The nervous system is composed of neurons or nerve cells and their supporting structures. Types of Neurons There are three classes of neurons; each class corresponds to a different aspect of nervous system function. Sensory Neurons. Sensory or afferent neurons are specialized to detect stimuli and transmit information about them to the central nervous system. These neurons may connect any organ to the central nervous system. A stimulus is a change in the environment; it may be light, heat, pressure, or a chemical, for example.
Although there have been no general studies of life expectancy in people with cerebral palsy, most children affected by CP live between 30 and 70 years, depending on the severity of the condition.
Cerebral palsy information. Cerebral palsy is a condition resulting from damage to the areas of the brain that control movement. It is not a disease. People with cerebral palsy (CP) can have a range of chronic movement and posture disorders. Once the disorder appears, usually in the first few years of life, it doesn't worsen. Cerebral palsy can range from mild to severe and is purely a physical impairment.
