Spinal cord Topography

The video tutorial covers the topography of the spinal cord, explaining why it terminates at the L1L2 vertebral level and what fills the space below the konus medullaris. It describes the anatomy of the vertebral canal, the developmental discrepancy between the spinal cord and vertebral column, and provides measurements of the spinal cord's length, weight, and width.

What is the name of the structure that fills the space below the konus medullaris?

• Cerebral cortex

• Cauda equina

• Cerebellum

• Medulla oblongata

Why does the spinal cord end at the L1L2 vertebral level in adults?

• The spinal cord develops faster than the vertebral column.

• The spinal cord and vertebral column develop at the same rate.

• The spinal cord develops at a slower rate than the vertebral column.

• The vertebral column stops growing after birth.

What is the approximate length of the adult spinal cord?

• 50 to 55 centimeters

• 20 to 25 centimeters

• 30 to 35 centimeters

• 40 to 45 centimeters

How much does the spinal cord weigh approximately?

• 25 grams

• 45 grams

• 15 grams

• 35 grams

What is the width of the spinal cord?

• Less than 4 centimeters

• Less than 1 centimeter

• Less than 2 centimeters

• Less than 3 centimeters
