The dipahragm is innervated by the phrenic nerve. This nerve responds to the stimulus sent by the a very particular set of neurons located in the medulla. The main ones are called VRG and DRG. Of these the VRG sends signals to the diaphragm to contract, when the signal is not "on" then the diaphragm relaxes. DRG modulates the depth of breath. There is another group called the pneumotaxic center found in the ponds; this group keeps the VRG in check. If the frequency of respiration becomes too great the pneumotaxic center inhibits depolarization of the VRG for a while in an attempt to restore a "normal" breathing pattern
What else can I help you with?
Does the diaphragm need to go down to breath in?
The diaphragm moves down and contracts, flattening itself, when you inhale.
Do the muscles of the diaphragm relax during inspiration?
No, the muscles of the diaphragm do not relax during inspiration; rather, they contract. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and allowing air to be drawn into the lungs. This contraction is crucial for effective inhalation, and it is complemented by the action of the intercostal muscles.
How do you speak from your diaphragm?
To speak from your diaphragm, take a deep breath where your stomach expands, rather than your chest. This will engage your diaphragm, allowing for better breath control and projection when speaking. Practice breathing exercises and be mindful of your breathing while speaking to strengthen this technique.
Does diaphragm have any desiesses?
Yes, the diaphragm can be affected by disorders or conditions such as paralysis, diaphragmatic hernia, or diaphragm muscle weakness. These conditions can impact the ability of the diaphragm to properly contract and relax, leading to difficulties in breathing and other respiratory functions.
When the diaphragm contracts where does the air go?
When the diaphragm contracts the air is pushed out to the lungs and we breath. also when you project your voice you diaphragm rises causing you to take deeper breaths- this is why you breath more when you project your voice\sing etc
Does exhalation occur when the diaphragm and rib cage muscles relax?

What do the muscles do when you breath out?
They relax. Except when you forcefully exhale, in which case the contracting abs help push the diaphragm up towards the chest cavity, and squeeze some extra air out of the lungs.
What layer of muscles move up and down when you breath?
The diaphragm is a muscle that moves or pushes up your lung when you exhale and down when you inhale in order to allow more space for oxygen to fill your lung. Also, your chest expands as you breath in and relax as you exhale.
How the diaphragm helps the lungs?
Your diaphragm contracts and expands when you breath. When the diaphragm contracts, air rushes into the lungs. When the diaphragm relaxes, air is exhaled.
When the rib muscles and diaphragm relax and the chest cavity becomes what?
When the diaphragm and muscles of the rib cage relax, the thoracic cavity becomes smaller. These changes occur during exhalation.
