The diaphragm contains a few key muscular pieces: the sternal, costal, and lumbar sections. Just about every element has distinctive origins but all converge in the central tendon, Doing the job alongside one another to aid the diaphragm’s motion in the course of respiration.
Perhaps the most recognized mnemonic among anatomy college students really worries the innervation from the diaphragm. Understand ' C3, four, five retains the diaphragm alive!' and you will under no circumstances overlook the motor innervation yet again!

The diaphragm’s muscle mass fibers are integral to its functionality as a Main respiratory muscles. These fibers converge in the direction of a central tendon, which acts as an anchor stage and facilitates the diaphragm’s motion in the course of inhalation and exhalation.
Framework The diaphragm is largely composed of muscle and fibrous tissue. The central tendon is a significant Component of the diaphragm that anchors the diaphragm to your ribs.
The diaphragm divides the thoracic and abdominal cavities. As a result, any structure that go in between The 2 cavities will pierce the diaphragm.
As well as its part in respiration, the diaphragm also plays a role in preserving the strain gradient amongst the thoracic and abdominal cavities. It can help to forestall the organs throughout the abdominal cavity from being pushed up into the thoracic cavity.
Understanding the diaphragm’s anatomical situation and its divisions assists recognize its function in respiration as well as other bodily features. These structural information variety The premise for how it operates in each typical and pressured ailments.
Activation of your phrenic nerve contributes to diaphragm contraction during inhalation, letting for a rise in thoracic volume. This method is controlled by a posh neural network involving website phrenic motor neurons, which happen to be the final output for diaphragm muscle mass force generation.
Besides the situations mentioned over, the diaphragm can also be impacted by other problems for instance neuromuscular Diseases, bacterial infections, and inflammation. Neuromuscular Ailments, for example myasthenia gravis and spinal twine accidents, can impair the functionality of the diaphragm and bring about respiratory troubles.
Diaphragmatic paralysis is because of an interruption in its anxious supply. This will occur inside the phrenic nerve, cervical spinal wire, or even the brainstem. It is actually most often on account of a lesion of the phrenic nerve:
The muscle mass fibres from the diaphragm Blend to kind a central tendon. This tendon ascends to fuse Using the inferior area with the fibrous pericardium.
