Nervous System and Nerve Diseases

ANS and PNS

Peripheral Nervous system contains Ganglia and Nerves outside the Brain and spinal cord. PNS often exposed to toxins and mechanical injuries since it is not protected by skull or vertebral column. PNS is partitioned into Somatic Nervous System and Autonomic Nervous System (ANS). The predominant function is to carry signals from Central Nervous System to all other organs of the body.

ANS controls certain body function such as blood pressure and heart rates without any conscious effort of the person. Two neurotransmitters used to interact within the autonomic nervous system are Acetylcholine and Norepinephrine. Other functions are body temperature, digestion, urination, defecation and production of body fluids.
