The diaphragm is a thin skeletal muscle that sits at the base of the chest and separates the abdomen from the chest. It contracts and flattens when you inhale. This...
An optical device in a camera or telescope that regulates the amount of light that enters the lens or optical system. The diaphragm consists of a disk with a circular opening of variable diameter.
The diaphragm is a musculotendinous structure with a peripheral attachment to a number of bony structures. It is attached anteriorly to the xiphoid process and costal margin, laterally to the 11th and 12th ribs, and posteriorly to the lumbar vertebrae.
The diaphragm is a muscle that helps you inhale and exhale (breathe in and out). This thin, dome-shaped muscle sits below your lungs and heart. It’s attached to your sternum (a bone in the middle of your chest), the bottom of your rib cage and your spine.
diaphragm, dome-shaped, muscular and membranous structure that separates the thoracic (chest) and abdominal cavities in mammals; it is the principal muscle of respiration.
The diaphragm is a parachute-shaped fibrous muscle that runs between the chest and abdomen, separating these two large cavities. It is asymmetric, as its right dome is larger than the left dome. The diaphragm has openings that allow certain structures to span the chest and abdominal cavities.
What is the Diaphragm: Definition. The thoracic diaphragm is a large, flat muscle that plays a vital role in the respiratory system, and is located just beneath the two lungs, dividing the chest cavity from the abdominal cavity [1]. With its characteristic dome shape, it is the primary respiratory muscle, also supporting the lungs and heart [2].
The diaphragm is a barrier between the thoracic and abdominal cavities, preventing abdominal organs from protruding into the chest cavity. It plays a vital role in maintaining intra-abdominal pressure by contracting along with the anterolateral abdominal muscles.
The diaphragm is a dome-shaped sheet of skeletal muscle that divides the thoracic cavity from the abdominal cavity. That may sound simple, but in fact, the diaphragm is so much more than just a sheet of muscle. In fact, every breath you take is thanks to your diaphragm! Ok, so let’s begin by looking at the general structure of the diaphragm.
