Question 17

Autonomic motor commands pathway from the spinal cord

Answer 17

Visceral motor region ventral column –>

Ventral root –>

Spinal nerve –>

White ramus of rami communicans –>

Sympathetic ganglion:
a) Synapse and become post ganglionic –> Thoracic cavity visceral organs

OR

b) Continue as preganglionic –> Collateral ganglia –> Post ganglionic closer to Abdominal pelvic viscera
