Question

Quizplus · Accepted Answer

The anterior rami of the spinal nerves do not form nerve plexuses in the thoracic region. Instead, each thoracic spinal nerve gives off intercostal nerves that supply the intercostal muscles and the skin of the thorax. The other regions (cervical, lumbar, and sacral) have nerve plexuses that provide a more complex network of nerves to supply the limbs and other structures in those regions.
