This light comes from the microscope's light source, and is gathered by the condenser, before being regulated by the diaphragm, then passing through the specimen. Motor innervation of the diaphragm comes from the phrenic nerves (C3-C5).These nerves innervate the diaphragm from its abdominal surface after they penetrate it. It has three openings: the esophagus, the inferior vena cava and the aorta. Suggested further reading: Courtney, R. The functions of breathing and its dysfunctions and their relationship to breathing therapy . The most common conditions include hernias and nerve damage from surgery or an accident. It also allows the esophagus to run through the esophageal hiatus so it can connect the pharynx to the stomach [23]. Start studying Thoracic apertures and diaphragm. The three main openings in the diaphragm (Figs 10, 11) are: 1 the aortic (at the level of T12) which transmits the abdominal aorta, the thoracic duct and often the azygos vein; 2 the oesophageal (T10) which is situated between the muscular fibres of the right crus of the diaphragm and transmits, in addition to the oesophagus, branches of the left gastric artery and vein and the two vagi; 3 the opening for the inferior vena cava (T8) which is placed in the central tendon and also transmits the right phrenic nerve. Additionally, there are some small openings in the central tendon for certain veins [5]. Function. Prevalence of the juxtaphrenic peak after upper lobectomy. There are two popular types of diaphragm namely rigid diaphragm and semi-rigid Diaphragm. When we say diaphragm, we generally refer to the thoracic diaphragm that helps in breathing.

The pleuroperitoneal membrane originates from the body wall, dorsal mesentery of the oesophagus and septum transversum (Figure 1A). All these blood vessels connect and open into each other (anastomose) to ensure proper blood supply to the diaphragm [5]. The medullary inspiratory neuron (responsible for regulating breathing) sends information to the diaphragm via this nerve, enabling us to breathe in. The three main openings in the diaphragm (Figs 10, 11) are: 1 the aortic (at the level of T12) which transmits the abdominal aorta, the thoracic duct and often the azygos vein;. The phrenic nerve, originating at the C3-C5 vertebral level, provides motor supply to the diaphragm [2], and controls its movement [15]. The left side of the diaphragm is innervated by the left phrenic nerve and the right side by the right phrenic nerve [3]. Sometimes, this abnormally contracted muscle may make it difficult to breathe deeply, leading to other problems [24]. The right phrenic vein drains into the inferior vena cava, and the left phrenic vein empties into the left renal vein, suprarenal vein, or inferior vena cava [5]. The three primary openings are: Caval opening (vena caval hiatus) at the 8th vertebral level: Allows the inferior vena cava [9] and the right phrenic nerve branches [11] to pass through.

Structures passing through three major openings of the diaphragm. What Happens to it during exhalation: Once the gas exchange takes place within the alveoli, the CO2-rich air fills the alveoli. It is a dome-shaped structure which is made up of the muscle fibres at the periphery and a central tendon in the centre. The aortic opening (aortic hiatus), through which the aorta, thoracic duct, and azygous vein pass. Otherwise, the diaphragm will be considered as a rigid diaphragm. However, it still interferes with the lungs ability to take in air, as the muscle cannot contract to its full capacity [25]. As the diaphragm contracts, it also increases the volume of the thoracic cavity, making room for the inflated lungs [1].
