Introduction

• Overview of brain's internal structures
• Focus on central sulcus and related gyri

Central Sulcus

• Definition: A groove in the brain
• Location: Runs vertically along the brain
• Purpose: Separates the frontal lobe from the parietal lobe

Surrounding Gyri

Precentral Gyrus

• Location: In front of the central sulcus
• Definition: A large lumpy structure
• Contains: Primary motor cortex

Postcentral Gyrus

• Location: Behind the central sulcus
• Definition: Another large lumpy structure
• Contains: Primary somatosensory cortex

Important Terms

• Sulcus: A groove or fold separating different parts of the brain
