In mechanics, a diaphragm is a sheet of a semi-flexible material anchored at its periphery and most often round in shape. It serves either as a barrier between two chambers, moving slightly up into one chamber or down into the other depending on differences in pressure , or as a device that vibrates when certain frequencies are applied to it.
The muscle fibres of the diaphragm radiate outward from the central tendon. While the diaphragm is one muscle, it is composed of two distinct muscle regions: the costal, which serves as the driver in the work of breathing, and crural diaphragm, which serves as an "anchor;" attaching the muscle to the lower ribs and lumbar vertebrae.
The muscles of respiration are the muscles that contribute to inhalation and exhalation, by aiding in the expansion and contraction of the thoracic cavity. The diaphragm and, to a lesser extent, the intercostal muscles drive respiration during quiet breathing. The elasticity of these muscles is crucial to the health of the respiratory system ...
The muscles of forceful breathing (inhalation and exhalation). The color code is the same as on the left. In addition to a more forceful and extensive contraction of the diaphragm, the intercostal muscles are aided by the accessory muscles of inhalation to exaggerate the movement of the ribs upwards, causing a greater expansion of the rib cage.
Animation of diaphragmatic breathing with the diaphragm shown in green. Diaphragmatic breathing, abdominal breathing, belly breathing, [1] or deep breathing, [2] is breathing that is done by contracting the diaphragm, a muscle located horizontally between the thoracic cavity and abdominal cavity.
The lat pulldown machine is an essential piece of equipment for anyone looking to build a wide, strong back. This machine specifically targets the latissimus dorsi muscles, which run along the ...
An air pump or a flexible diaphragm (usually motor-driven) varies the air pressure inside the tank, in continuous alternations, lowering and raising the air pressure in the cylinder. This causes the patient's chest to rise and fall, stimulating inhalation and exhalation through the patient's nose and mouth (which are outside the cylinder ...
