what might happen to the human body if one part of the nervous system fails to carry out its function properly?

Sagot :

The central nervous system is composed of the brain and the spinal cord. It is primarily responsible for ensuring that the body responds accordingly to stimuli, with or without the brain's response. Hence, the CNS controls our movements, emotions and desires. Our breathing, release of hormones, temperature and many more are other autonomic functions as well which are regulated by the CNS. Losing this means losing some or all of these functions.

Stroke

A common impairment of the CNS results from someone having a stroke. A portion of the brain is either diseased or blocked resulting in the loss of function of half of the body. A stroke patient typically loses sensations on the affected body part and consequently muscle loss as well. Hence, when doctors deal with the aftermath of a stroke, a patient has to undergo physical therapy session in an attempt to recover the lost functions.

Quadriplegia

Another example of when the CNS does not function is in the case of quadriplegics. If the nerves in the neck are damaged for whatever reason, it could result in the paralysis from the neck down. This means that unlike a stroke patient, this patient would lose function on all four limbs. Usually, if this is the case, there is very little hope of recovering the functions of the limbs.

Parkinson's Disease

One other common CNS disease is having Parkinson's disease. A patient who has this gradually loses mobility functions as parts of the brain become degenerated.  

Tumors

Tumors, whether cancerous or not are usually dangerous if it occurs in the brain. That is because as the tumor grows, it occupies space meant for the brain in a limited space. This results in parts of the brain being pressed. In turn, neurological symptoms almost always accompany any brain tumor.

Taking care of the CNS is critical because any disease can result in major loss of bodily functions.
