The term "Cortex" often refers to the outer layer of an organ, particularly in the brain. In the context of the brain, the cerebral cortex is responsible for many important functions, including thinking, memory, and decision-making. It plays a crucial role in processing sensory information and controlling voluntary movements, making it essential for everyday activities. In addition to its role in the brain, "Cortex" can also refer to the outer layer of other organs, such as the kidney or adrenal glands. Each cortex serves specific functions related to the organ it surrounds, highlighting the importance of this protective and functional layer in various biological systems.
