The costodiaphragmatic recess, also called the costophrenic recess or phrenicocostal sinus, [1] is the posterolateral fringe of the pleural space, a potential space around the lung inside the pleural cavity. It is located at the acutely angled junction ("reflection") between the costal and diaphragmatic parietal pleurae, and is interpreted two ...
A pleural effusion is accumulation of excessive fluid in the pleural space, the potential space that surrounds each lung.Under normal conditions, pleural fluid is secreted by the parietal pleural capillaries at a rate of 0.6 millilitre per kilogram weight per hour, and is cleared by lymphatic absorption leaving behind only 5–15 millilitres of fluid, which helps to maintain a functional ...
The sinus tarsi located in the hindfoot, it is contained by the calcaneus, talus, talocalcaneonavicular joint, and the bottom of the subtalar joint. [1] There are five ligamentous structures present inside it: the intermediate, medial, and lateral roots of the inferior extensor retinaculum; the cervical ligament, and the interosseous talocalcaneal ligament.
The pleural cavity, or pleural space (or sometimes intrapleural space), is the potential space between the pleurae of the pleural sac that surrounds each lung. A small amount of serous pleural fluid is maintained in the pleural cavity to enable lubrication between the membranes , and also to create a pressure gradient .
The pleurae (sg.: pleura) [1] are the two flattened closed sacs filled with pleural fluid, each ensheathing each lung and lining their surrounding tissues, locally appearing as two opposing layers of serous membrane separating the lungs from the mediastinum, the inside surfaces of the surrounding chest walls and the diaphragm.
the calcaneal region encompassing the heel, the plantar region encompassing the sole of the foot. Some regions are combined into larger regions. These include the trunk, which is a combination of the thoracic, mammary, abdominal, navel, and coxal regions. The cephalic region is a combination of all of the head regions.
Pleurisy Pleural linings and space (marked in blue) The pleural space can be invaded by fluid, air, and particles from other parts of the body, which fairly complicates diagnosis. [12] [13] Viral infection (coxsackie B virus, HRSV, CMV, adenovirus, EBV, parainfluenza, influenza, COVID-19) is the most common cause of pleurisy.
In anatomy, a potential space is a space between two adjacent structures that are normally pressed together (directly apposed). Many anatomic spaces are potential spaces, which means that they are potential rather than realized (with their realization being dynamic according to physiologic or pathophysiologic events).
