Study Notes
Diseases of the Nervous System
- Bell's Palsy is an affliction of the Facial Nerve, causing difficulty in tasting food.
- Poliomyelitis is a disease that damages somatic motor neurons, leading to paralysis and atrophy.
- Herpes causes skin lesions, oral lesions, STDs, and chickenpox, and is characterized by inflammation of the meninges caused by viral or bacterial infection.
- Symptoms of Meningitis include stiffness in the neck, headache, and fever.
- Parkinson disease is caused by a lesion in basal nuclei, characterized by muscular rigidity, resting tremor, general lack of movement, and a slow, shuffling gait.
- Encephalitis is inflammation of the brain caused by a virus or bacteria, with symptoms including fever, coma, and convulsions.
- Multiple sclerosis is a condition where the immune system attacks the brain and spinal cord.
- Myasthenia gravis is an autoimmune disorder affecting acetylcholine receptors, leading to muscle weakness, increased fatigue, and paralysis.
- Alzheimer disease involves loss of neurons in the cerebral cortex, with symptoms including general intellectual deficiency, memory loss, short attention span, moodiness, disorientation, and irritability.
Functions of the Nervous System
- Sensory Output: sensory receptors respond to stimuli.
- Integration: the brain and spinal cord process stimuli.
- The nervous system controls muscles and glands.
- Mental activity is controlled by the brain.
- The nervous system is responsible for maintaining homeostasis.
Main Divisions of the Nervous System
- Central Nervous System (CNS): consists of the brain and spinal cord.
- Peripheral Nervous System (PNS): consists of all neurons outside the CNS.
