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 else can I help you with?
What nerves innervate the diaphragm?
The phrenic nerve, arising from C3,C4,C5. Damage to the brachial plexus can result in temporary or permanent paralysis of the diaphragm
What nerve stimulates the diaphragm?
ulna
What is the major nerve stimulating the diaphragm?
While reading " Structure and Function of the Human Body" I believe the correct answer is the phrenic nerve. Hope this helps. the nerve that stimulates is the phrenic nerve but it arises from the cervical plexus
From what plexus does the phrenic nerve arise?
The phrenic nerve arises from the cervical plexus, specifically from nerve roots C3, C4, and C5. It travels down through the thorax to innervate the diaphragm, playing a crucial role in breathing.
Is the phrenic nerve a mixed nerve?
Yes, the phrenic nerve is a mixed nerve. It contains both motor and sensory fibers. The phrenic nerve plays a crucial role in controlling the diaphragm, the main muscle involved in breathing.
Which muscle is innervated by the phrenic nerve?
Diaphragm
What nerve innervates the diaphragm causing it to contract?
Phrenic
What nerve causes the deaphragm to contract and initiate inhalation?
The phrenic nerve is responsible for stimulating the diaphragm to contract and initiate the process of inhalation. It arises from the spinal cord and plays a crucial role in controlling breathing by sending signals to the diaphragm muscle.
What are the two parts on exhale which receive nerve inpulses?
One is the phrenic nerve. The other is the diaphragm muscle relaxing.
Which spinal plexus gives rise to the phrenic nerve and what organ does this nerve supply?
The phrenic nerve arises from the cervical plexus (C3-C5) and supplies the diaphragm, which is the primary muscle involved in breathing.
Diaphragm contractions are regulated by what nerve?
The diaphragm's contractions are regulated by the phrenic nerve. A diaphragm are the muscle that inserts on the central tendon.
The phrenic nerve arises from the?
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.
