The diaphragm is attached to the xiphoid process (Sternum), the lower six costal cartilages (ribs) and the upper three lumbar vertebrae (back bone), and the fibres converge to a central median tendon.
It is supplied by the phrenic nerve.
Phrenic
C 3,4 and 5. ( 345 keeps the diaphragm alive )
The entire motor supply to the diaphragm arises from the anterior rami of segments C3-C5 of the spinal cord, and runs within the right and left phrenic nerves. In addition, pain and proprioception for the diaphragm also run within the phernic nerve, although not entirely. Sensory nerve supply for the diaphragm also is supplied by the intercostal nerves (arises from T5-T11) and the subcostal nerves (T12).
Phrenic nerves from brachial and cervical plexus.
The phrenic nerve, which arises from the C3-C5 nerve roots in the cervical spine, innervates the diaphragm muscle and controls its function. Dysfunction of the phrenic nerve can impair breathing and lead to respiratory issues.
The phrenic nerve innervates the diaphragm which is our main breathing muscle. It is a broad flat sheet that encircles our lower ribcage and separates our thoracic from our abdominal cavities. The phrenic nerve arises from the C3-C5 level of our vertebrae. In the event of a broken neck, that is often the determining factor whether someone will die (from an inability to breathe) or is just paralyzed.
The testicular nerve and the nerve to the cremaster innervate the vas deferens in the spermatic cord.
The phrenic nerve arises from the spinal cord at C3, C4, and C5 nerve levels. It originates from the cervical plexus and innervates the diaphragm muscle, playing a crucial role in controlling breathing.
The nerve that innervates the abductor pollicis brevis in most people is the median nerve.
Cervical Plexus- The major motor branch of this plexus is the phrenic nerve which from C3 via C4 and passes into the thoracic cavity in front of the first rib to innervate the diaphragm. "C3 C4 C5, keep the diaphragm alive." <3 Hope it helps :)
The cranial nerve that innervates the ear is the vestibulocochlear nerve (CN VIII). It has two branches: the vestibular nerve that controls balance and the cochlear nerve that controls hearing.
