Regulating basic biological needs is a function of the a. cerebrum b. hypothalamus c. thalamus d. forebrain

Regulating basic biological needs is a function of the Hypothalamus. Hypothalamus is a part of the brain that has a vital role in controlling many bodily functions including the release of hormones from the pituitary gland. Cerebrum is the most superior and anterior part of the brain. It consists of two cerebral hemispheres separated by the flax cerebri of the dura mater, It is involved in reason, planning, memory, and sensory integration. Thalamus is a small structure within the brain located above the brain stem between the cerebral cortex and the midbrain and has extensive nerve connections to both. It relays motor and sensory signals to the cerebral cortex.
