The sympathetic division of the ANS arises from the cervical region of the spinal cord.
<h3>What is a sympathetic nervous system?</h3>
The sympathetic nervous system is part of the autonomic nervous system, along with the parasympathetic nervous system.
The sympathetic pathway can be divided into three following components:
•The preganglionic neurons,
•The sympathetic ganglia,
•The postganglionic neurons.
It is essential for preparing the body for emergency response in endangering situations, also known as the “fight-or-flight” response.
To prepare the body for this type of response, the sympathetic system activates numerous complex pathways enable the adequate response to a threat or trauma.
Some of these physical effects include: faster breathing, increased heart rate and blood pressure, dilation of pupils, redirection of blood flow to important organs (e.g. brain and muscles) and increased sweating.
