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.

Answer:
cockroaches and other insects
Answer:
B. The pathogen must be grown in pure culture.
Explanation:
Virus, and also some bacteria can not be cultured in "lifeless media". In the case of bacteria, we refer to the obligate intracellular ones, and all virus. Thus, this postulate can not be fulfilled in all cases. Virus can be propagated on tissue cultures, but certainly this was not considered by Koch. Moreover, these methods often result in spontaneous genetic alterations, which leads to adaptation and even attenuation in animal models of disease, so, the cultured virus perhaps does not induce the same disease when introduced to another specimen.
Answer:
what exactly do you need help with? like whats the question?
1. Axon
2. Electrons
3. A wave of reversal of the negative electrical potential inside the cell passes along the axon with ions moving in and out of the axon.
4. branch of nervous tissue was compressed, so electrical signals could no longer travel through her arm.
5. The brain sends signals to the blood vessels in the legs to dilate, so that there is increased blood flow. (This one seems the most accurate)
