Nervous System
The human body is made of three nervous systems. They include: The central nervous system, the peripheral nervous system, and the autonomic nervous system.
The central nervous system is composed of the brain and spinal cord. The periphel nervous system connects the Central Nervous System with all the tissues of the body. The autonomic nervous system, "involuntary" nervous system, controls activities of the body unconsciously. It contains all the nervous outside the spinal chord and brain stem.
Disorders
- Dementia (a progressive and sometimes irreversible loss of intellectual function that eventually impairs an individual's ability to work and socialize)
- Stroke (a neurological disorder attributable to sudden interruption of the blood supply to part of the brain)
- Parkinson's Disease (is a movement disorder characterized by progressive tremor at rest, stiff limbs and trunk , slow movements , quiet voice , loss of facial expression, loss of postural control, and other symptoms)
- Huntington's Dosease (a hereditary, progressive degeneration of the central nervous system)
- Epilepsy (the tendency to excessive electrical excitability of the brain)
- Attention Deficit Hyperactivity Disorder (have problems focusing their attention and learning new concepts)
- Tay-Sach Disease (a progressive genetic enzyme deficiency in infants and young children that results in neurological deterioration and leads to an early death)
