Study Notes
Diaphragm Innervation
- The phrenic nerves (C3-C5) are crucial for diaphragm function.
- Damage to C3, C4, or C5 nerves can lead to diaphragmatic paralysis, impacting breathing.
Diaphragm Function
- The diaphragm's primary function is to aid in respiration by contracting and relaxing, thus changing the volume of the thoracic cavity.
Phrenic Nerve Role in Respiration
- The phrenic nerves carry motor impulses to the diaphragm, enabling its rhythmic contractions crucial for inhalation and exhalation.
