The portion between the sulcus intermedius and the duodenopyloric constriction is termed the pyloric antrum.
The antrum is tubular and sclerotized, with the ductus seminalis attaching at its upperside base.
Specifically, it is an inflammation of the mucosal lining of the mastoid antrum and mastoid air cell system inside the mastoid process.
The cyst may invaginate the antrum, but there should be evidence of a cortical boundary between contents of cyst and internal structure of antrum.
Growth of preantral follicle was assessed by diameter measurement and antrum formation rate and oocyte growth was assessed by diameter measurement and survival ratio.
Alternatively, antrum, rather than theca cells, may be important for oocyte survival and growth by maintaining the intrafollicular microenvironment and sustaining the integrity of the follicles.
They found that the heparin-like compounds are synthesized mainly by the granulosa and theca cells and are released into the follicular antrum, suggesting a process of active secretion.
Reversal of anionisation, however, restores their capacity to freely enter the antrum once again.
