Question

question 19 1 pts the ridges on the cerebral cortex that are surrounded by sulci are called _______.
○ divisions
○ lobes
○ gyri
○ fixtures

Explanation:

To solve this, we recall the anatomical terms related to the cerebral cortex. Sulci are the grooves, and the ridges surrounded by sulci are called gyri. "Divisions" is too general, "lobes" are larger regions of the brain, and "fixtures" is not an anatomical term for this structure.

Answer:

C. gyri
