Nervous system 6 diagram
Specification Link
This nervous system diagram is used for: Identify the medulla as the brain region associated with unconscious activities such as breathing and heart rate.
What To Explain
Information is passed through the nervous system so the body can coordinate a response.
Exam Answer Move
The mapped objective is: Identify the medulla as the brain region associated with unconscious activities such as breathing and heart rate. The answer should connect structures such as receptors, neurones, synapses or effectors to coordination and response.
Brainstem (2) diagram
Specification Link
This nervous system diagram is used for: Describe the brain as an organ made of billions of interconnected neurones that controls complex behaviour.
What To Explain
Information is passed through the nervous system so the body can coordinate a response.
Exam Answer Move
The mapped objective is: Describe the brain as an organ made of billions of interconnected neurones that controls complex behaviour. The answer should connect structures such as receptors, neurones, synapses or effectors to coordination and response.
Breathing Inspiration Expiry diagram
Specification Link
This respiratory system diagram is used for: Identify the medulla as the brain region associated with unconscious activities such as breathing and heart rate.
What To Explain
The medulla coordinates unconscious breathing movements, so breathing rate can change without conscious control.
Exam Answer Move
This is aligned to: Identify the medulla as the brain region associated with unconscious activities such as breathing and heart rate. The answer connects breathing movements with control by the medulla.
Spinal cord sections (1) C5 T2 T8 L1 L2 S2 diagram
Specification Link
This nervous system diagram is used for: Explain that the brain and spinal cord form the central nervous system.
What To Explain
Information is passed through the nervous system so the body can coordinate a response.
Exam Answer Move
The mapped objective is: Explain that the brain and spinal cord form the central nervous system. The answer should connect structures such as receptors, neurones, synapses or effectors to coordination and response.
