phrenic nerves
Motor innervation of the diaphragm comes from the phrenic nerves (C3-C5). These nerves innervate the diaphragm from its abdominal surface after they penetrate it.

What nerves pass through the diaphragm?

The phrenic nerve passes through the diaphragm. In the intact mediastinum, the phrenic nerve runs here, just beneath the pleura. On the left side, the course of the phrenic nerve is similar: in its course in the mediastinum it passes over the aorta, the pulmonary trunk, and the left ventricle.

What passes through diaphragm at T8?

The inferior vena cava passes through the diaphragm at the vena caval foramen. This aperture is located in the central tendon at the level of T8. Sometimes the phrenic nerve may also be found passing through this aperture.

Are the lungs attached to the diaphragm?

The diaphragm is attached to the base of the sternum, the lower parts of the rib cage, and the spine. As the diaphragm contracts, it increases the length and diameter of the chest cavity and thus expands the lungs.

What are the three openings in the diaphragm?

There are a number of openings in the diaphragm through which structures pass between the thorax and abdomen. There are three large openings — one for the aorta, one for the esophagus, and one for the inferior vena cava (the caval opening), plus a series of smaller ones.

Is the stomach above or below the diaphragm?

Location. Your heart, lungs, and the upper part of your esophagus (food pipe) are in the thoracic cavity above the diaphragm. Your lower esophagus, stomach, intestines, liver, and kidneys are below the diaphragm, in your abdominal cavity.

Does the phrenic nerve pass through the diaphragm?

The phrenic nerve as it passes through the thorax to supply the diaphragm. The phrenic nerve emerges from the cervical plexus, with the right brachial plexus shown here. From its origin in the neck, the nerve travels downward into the chest to pass between the heart and lungs towards the diaphragm.

Can you live without diaphragm?

The diaphragm is the only organ which only and all mammals have and without which no mammals can live. The human is the only mammal which keeps the diaphragm parallel to the ground even during locomotion.
