Document Summary

Cerebrospinal fluid produced in the ventricles of the brain. Forebrain: brain stem (medulla and pons, cerebellum, reticular activating system, limbic system, cerebrum. Where the spinal cord enters the brain it enlarges to form the stalk-like structure of the brain stem. Medulla: respiration and heart rate, nerve relay between spinal cord and brain, contralateral control. Cerebellum: nerve relay between higher and lower levels of the nervous system, motor control centre , attached to brainstem, muscular motor coordination for fast, reflexive involuntary movements, learning and memory. Reticular system: awareness of incoming stimuli, state of wakefulness (alertness) or sleep for sustained periods of time. The area of the brain that most differentiates humans from other animals. Thalamus: sensory switchboard , relays sensory information to higher brain centres, thalamic abnormalities schizophrenia and disordered sensory information. Basal ganglia: movement, parkinson"s disease affects basal ganglia circuits. Hypothalamus: regulate body functions, autonomic nervous system, hormones, drives. Connected by the corpus collosum: cerebral cortex.
