Question
Which statement is TRUE regarding the sympathetic division of the autonomic nervous system? (answer is not B)
Most sympathetic preganglionic fibres secrete noradenaline (norepinephrine).
Sympathetic postganglionic neurons have their cell bodies in the spinal cord at T1 to L2.
Epinephrine is secreted by some parasympathetic postganglionic fibers.
Sympathetic fibers extend from the thoracic to the sacral regions of the spinal cord.

b)Sympathetic postganglionic neurons have their cell bodies in the spinal cord at T1 to L2.
c)Epinephrine is secreted by some parasympathetic postganglionic fibers.
d)Sympathetic fibers extend from the thoracic to the sacral regions of the spinal cord.
Explanation / Answer
the autonomic nervous system is divided into two -
sympathetic nervous system
parasympathetic nervous system
the preganglionic neurons are situated in lateral gray horns of 12 thoracic and first two lumbar segments of spinal cord. Preganglionic fibers leave the spinal cord and terminate in the postganglionic neurons, which are situated in the sympathetic ganglia.
so the answer is (d) sympathetic fibres extend from the thoracic to the sacral regions of spinal cord
