36
Q

Trace the pathway of the sympathetic nervous system to the BODY WALL.

A

Lateral horn –> Ventral root –> Spinal nerve –> Ventral ramus –> White ramus communicons –> Sympathetic trunk –> Para-vertebral ganglion (synaps) –> Grey ramus communicons –> Ventral or Dorsal rami –> Body Wall Targets (Blood vessels, arrector pilli muscles, sweat glands)

37
Q

Trace the pathway of the sympathetic nervous system to the THORACIC ORGANS.

A

Lateral horn –> Ventral root –> Spinal nerve –> Ventral ramus –> White ramus communicons –> Sympathetic trunk –> Para-vertebral ganglion (synaps) –> Cardiac/Pulmonary nerves –> Heart/Lungs

38
Q

Trace the pathway of the sympathetic nervous system to the ABDOMINAL ORGANS.

A

Lateral horn –> Ventral root –> Spinal nerve –> Ventral ramus –> White ramus communicons –> Sympathetic trunk –> Splanchnic nerve –> Pre-vertebral ganglion –> Abdominal/Pelvic organs

39
Q
