Examples of theca

The other first-order branch apparently does not divide until several thecae have formed.
Second, the priority of theca versus holdfast decay is unclear.
Perinuclear theca during spermatozoa maturation leading to fertilization.
Post-lumbar-puncture headache is an example precipitated by leakage from the punctured lumbar theca.
Only a few theca cells were still attached to the basement membrane.
Note the smooth and rough endoplasmic reticulum and gap junctions between theca-interna cells.
The first two autothecae on each stipe are isolate and strongly down-curved, distal thecae less so.
The first-order branches are horizontal to declined and have between 8 and 24 thecae.
The possession of a theca, however, does not appear to have phylogenetic significance at the level of this analysis.
The proximal thecae are very thickened with cortical deposits.
It is still not well understood whether theca cells and serum are required for oocyte growth in vitro.
Distal thecae are less isolate and tend to be inclined at an acute angle to the stipe.
Regulation of ovarian cell growth through the local production of transforming growth factor-alpha by theca cells.
The preantral follicles retrieved by the enzymatic method lost the basement membrane partly or wholly and the theca cells no longer attached to the follicles.
The funicle is horizontal to declined, 2.0 to 5.5 mm long comprising 2 to 6 thecae.
