The term "parietal" generally refers to structures related to the walls of a cavity or organ. In anatomy, it often describes the parietal bones, which are two large bones in the skull that form the sides and roof of the cranium. These bones protect the brain and provide attachment points for muscles. In a broader context, "parietal" can also relate to the parietal lobe of the brain, which is involved in processing sensory information such as touch, temperature, and pain. This lobe plays a crucial role in spatial awareness and coordination, helping individuals navigate their environment effectively.
