Cerebrum
Interprets sensory impulses arriving from sense organs and centers for initiating voluntary muscular movements. Stores information that comprises memories and helps reason. Intelligence and personality.
Medulla Oblongata
All ascending and descending nerve fibers connecting to the brain and spinal cord must pass through this area. Control vital visceral activities. Relay ascending impluses to the other side of the brainstem and then to higher brain centers
Pons
Relay impulses to and from the medulla oblongata and cerebrum. Ventral portion has large bundles of transverse nerve fibers, which transmit impulses from the cerebellum to centers within the cerebellum. Relay sensory impulses from peripheral nerves to higher brain centers. Maintain basic rythm of breathing
Cerebellum
Communicates with other parts of the CNS by means of three pairs of nerve tracts called Cerebellar puduncles. Brings sensory information concerning position of limbs, joints, and other body parts to the cerebellum. Sends correcting impulses to the midbrain. Reflex center for intergrating sensory information concering position of body parts and for coordinating complex skeletal muscle movements. Maintains posture.
Thalamus
Central relay station for sensory impulses ascending from other parts of the nervous system to the cerebral cortex. Receives all sensory impulses (except smell) and channels them to appropriate regions of cortex for interpretation. Produces a general awareness of certain sensations, such as pain, touch, and temperature.
Hypothalamus
Maintains homeostasis to the cerebral cortex, thalamus, and other parts of the brainstem. Regulates visceral activities by linking the nervous system and endocrine systems. Heart rate, blood pressure, body temperature, water/electrolyte balance, control hunger/body weight, movements nad glandular secretions of stomach and intestines,
