these two structures take part in complex control loops that govern certain aspects of movement and, when substantia nigra cells degenerate, these loops are disrupted and movements become unregulated, producing the symptoms of Parkinson's disease.

Which results from a degeneration of dopamine-releasing neurons of the substantia nigra and leads to symptoms such as persistent tremors at rest forward-bent walking posture and shuffling gate?
Parkinson's Disease
What is the midbrain?
The midbrain is the smallest region of the brain that acts as a sort of relay station for auditory and visual information. The midbrain controls many important functions such as the visual and auditory systems as well as eye movement. Portions of the midbrain called the red nucleus and the substantia nigra are involved in the control of body movement. The darkly pigmented substantia nigra contains a large number of dopamine-producing neurons are located. The degeneration of neurons in the substantia nigra is associated with Parkinson's disease.
What does the pons control in the brain?
The functions of the pons include arousal, assisting in controlling autonomic functions, relying sensory information between the cerebrum and cerebellum and sleep. The structure of the brain called the "midbrain" is located just above the spinal cord and is the smallest region of the brain. It controls some very important functions, such as acting as sort of a relay station for auditory and visual information. The midbrain controls the visual and auditory systems as well as eye movement. Portions of the midbrain called the red nucleus and the substantia nigra are involved in the control of body movement. The darkly pigmented substantia nigra contains a large number of dopamine-producing neurons. The degeneration of neurons in the substantia nigra is associated with Parkinson's disease.
Where is dopamine located?
Dopamine is produced in the substantia nigra of the brain as well as in the ventral tegmental area (VTA) of the midbrain and the arcuate nucleus of the hypothalamus.
Name the disease which infectors motor neurons at the NMJ?
Poliomyelitis....
What happens when the substantia nigra is damaged?
Degeneration of neurons especially in substantia nigra of both sides might cause Parkinson's disease.
Why do people get parkinsons disease?
It is a degeneration of dopaminerge neurons in substantia nigra in the brain, which results in less excitatory and inhibitory dopamine to the basal ganglia. The reasons for the degeneration of neurons is yet unknown. It usually begins at the age of 40. Parkinson's sometimes runs in families, a

Parkinson's Disease
Does Parkinson's disease affect the brain stem?
No, parkinson's affects the dopaminergic neurons of the substantia nigra, which is part of the mid-brain.

What is LAS disease?
ALS, often referred to as "Lou Gehrig's Disease," is a progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord. Motor neurons reach from the brain to the spinal cord and from the spinal cord to the muscles throughout the body. The progressive degeneration of the motor neurons in ALS eventually leads to their death.
What are parkinson disease symptoms?
The precise causes of all types of Parkinson disease are not known, but the common path of disease involves a loss of neurons in a part of the brain called the substantia nigra. These cells produce and release dopamine and are crucial for allowing the initiation of movement, which is one of the faculties that can be severely impaired in patients with the disease. The classic signs and symptoms of Parkinson disease are often remembered by the mnemonic TRAP: * Tremor at rest * Rigidity * Akinesia (actually dyskinesia, which is the presence of involuntary movements) * Postural instability There is considerable research evidence that drinking alcohol (beer, wine, or liquor) reduces the risk of developing the disease.

What disease causes neurons in the brain to die?
Alzheimer's disease
What is the disease of Parkinson's?
Parkinson Disease is a gradual neurodegenerative disorder caused by motor deficits which is due to dopaminergic neurons loss in the substantia nigra and the production of lewy bodies. In this case the facial muscles are affected including upper and lower extremities and this also leads to a condition name parkinsonism.

What is the medical term meaning hardening and degeneration of the myelin sheath?
Muscular sclerosis is hardening and degeneration of the myelin sheath. Muscular sclerosis Multiple sclerosis is a disorder marked by destruction of the myelin sheath on neurons in the CNS and replacement with hard scar tissue.
