Document Summary

Neurology: study of anatomy, functions, and organic disorders of nerves and the nervous system. Functions of the nervous system: sensory function - to sense changes (known as stimuli) both outside and within the body, integrative function - processing the information received from the sense organs. The impulses from these organs are analysed and stored as memory. The many different impulses from different sources are sorted, synchronised and co-ordinated and the appropriate response initiated: motor function - the response to the stimuli that causes muscles to contract or glands to secrete. Three main parts of the brain: brain stem. Spinal cord: of dogs is divided into regions that correspond to the vertebral bodies (the bones that make up the spine) in the following order from neck to tail: cervical, thoracic, lumbar, sacral, and caudal segments. Meninges: specialized tissue that covers the brain and spinal cord. Cerebrospinal fluid: surrounds and protects the brain ventricles and spinal cord.
