Question

All of the following are spinal plexuses EXCEPT ________.
A) lumbar plexus
B) brachial
C) thoracic plexus
D) cervical plexus

The thoracic nerves do not form a plexus. The thoracic spinal nerves (T1-T12) primarily exit the spine and go directly to their target areas without forming a complex network or plexus like the cervical, brachial, and lumbar plexuses do.
