Salivary glands cluster around oesophagus along region of valve of Leiblein and ventral ganglia of nerve ring, attached to lateral surface of anterior oesophagus just anterior to valve of Leiblein (Figs 29, 30: sg); their ducts very narrow, except for short proximal region that runs completely attached to anterior oesophagus wall and, more anteriorly, inside dorsal folds of buccal cavity (Fig.
The infection level on different parts of fish was variable such as: gills 17.93%, buccal cavity 10.72%, eyes 10.24%, operculum 12.10%, head
At metamorphosis, the larval mouth and distal foregut are destroyed and the buccal cavity punches out a new mouth opening at the apex of the developing proboscis (Page, 2000, 2005).
The buccal cavity of Strongyloides stercordlis larvae is short, being one-third to one-half the width of the head (Figure 3) while the buccal cavity of hookworm larvae is slightly longer than the width of the head.
In speech and singing, the supraglottal cavities (i.e., the pharyngeal cavity, the buccal cavity, and in some cases, the nasal and labial cavities) in which the laryngeal sound resonates.
The epithelium of buccal cavity consists of 3 cell types, the tall granulated columnar cells bearing microvilli; which appear as a "brush border" under the light microscope, the nongranulated cells, and the mucus cells having a "goblet" appearance; which are widely scattered in the epithelium (Fig.
The copepod was inside the fish buccal cavity, in the right part of the inferior jaw (intercanine dental space, strongly anchored to the gum).
Most patients with cicatricial pemphigoid manifest oral involvement (desquamative gingivitis), which can progress to the development of a residual scar in the buccal cavity (figure 1).
Specifically, the hypotheses are that a) vertebrate herbivores will express steroid hormone receptors in the buccal cavity and/or the vomeronasal organ; b) absolute sex steroid concentrations will be lower in carnivores than in herbivores; and e) herbivore steroid receptors should be more diverse in their binding affinities than carnivore lineages.
In the larvae of Drosophila melanogaster, the foregut consists of the buccal cavity (atrium), pharynx, esophagus and proventriculus.
These larvae have a short buccal cavity, very different from the long buccal cavity of the rhabditiform larvae of the hookworm (see Figure 6).
