The autonomic nervous system
The autonomic nervous system ensures that there is a balance between tension and relaxation.
The parasympathetic nervous system that relaxes the body (while massaging)
The nervous system is a large network of nerve cells, which are in contact with each other through long offshoots and billions of contact points. A nerve cell consists of a cell body that contains shorter threads (that pick up impulses) and longer threads (that transport information to other nerve cells, muscle cells or glandular cells). Those threads are the offshoots or nerve fibres. A bundle of a large number of long offshoots combine to form a nerve. You could compare a nerve with an antenna: it picks up messages and passes them on again. The message travels at lightning speed to e.g. another nerve cell or to a muscle. There are 3 types of nerve connections: nerve connections that control the muscles, nerve connections that transmit messages from the body to the brain (such as pain and cold), and nerve connections that control the organs within the body. These travel in two directions.
The peripheral nervous system is made up of all spinal and cranial nerves to and from the sensory organs, muscles, joints and skin. The peripheral nervous system is responsible for movement and transmits sensory information to the central nervous system.
The autonomic nervous system:
The autonomic nervous system forms, the balancing scales of the body's internal organs, so to speak. The autonomic nervous system ensures that there is a balance between tension and relaxation. The autonomic nervous system can be divided into two sections:
Peripheral nerves (examples):
Plexus brachialis (shoulder/arm) C4-Th1
Plexus lumbalis (stomach/inner thigh) L1-L3
Sacral plexus (buttock region, front/rear thigh) L4-S5
nervus axillaris
nervus brachialis
nervus radialis
nervus ulnaris
nervus ischiadicus
nervus tibialis
nervus peroneus
