Respuesta :
Answer:
Intermediolateral column of Thoracic and upper lumbar segments of spinal cord.
Explanation:
In order to answer, the question we need to understand the anatomy of Sympathetic nervous system.
Autonomic nervous system is the part of nervous system responsible for innervating smooth muscle, cardiac muscle and glandular cells.
It is further divided into 2 systems i.e. sympathetic system and parasympathetic system.
Sympathetic system is responsible for "fight-and-flight" responses. On the other hand, parasympathetic system mediates "rest-and-digest".
SYMPATHETIC SYSTEM ANATOMY:
Sympathetic system consists of 2 sets of neurons, the first one is called preganglionic neuron (presynaptic neuron) and the other one postganglionic neuron (postsynaptic neuron).
The cell body of preganglionic neurons of sympathetic system is located in the intermediolateral cell columns of thoracolumbar segment of spinal cord i.e. T1-12 and upper lumbar L1-2/3 segments. The axon of preganglionic neuron leaves the spinal cord and its fibers terminate on the cell body of postganglionic neuron in the paravertebral ganglia or prevertebral ganglia. From there, the fibers of postganglionic go on to terminate on the effector organ.
From the above discussion it is clear that,
The cell bodies of the preganglionic neurons in the sympathetic division are located in the Intermediolateral column of Thoracic and upper lumbar segments of spinal cord.
