Seven Main Parts of the CNS

Most caudal part of the nervous system receives and processes sensory information from skin, joints, and muscles controls movement of the limbs and trunk subdivided into cervical, thoracic, lumbar and sacral continues rostrally as the brain stem

Brain stem conveys information to and from the spinal cord and brain brain stem regulates levels of arousal and awareness through reticular formation brain stem consists of medulla, pons, and midbrain

Lies above medulla conveys information about movement from the cerebral hemisphere to the cerebellum

lies directly above the spinal responsible autonomic functions such as digestion, breathing, and heart rate

Lies behind the pons, connected to the brain stem by several major fiber tracts called peduncles modulates the force and range of movement involved in the learning of motor skills

Lies rostral to the pons, controls sensory and motor functions including eye movement and the coordination of visual and auditory reflexes

Contains two structures: hypothalamus and the thalamus

Processes most of the information reaching the cerebral cortex fro the rest of the central nervous system

Regulates autonomic, endocrine, and visceral functions

Consists of the cerebral cortex, basal ganglia, hippocampus, and amygdaloid nucleus

Helps regulate motor performance

Involved with memory storage

Coordinates autonomic and endocrine responses in conjunction with emotional states

Medulla, pons, cerebellum
