Another interesting aspect is the occurrence of a transport epithelium in the genital chamber, characterized by conspicuous infoldings
of membranes associated with numerous mitochondria.
The presence of apical membrane infoldings
provides increased surface area for export of proteins to form the cuticular intima of the pharynx.
Vitaceae: Periasamy, 1962b) or result of infoldings
of the complete testa (e.
I propose the following putative synapomorphies for Carvalhomiris: large genital capsule with cephalic, lateral margin strongly emarginate; strong brachypterism in both sexes; fight paramere clubbed, with apical margin serrate; vesica with a single, large, C-shaped spicule, with its base nearly reaching the cephalic end of the aedeagus; lateral infoldings
of the sclerotized tings on the dorsal labiate plate with a posteriad acute process; and dorsal labiate plate with a cuplike depression projecting into the vestibulum.
and secretions within the glands are a clue to the diagnosis at low-power magnification, but a high-power image (Figure 4, D) was not provided in the quiz.
Aggressive digital papillary adenocarcinomas exhibit cystic zones that manifest papillary infoldings
and are lined with benign cuboidal epithelium, more cellular zones of atypical adenomatous hyperplasia, and areas of overt adenocarcinoma (Figure 2, B).
The ductal structures showed an irregular outline with infoldings
of the glands.
