Chapter 1: Overview of CNS - Major Sulci & Gyri

What is a sulcus?

• a fissure or shallow groove that separates a lobe

• a group of nerve fibers

• a ridge/raised portion of the brain surface

• a type of nerve cell

What is located below the Middle Frontal Gyrus?

What is a gyrus?

• a developing nerve cell

• a fissure or shallow groove that separates a lobe

• a type of glial cell

• a ridge/raised portion of the brain surface
