- Femur
Q3.Which protective membranes surround the brain and spinal cord?
- Tendons
- Ligaments
- Meninges
- Cartilage
Q4.The cerebrospinal fluid (CSF) mainly helps by:

Short questions
Q1. Name the three main structures that protect the human brain.
Q2. What is the role of cerebrospinal fluid (CSF) in protecting the brain and spinal cord?
Q3. What are meninges? Why are they important?
Q4. A student falls while playing cricket but is wearing a helmet. Explain how the helmet helps reduce the risk of brain injury.
Q5. Why is the vertebral column important for the protection of the spinal cord?

Q1. Draw a neat and properly labelled diagram showing the protective coverings of the brain. Explain the functions of the skull, meninges, and cerebrospinal fluid.
Q2. Describe how the spinal cord is protected inside the human body. Explain the role of the vertebral column, meninges, and cerebrospinal fluid.
Q3. Describe how the spinal cord is protected inside the human body. Explain the role of the vertebral column, meninges, and cerebrospinal fluid.
Q1. During a road safety awareness programme, 120 students participated in a survey.
Answer the following:
How many students reported wearing a helmet at least sometimes?
What percentage of students always wear a helmet?
What percentage never wear a helmet?
Suggest one reason why wearing a helmet is important for protecting the brain.
Q2.A school conducted a first-aid awareness test on protection of the nervous system.
Answer the following:
How many students participated in the test?
Calculate the percentage of students who answered correctly.
Calculate the percentage of students who gave incorrect responses.
Mention one step that schools can take to improve awareness about protecting the brain and spinal cord.
Q3.Read the following situation:
A student slips on a wet staircase in school. Fortunately, the student is carrying a properly fitted backpack and receives immediate first aid. The doctor later explains the importance of protecting the brain and spinal cord during accidents.
Based on this situation, answer the following:
Identify the bones that protect the brain.
Name the structure that protects the spinal cord.
State the function of cerebrospinal fluid in such situations.
Explain why immediate medical attention is important after a head or back injury.
Suggest one precaution that could help prevent similar accidents in school.
