Final answer:
The adjective form of 'cerebrum' is 'cerebral', describing anything related to the cerebrum, the part of the brain responsible for higher mental functions like memory and reasoning.
Step-by-step explanation:
The adjective form of cerebrum is cerebral. The cerebrum is the largest part of the brain and is responsible for higher neurological functions such as memory, emotion, touch, sight, and hearing. It consists of the cerebral cortex, which is the outer gray matter covering the forebrain, characterized by wrinkles and folds known as gyri and sulci.
The cerebral cortex is a crucial component for conscious intellectual functions like reasoning, language, and memory. Within the cerebrum are two distinct halves known as the cerebral hemispheres, which are separated by the longitudinal fissure and connected by the corpus callosum allowing for communication between both areas. The cerebrum is involved in various aspects of advanced mental functions, making the adjective cerebral relevant when describing things pertaining to the intellect or the brain.
