MCQ Detailed View

The spinal cord is a vital part of the central nervous system (CNS) that runs through the vertebral column and connects the brain to the peripheral nervous system. It is organized into distinct regions, each responsible for controlling specific parts of the body and relaying sensory and motor signals.

The main regions of the spinal cord include:

• 
  

  Cervical region: Located at the neck, controlling signals to the arms and upper body.

  
  


• 
  

  Thoracic region: Located in the upper and mid-back, associated with the chest and trunk muscles.

  
  


• 
  

  Lumbar region: Found in the lower back, controlling signals to the legs.

  
  


• 
  

  Sacral region: Located below the lumbar region, responsible for lower limb and pelvic organ functions.

  
  

Among the given options, Pelvic is not a recognized anatomical region of the spinal cord. While the pelvic area is served by nerves originating from the sacral region, “pelvic” itself is not classified as a separate spinal cord region. Therefore, the correct answer is Pelvic.

The spinal cord’s regional organization allows for efficient transmission of nerve signals, supporting movement, reflexes, and organ function. Each region contains segments that give rise to spinal nerves, which exit the spinal column and innervate specific body parts. Understanding the regions of the spinal cord is fundamental in human anatomy, neuroscience, and medical studies, helping explain how injuries in specific regions can affect body function.

In summary, the spinal cord consists of cervical, thoracic, lumbar, and sacral regions, while pelvic is not considered a distinct region. This knowledge is essential for understanding nerve pathways, body coordination, and spinal anatomy.
