In males the reproductive system contains a series of chambers or sacs along the course of the vas deferens, which produce long tubes (spermatophores) to contain the spermatozoa.
At day 32 preP the heart was already structured in four chambers, the pericardial sac could be distinguished, the stomach was filled with fluid and the ultrasonographic difference between the lung and the liver, the anatomical structure of the diaphragm, was detectable.
Examples include enlarged heart primordium and abnormally enlarged ventricular chambers, detached pericardial sac, small forebrain, flat telencephalic vesicle, failure in neural tube closure, and small and irregularly shaped eyes.
When Gala and Short arrived at the breakdown pile, it was just the back end of a small sealed chamber — another cul-de-sac.
Tumour-induced angiogenesis is usually performed by the dorsal air sac-chamber assay or the chick choriallantoic membrane assay (CAM assay).
In younger teeth of SAC a common pulp chamber was clearly visible.
Further neuropathologic examination occurs after fixation of the thoracic, lumbar and sacral spine within the dural sac in a dedicated chamber.
The number of blood vessels within the chamber in the area of the air sac fascia was counted and quantified.
The number of blood vessels within the chamber in the area of the air sac fascia was counted, and their lengths were measured.
Even though endovascular aneurysm repair (EVAR) creates a closed chamber except for patent branches, the intra-sac pressure is never zero.
