The purpose of the brain's gyri and sulci, or ridges and grooves, is to increase surface area.
<h3>What is the name for the raised ridges in the cerebrum?</h3>
The shallow grooves on the cerebral cortex's surface are referred to as sulci, while the higher tissue ridges are called gyri.
Signals are transferred between nerve cells in different regions of the brain and body through white nerve fibres that are below the skin. The neocortex, a six-layered structure present in animals, has a wrinkled surface that enhances its surface area.
The cerebellum has an odd surface appearance that hides the fact that the cerebellar cortex, a layer of grey matter, makes up the majority of the structure. This layer's ridges are collectively referred to as folium.

The percent of the body surface area burned to the front torso is 36% and front of the right arm is 4.5%.The total body surface area involved in burn is 40.5% calculated by Rule of Nines.
The total body surface area (TBSA) is an easy way to get a rough burn size estimate that can be used when calculating a patient's fluid resuscitation needs.
The Rule of Nines or Wallace Rule of Nines, is a common tool used by healthcare professionals to assess the total body surface area involved in burn patients.
The Rule of Nines is estimated by assigning percentages to different body areas. For instance, the entire head is estimated as 9%, the entire trunk is estimated at 36% and each arm is estimated at 9%.
The total body surface area (TBSA) of a burn can also be calculated with a Lund and Browder Chart.

Classification follows an order of simpler first, then the more complex one. The classification of organisms into different groups is helpful in determining the relationship between different organisms, as well as tracing the evolutionary history of a specific organism or group of organisms. The divisions in which organisms are sorted are called taxonomic ranks and they are:
Domain, kingdom, phylum, class, order, family genus and species.
