Neurone
Specialised cells of the nervous system that conduct electrical impulses through the body.
What way does the electrical impulse travel on the neuron?
Towards the cell body by a sensory fibre and away from it by an axon fibre
What does the cerebrum do?
Controls memory, personality and reasoning.
What does the cerebellum do?
Controls coordination and balance.
What does the medulla do?
Controls heart and breathing rate.
What is the animal storage carbohydrate found in the liver?
Glycogen
What hormone controls the process of turning glucose into glycogen?
Insulin
What hormone controls the process of turning glycogen into glucose?
Glucagon
What detects a stimulus?
A receptor
What are the main features of a reflex action?
Involuntary and prevents damage to the body
How does is an electrical impulse sent between two neurons?
Chemical diffuses across the synapse
Where is glycogen stored?
Liver
What is the path of an electrical impulse in the reflex arc?
Receptor (Stimulus detected)
Sensory neurone
Inter neurone (CNS)
Motor neurone
Effector (response made)
