What is Cortex?
The cortex, also referred to as the cerebral cortex, is the region of the mammalian brain closest to the outside of the cerebrum. The anatomical term "cortex" refers to the body's outer layer. In reality, the frontal portion of the cortex, which is where higher cognitive functions are located, is where the majority of our intellect actually resides. Additionally, it is the final area of the brain to grow both developmentally and evolutionarily. The heart is the only organ in the human body without a "cortex," since others like the kidneys and ovaries also have an outer layer.
In anatomy, the outside portion or layer of a certain internal organ or tissue is often referred to as the cortex. The cerebral cortex serves as one example. The outermost layer of a vertebrate's cerebrum is called the cerebral cortex. The renal cortex is another another. The kidney's periphery is known as the renal cortex. The cortex in botany refers to the stem and root tissue that extends outward toward the vascular tissues. In some plants, it could be situated halfway between the vascular tissues and the epidermis. The cortex is found in woody plants sandwiched between the periderm and vascular tissue, particularly phloem. Therefore, the cortex is a part of the bark of the tree.
