PPT-Localising the lesion – where in the nervous system?

CRAIG HICKSON amp Helga Magnusson Aims and objectives Definitions of the CNS amp PNS To learn the signs associated with LMN and UMN Brief recap on the functions associated with different lobes. A. Bacterial Infections of the Nervous System. 1. Bacterial Meningitis. A) Although bacteria can infect the brain, spinal cord, and peripheral nerves, they more commonly infect the meninges and cerebrospinal fluids resulting in meningitis. Functions of the Nervous System. Sensory input – gathering information. To monitor changes occurring inside and outside the body. Changes = stimuli. Integration. To process and interpret sensory input and decide if action is needed. Central. Nervous. System. (CNS). Peripheral. Nervous. System. (PNS). 2. ". You have brains in your head..

The nervous system has 2 major components:. Central Nervous System (CNS). Peripheral Nervous System (PNS).. The CNS. The Central Nervous System includes the brain and the spinal cord. . They are so important to the human body that they are encased in bone for protection.. The nervous system works by sending electrical impulses along neurones (nerve cells).. The Nervous System. There are two main parts:. Central nervous system. – brain and spinal cord. A network of nerves. Cognitive Neuroscience. David Eagleman. Jonathan . Downar. Chapter Outline.
