Question

what is sulcus and what is gyrus​

Answer 1

In biological morphology and anatomy, a sulcus is a furrow or fissure. It may be a groove in the surface of a limb or an organ, notably in the surface of the brain, but also in the lungs, certain muscles, as well as in bones, and elsewhere

A gyrus (plural: gyri) is a ridge on the surface of the brain. Each ridge is surrounded by fissures known as sulci (singular: sulcus). Gyri are unique structures that have an important evolutionary function; they increase the surface area of the brain up to an impressive 2000 centimeters squared.
