A regulatory framework Although common in other process manufacturing industries (e.g., food and chemicals), continuous processing is at a nascent stage in the pharmaceutical industry, where batch manufacturing is the prevailing mode.
When the motor neurons in the brainstem are affected (bulbar ALS), the muscles used in speech and swallowing are impaired. ALS only affects muscles that are moved voluntarily (such as those in the mouth or arm) and does not impact those muscles involved in involuntary movements, such as digestion.
Amyotrophic lateral sclerosis (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. When the motor neurons die, the ability of the brain to initiate and control muscle movement is lost.
