Explanation Explanation/justification for the correct answer : Option (a) is pia mater. Gyri and sulci are present on the surface of cerebral hemisphere and pia mater is the layer of meninges close to the cerebral hemisphere. Hence, this option is correct. Explanation for incorrect answer : Option (b) is arachnoid mater. Arachnoid mater is the middle layer of meninges and is not in direct contact with gyri and sulci...

Chapter 32, Problem 2PL

Summary Introduction

Introduction:

The cerebral surface in the brain is covered with folded tissues termed as gyri. The grooves or spaces between the gyri are termed as sulci. If sulci are much deeper, then they are termed as fissures. The fissures generally divide the cerebrum into the four lobes.
