Behind Each Breath, an Underappreciated Muscle
Some muscles get all the glory. Bodybuilders show off their swollen triceps; sprinters flash their sharp-edged calves. But deep inside all of us, a sheet of muscle does heroic work in obscurity. In order to breathe in, we must flatten the dome-shaped diaphragm; to breath out, we let it relax again. The diaphragm delivers oxygen to us a dozen times or more each minute, a half-billion times during an 80-year life. “We are completely dependent on the diaphragm,” said Gabrielle Kardon, a biologist at the University of Utah. “But we take it for granted every moment we’re breathing.” To Dr. Kardon, the diaphragm is not just underappreciated but puzzling. All mammals, from platypuses to elephants, have…Featured
The diaphragm – More than an inspired design
There is arguably no other muscle in the human body that is so central literally and figuratively to our physical, biochemical and emotional health as the diaphragm. From its most obvious role in respiration, to its less obvious roles in postural stability, spinal decompression, fluid dynamics, visceral health and emotional regulation, the diaphragm has a repertoire of function that is broad by any muscle's standards.
The Diaphragm: Remarkable Piston of the Body
The diaphragm is a singular muscle with fibers unlike any other in the body. It moves equally with voluntary and involuntary movement. We may move our diaphragm deliberately to relax and take deep breaths, but it will also move on its own, structuring the rhythm of the body.

Dr. Ginsburg Explains the Human Diaphragm
What's the human diaphragm, you ask? Dr. Mark Ginsburg, Director of the world's first Diaphragm Center, explains.
Excerpt: 'The Soul Of Medicine'
The problem was obvious, and one glance downward at the diaphragm explained everything. The diaphragm is a thick sheet of muscle and fiber lying transversely across the middle of the body, separating the chest cavity from the abdomen. Its only openings are three snug apertures that allow the esophagus and the large artery and vein called the aorta and vena cava to traverse it; it is otherwise like an intact, inviolate curtain of flesh through which nothing can pass. That may describe your diaphragm or mine, but not the unique one possessed by Jimmy Tyson.
In Glam of Diaphragms
Who would of thought one of the most asymmetrical muscles of our body has probably the most impact on us. From back problems, to posture, to our well being, our diaphragm in a way sets the tone of whats going on around us and has links to many different bodily systems. I’d like to dive in first on where exactly it is and some anatomical implications it has. Its amazing and ironic that it is literally placed at the center of our body. You can’t get anymore center than our diaphragm. Its smack dab right at the bottom of our rib cage and underneath our lungs and in front of our spine. The diaphragm is almost like a septum that regulates airways and separates the chest cavity and abdominal cavity.
Learning diaphragmatic breathing
Relearning how to breathe from the diaphragm is beneficial for everyone. Diaphragmatic breathing (also called "abdominal breathing" or "belly breathing") encourages full oxygen exchange — that is, the beneficial trade of incoming oxygen for outgoing carbon dioxide. Not surprisingly, this type of breathing slows the heartbeat and can lower or stabilize blood pressure.
The diaphragm: a hidden but essential organ for the mammal and the human
The diaphragm is the only organ which only and all mammals have and without which no mammals can live. The human is the only mammal which keeps the diaphragm parallel to the ground even during locomotion. Abdominal breathing mode maximizes the diaphragmatic motion using abdominal muscles, and control precisely exhaled air velocity.
The diaphragm: two physiological muscles in one
To the respiratory physiologist or anatomist the diaphragm muscle is of course the prime mover of tidal air. However, gastrointestinal physiologists are becoming increasingly aware of the value of this muscle in helping to stop gastric contents from refluxing into the oesophagus. The diaphragm should be viewed as two distinct muscles, crural and costal, which act in synchrony throughout respiration.
Understanding Your Body: What is a Diaphragm and Its Crucial Role in Breathing and Health
The diaphragm plays a crucial role in breathing by contracting and relaxing to change the volume of the chest cavity. When the diaphragm contracts, it flattens and moves downward, allowing the lungs to expand and fill with air. This process is known as inspiration. When the diaphragm relaxes, it returns to its dome-shaped position, and the lungs deflate, releasing air from the body. This process is known as expiration.

The diaphragm is an unpaired, dome shaped skeletal muscle that is located in the trunk. It separates the thoracic and abdominal cavities from each other by closing the inferior thoracic aperture.
Planet Singer
The diaphragm, also known as thoracic diaphragm, is a C shaped structure of skeletal muscle and fibrous tissue that is located across the bottom of the thoracic cavity. It is like a dome oriented upwards and separates the thoracic cavity that contains the heart and lungs, from the abdominal cavity. This muscle is located just below the lungs, having a primary function in breathing, so it is essential for singing. It is a little asymmetric because beneath the right half there is the large liver and the left side is lower because of the presence of the heart. Unlike the rest of the muscles of the body, this is not completely fixed and bridged to the walls, it is mobile, making it a complex structure.
TeachMe Anatomy
The diaphragm is a double-domed musculotendinous sheet, located at the inferior-most aspect of the rib cage. It serves two main functions: Separates the thoracic cavity from the abdominal cavity (the word diaphragm is derived from the Greek ‘diáphragma’, meaning partition). Undergoes contraction and relaxation, altering the volume of the thoracic cavity and the lungs, producing inspiration and expiration.
