The Vagus Nerve.


What muscle does the phrenic nerve innervate?

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.


What are the attachments of the diaphragm and what nerve innervates it?

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.

Which cranial nerve innervates the diaphragm muscle?

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).

What are hiccups classified as?

What are Hiccups?Hiccups are involuntary spasms of the diaphragm muscles that draw air into the lungs. Hiccups occur when the diaphragm becomes irritated, causing it to contract suddenly and involuntarily. As the diaphragm contracts, the opening between the vocal cords (glottis) snaps shut, causing the hiccup sound. Hiccups are usually caused when the nerve that extends from the neck to the chest is irritated (the phrenic and vagus nerves).


What stimulates the diaphragm?

The nerve that stimulates the diaphragm to contract arises from the cervical plexus. When people have diaphragmatic pacemakers, an electrical stimulation is used to help with their breathing.


Deep muscle of the thorax that promote the inspiratory phase of breathing?
