Name the two structures in the CNS
Brain and Spinal Cord
How many lobes are found in the cerebrum?
Four
Which lobe is located at the front of the brain?
Frontal
Name the three types of neurons.
Motor, sensory and interneuron.
Name the 5 structures within a neuron.
Dendrite, Cell body, Axon, Myelin Sheath and Axon Terminal
What is the main function of the CNS?
To process information and control responses.
Which part of the brain is the largest?
Cerebrum
Which lobe is mainly responsible for emotional regulation and decision making?
Frontal Lobe
Occipital
Which lobe helps you recognise faces and understand language?
Temporal
Damage to which lobe would most likely affect personality?
Frontal
Which lobe is responsible for touch, pain and temperature?
Parietal
The cerebellum is mainly responsible for:
balance and coordination
Damage to which part of the brain is likely to be fatal?
Brain Stem
Identify the three main parts the brain is divided into.
Cerebrum, Cerebellum and Brainstem
Define the term stimulus.
A stimulus is a change in the environment that causes a response in the body.
Identify the stimulus and receptor involved when you step into bright sunlight.
Stimulus: Bright Light
Receptor: Eyes
Define reflex.
A reflex is an involuntary response that protects the body from harm.
Why are reflex actions faster than normal responses?
What is the effector in the knee-jerk reflex?
The muscles in the leg.
State the structure that is not involves in the reflex response but is involved in other responses in the nervous system.
The brain
Identify the correct sequence of the stimulus response model
Stimulus --> Receptor --> Control centre --> Effector --> Response
Explain the difference between a stimulus and a response.
A stimulus triggers a reaction.
A response is the action taken as a result.
Describe the stimulus response pathway involved in pulling your hand away from a hot object.
Stimulus: Hot object
Receptors: Skin
Control Centre: Spinal Cord
Effector: Muscles in arm
Response: Move hand away
Describe the stimulus-response pathway involved when you smell rotting fish.
Stimuli: Smell of fish
Receptors: Nose
Control Centre: Brain
Effectors: muscles in arms or legs
Response: Move away from bin or cover nose.
