Neurons, Brain and Stimulus response

1

100

Name the two structures in the CNS

Brain and Spinal Cord

200

What is the main function of the CNS?

To process information and control responses.

300

Damage to which lobe would most likely affect personality?

Frontal

400

Define the term stimulus.

A stimulus is a change in the environment that causes a response in the body.

500

State the structure that is not involves in the reflex response but is involved in other responses in the nervous system.

The brain

2

100

How many lobes are found in the cerebrum?

Four

200

Which part of the brain is the largest?

Cerebrum

300

Which lobe is responsible for touch, pain and temperature?

Parietal

400

Identify the stimulus and receptor involved when you step into bright sunlight.

Stimulus: Bright Light

Receptor: Eyes

500

Identify the correct sequence of the stimulus response model

Stimulus --> Receptor --> Control centre --> Effector --> Response

3

100

Which lobe is located at the front of the brain?

Frontal

200

Which lobe is mainly responsible for emotional regulation and decision making?

Frontal Lobe

300

The cerebellum is mainly responsible for:

balance and coordination

400

Define reflex.

A reflex is an involuntary response that protects the body from harm.

500

Explain the difference between a stimulus and a response.

A stimulus triggers a reaction.

A response is the action taken as a result.

4

100

Name the three types of neurons.

Motor, sensory and interneuron.

200

Which lobe processes vision?

Occipital

300

Damage to which part of the brain is likely to be fatal?

Brain Stem

400

Why are reflex actions faster than normal responses?

Sensory information is processed in the spinal cord rather than the brain.

500

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

5

100

Name the 5 structures within a neuron.

Dendrite, Cell body, Axon, Myelin Sheath and Axon Terminal 

200

Which lobe helps you recognise faces and understand language?

Temporal

300

Identify the three main parts the brain is divided into.

Cerebrum, Cerebellum and Brainstem

400

What is the effector in the knee-jerk reflex?

The muscles in the leg.

500

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.
