The phrenic nerve originates from the cervical plexus. The cervical plexus is formed by the anterior rami of the first four cervical nerves (C1 - C4). The phrenic nerve (mainly from C3 - C5) is an important nerve that innervates the diaphragm, which is crucial for breathing. The brachial plexus (C5 - T1) is related to the upper limb innervation. The lumbar plexus (L1 - L4) and sacral plexus (L4 - S4) are involved in the innervation of the lower limb and pelvic region.
