What are some of the practice questions on the central nervous system?

Practice Questions on the Central Nervous System (CNS)


The Central Nervous System (CNS) consists of the brain and spinal cord, playing a crucial role in processing information and controlling bodily functions. Here are some practice questions categorized by difficulty level:  


🧠 Basic Level Questions:

1. What are the two main components of the central nervous system?  

2. How does the CNS differ from the              peripheral nervous system (PNS)?  

3. What is the primary function of the spinal       cord?  

4. Name the three main parts of the brain.  

5. What role does the **cerebrospinal fluid (CSF)** play in protecting the CNS?  

⚡ Intermediate Level Questions:  

6. Explain the function of the **medulla oblongata** in controlling involuntary actions.  

7. How do neurons in the CNS communicate with each other?  

8. What is the difference between **white matter** and **gray matter** in the brain?  

9. What is the function of the **hypothalamus** in regulating body temperature and hunger?  

10. How does the **blood-brain barrier (BBB)** protect the CNS?  


Advanced Level Questions:

11. Describe the process of **synaptic transmission** between two neurons in the CNS.  

12. What happens in the CNS during a **reflex action**, and why does it occur so quickly?  

13. Explain the impact of **neurotransmitters** like dopamine and serotonin on brain function.  

14. How does damage to the **cerebellum** affect movement and coordination?  

15. Discuss the role of the **limbic system** in emotions and memory.  


Clinical & Research-Based Questions: 

16. What are the common symptoms of **CNS disorders** like Parkinson’s and Alzheimer’s disease?  

17. How does **multiple sclerosis (MS)** affect the CNS, and what are its possible causes?  

18. What role does the CNS play in **pain perception**?  

19. What is the effect of **anesthesia** on the central nervous system?  

20. How does brain plasticity help in recovery after a CNS injury, such as a stroke?  


📌 Why These Questions Matter?

These questions help students, medical aspirants, and researchers understand the CNS in-depth. Answering them improves critical thinking and application of neuroscience concepts in real-life scenarios.

**What Are the Best Ways to Lose Weight? (Simple, Effective, and Proven Methods)**

Struggling with stubborn fat that just won’t go away no matter how hard you try? You’re not alone.

Age zyada hona koi galti nahi hai.

Age zyada hona koi galti nahi hai.Zindagi ek race nahi hai jisme sabko ek hi speed aur ek hi time pe sab kuch achieve karna ho.

Akela Rehna Galat Nahi: Akele rehna bhi ek choice hai, aur woh bhi strong aur independent hone ki nishani hai. Tum khud ke saath khush rehna seekh lo, baaki duniya secondary ho jaati hai. Jo log khud ke saath comfortable hote hain, woh sabse zyada powerful hote hain.   3. Relationship ki Value: Woh ladka tumse chhota tha, ab uski shaadi ho rahi hai—that’s okay. Har relationship ek lesson deta hai, aur woh tumhe strong banata hai. Tumhare liye jo sahi hai, woh apne time pe zarur milega.   4. Li...

Why did the radar forensic data for the Alaska plane crash reveal a rapid loss in elevation and a rapid loss in speed?

The radar forensic data for the Alaska plane crash likely revealed a *rapid loss in elevation and speed* due to several possible factors:    ✈️ Mechanical Failure  – Engine malfunction, structural damage, or control system issues could have led to a sudden descent.   🌪Severe Weather – Ice buildup, turbulence, or strong winds might have impacted the aircraft’s stability.   🧭Pilot Error or Spatial Disorientation – Loss of control in bad visibility can cause rapid altitude loss.   🔥Catastrophic Event – A mid-air explosion, bird strike, or external impact could explain the sudden drop.   Investigators will analyze,black box data, pilot communication, and weather conditions* to determine the exact cause.What do you think could have played a major role in this incident?
