Question

The Intervertebral disc is related to all of the following except

• A. To the aorta anteriorly
• B. to the 2nd lumbar nerve closely
• C. The cauda equina of spinal cord
• D. is the site of origin of Psoas major

Answer 1

The correct option is A To the aorta anteriorly

• An intervertebral disc lies between adjacent vertebrae in the vertebral column. Each disc forms a fibro cartilaginous joint to allow slight movement of vertebrae and act as ligament to hold the vertebrae together.
• There are five intervertebral disc in the lumbar region (L1-L5). Cauda equina is a bundle of spinal nerves and spinal nerve rootlets consisting of second to fifth lumbar nerve pairs.
• Psoas major is a lengthy fusiform (spindle shaped) muscle that can be found on the side of the lumbar region of the vertebral column. It originates from vertebral bodies, intervertebral disc, transverse processes of T12-L5.
• Aorta is the main artery of the human body originating from the left ventricle of the heart.Hence aorta is not related to intervertebral disc.
  
• So,the correct answer is 'To the aorta anteriorly'.
