- Tissue fluid
Short questions
Q1. State any two functions of the cerebrum.
Q2. Why is the cerebellum important for everyday activities?
Q3. What are meninges? State their role in protecting the brain.
Q4. A student learns to ride a bicycle after practising for several days. Explain which part of the brain helps in maintaining balance and coordination during cycling.
Q5. State two involuntary activities controlled by the medulla oblongata.
Q6. Why is the brain considered the control centre of the human body?
Q1. Draw a neat and properly labelled diagram of the human brain. Describe the location and functions of the cerebrum, cerebellum, and medulla oblongata.
Q2. Explain how different parts of the brain work together when a student reads a question, thinks about the answer, writes it in the answer sheet, and maintains proper posture while sitting.
Q3. During a football match, a player sees the ball approaching, decides to pass it to a teammate, runs forward, and maintains body balance while kicking. Explain the role of different parts of the brain in coordinating these activities.During a football match, a player sees the ball approaching, decides to pass it to a teammate, runs forward, and maintains body balance while kicking. Explain the role of different parts of the brain in coordinating these activities.
Q1. A biology teacher conducted a reaction-time activity with four students.
Answer the following:
Calculate the total reaction time of all four students.
Calculate the average reaction time.
Identify the student with the fastest response.
Find the difference between the fastest and slowest reaction times.
Q2.A class of 50 students participated in a brain-function quiz.
Answer the following:
How many students identified a brain part correctly?
What percentage of students gave correct responses?
What percentage of students answered incorrectly?
Suggest one reason why students may confuse the functions of different brain parts.
Q3.Read the following situation:
During the annual school function, a student walks onto the stage, remembers the speech, speaks confidently, maintains body balance, and continues breathing normally throughout the performance.
Based on your understanding of the human brain:
Identify the part of the brain mainly responsible for memory and thinking.
Identify the part that helps maintain body balance.
Identify the part that controls breathing during the speech.
Explain how these parts work together to perform the activity smoothly.
State why coordination among different parts of the brain is essential in this situation.
