This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
This unit explores the structure and function of the nervous system, including the CNS, reflex arcs, and the eye. It covers brain structure, common eye defects, and the challenges in treating nervous system damage. It also addresses ethical considerations.
Lesson Summary
You will learn to describe some of the difficulties in studying and treating damage in the nervous system and brain.
Key Notes
- The importance and difficulties of investigating brain function and damage, including safety and ethical considerations.
- Use of fMRI and electrical stimulation to study the brain.
- Difficulties in treating disease and damage in the nervous system and brain (e.g. lack of mitosis in neurones).
- Potential treatments for disease and damage in the nervous system and brain (e.g. stem cells).
Vocabulary To Learn
- ethical: relates to whether an action and its consequences are right or wrong
- informed consent: consent obtained from a patient where they fully understand the procedure and its implications
- mitosis: a type of cell division that produces genetically identical cells
- stem cell: a cell that can differentiate into specialised cells
Common Mistakes To Avoid
- Understanding the ethics of research practices is complex and often misunderstood. The details of various brain scanning techniques are complex and also confusing.
3 Quick Questions (With Answers)
1. Explain the scientific idea in this lesson using two key points.
The importance and difficulties of investigating brain function and damage, including safety and ethical considerations. Use of fMRI and electrical stimulation to study the brain.
2. Define this scientific word and use it in context. 'ethical'
relates to whether an action and its consequences are right or wrong. Include the word in a full scientific explanation, not as a single label.
3. Correct this common scientific misunderstanding.
Mistake: Understanding the ethics of research practices is complex and often misunderstood. The details of various brain scanning techniques are complex and also confusing. Correction: Ethical practices are discussed with examples and changes through history to give context. Brain scanning techniques are illustrated and explained, with follow up tasks.
