The sympathetic nerve soft silicone anatomy model shows the autonomic nervous system, sympathetic and parasympathetic nerves located in the trunk, sympathetic in yellow, parasympathetic in white.
In addition, schematic description of model structure: A total of 53 parts are displayed. The autonomic nervous system (autonomic nervous system) controls visceral activity and is involved in glandular secretion, smooth muscle contraction, and heartbeat, respiratory, and reproductive functions. The autonomic nervous system consists of sympathetic and parasympathetic nerves. The sympathetic trunk is the most important part of the sympathetic nerve. It is located on both sides of the spine and consists of many sympathetic trunk ganglia and intersegmental branches. The sympathetic trunk is connected to the spinal nerves by the grey and white branches.
