NOT an example of negative feedback?
Reducing carbon dioxide levels in the bloodstream after exercising
Increasing glucose uptake in the body when levels are too high
Platelets being recruited to form a blood clot
Increasing body temperature through vasoconstriction when exposed to a cooler environment
In a stimulus-response system that is responding to a decrease in temperature, an effector could be:
The decrease in external temperature
Thermoreceptors in the skin
The central nervous system
Muscle movement resulting in shivering

What type of neuron receives a stimuli and carries information to the CNS?
Association neurons
Sensory (afferent) neurons
Motor (efferent) neurons
Interneurons
