1. Phrenic nerve

   The phrenic nerve is a mixed motor/sensory nerve which originates from the C3-C5 spinal nerves in the neck. The nerve is important for breathing because it provides exclusive motor control of the diaphragm, the primary muscle of respiration. In humans, the right and left phrenic nerves are primarily supplied by the C4 spinal nerve, but there is also contribution from the C3 and C5 spinal nerves. From its origin in the neck, the nerve travels downward into the chest to pass between the heart and lungs towards the diaphragm. In addition to motor fibers, the phrenic nerve contains sensory fibers, which receive input from the central tendon of the diaphragm and the mediastinal pleura, as well as some sympathetic nerve fibers. Although the nerve receives contributions from nerves roots of the cervical plexus and the brachial plexus, it is usually considered separate from either plexus. The name of the nerve comes from Ancient Greek phren 'diaphragm'.

1. phrenic nerve

   The phrenic nerve is a major nerve of the human body, originating from the neck and descending through the thorax to reach the diaphragm. It plays an essential role in controlling the contraction of the diaphragm, hence, facilitating the process of breathing. Damage to the phrenic nerve can result in difficulties with respiration. There are two phrenic nerves - right and left - on either side of the body.

1. Phrenic nerve

   The phrenic nerve is a nerve that originates in the neck and passes down between the lung and heart to reach the diaphragm. It is important for breathing, as it passes motor information to the diaphragm and receives sensory information from it. There are two phrenic nerves, a left and a right one. The phrenic nerve originates mainly from the 4th cervical nerve, but also receives contributions from the 5th and 3rd cervical nerves in humans. Thus, the phrenic nerve receives innervation from parts of both the cervical plexus and the brachial plexus of nerves. The phrenic nerves contain motor, sensory, and sympathetic nerve fibers. These nerves provide the only motor supply to the diaphragm as well as sensation to the central tendon. In the thorax, each phrenic nerve supplies the mediastinal pleura and pericardium.

1. Phrenic Nerve

   The motor nerve of the diaphragm. The phrenic nerve fibers originate in the cervical spinal column (mostly C4) and travel through the cervical plexus to the diaphragm.
