Question

ventral ramus
white matter
gray matter
denticulate ligament

Explanation:

Identify highlighted structure

Using the Spinal Cord Anatomy and Spinal Cord Gray Matter knowledge points

• The cross-section shows a vertebra enclosing the spinal cord.
• Inside the spinal cord, the butterfly-shaped central region is highlighted in red.
• This central butterfly-shaped region of the spinal cord is composed of neuronal cell bodies, dendrites, and unmyelinated axons, which is anatomically defined as the gray matter.
• The surrounding lighter region is the white matter, and the lateral extensions anchoring the cord are the denticulate ligaments. Therefore, the highlighted red region represents the gray matter.
