“…The mucous glands at the laryngeal mound called cricoarytenoid salivary glands (King and Mclelland, 1984;Liman et al, 2001 andMohamed, 2004) while, Homberger and Meyers (1989) named these glands as laryngeal glands. As reported by McCallion and Aitken, (1953) in the fowl, the laryngeal glands of turkey were located within the lamina propria and their ducts penetrated the mucosa to open into the pharyngeal cavity. Each gland was formed from a varying number of units, each unit comprising many tubules which open into a common cavity and possessing a common duct.…”

Ten turkey birds were used to study the morphological features of the laryngeal mound grossly, histologically and by scanning electron microscopy. The laryngeal mound appeared to consist of two adjoining, raised; quadrilateral mucosal plates located in the floor of the pharynx. It divided into two parts by laryngeal inlet which was V-shaped. The length of the mound and its inlet measured about 20.45 mm and 13.6 mm respectively. By SEM, the dorsal surface of the laryngeal mound appeared scaly and carried few small conical papillae at its caudal part. At the caudal end of mound, the laryngeal papillae arranged into two rows of the papillae; each row included 20 -24 conical papillae. The rostral row consisted of long spinous conical papillae which carried numerous fine elongated papillae toward their bases and displayed two large gaint papillae on the midline. The caudal row had short conical papillae, their bases were surrounded by numerous thin thron-like papillae. Microscopically, the laryngeal mound covered with stratified squamous epithelium and gradually transformed to pseudostratified ciliated columnar epithelium (respiratory epithelium) at the laryngeal inlet. The cricoarytenoid salivary glands were presented in the lamina propria of the lateral part of the laryngeal mound. Their ducts penetrated the mucosa to open into the pharyngeal cavity. Each gland was formed from a varying number of units, each unit comprising many tubules, opening into a common cavity and possessing a common duct. The glandular tubules lined by mucous secreting cells showing strong PAS positive reaction.

“…This in agreement with our present studies indicated that some muscle fibers inserted between lobular capsules of the preglottal gland and lymphoid tissues are present between septa also in older ages. However, (Mccallion & Aitken, 1953) do not find any muscle fibers or lymphoid tissues within the capsule.…”

To understand the development of the mucous preglottal salivary gland in Coturnix japonica (Japanese quail), morphological and histochemical studies were performed on 20 healthy Japanese quail embryos (aging from 10 th to 17 th incubation days) and 25 healthy quail chicks (aging from 0 th to 60 th days). The primordia of preglottal salivary gland were observed as an epithelial bud at the early embryonic stage, which then elongated and differentiated into secretory units by the end of this stage. In Japanese quails, the preglottal salivary gland was a mucous polystomatic tubuloalveolar unpaired gland composed of two lateral portions and a middle one embedded into the submucosa of the lingual root. The gland openings accompanied taste pore (8.17 μm) of taste buds associated salivary glands type; some skeletal muscle fibers embedded among secretory lobules extended from muscle cricohyoideus at 14 th day-old quail chick. Also, both herbts corpuscles and secretory motor plexus could be detected among secretory lobules. Based on our investigations, the development of the preglottal salivary gland could clearly be distinguished in the embryonic stage into pre bud and bud stages at 10 th day old, cord and branching stages ended by cavitation at 11 th day old, canalization stage at 13 th day old, lobulation and secretory stages by the 17 th day old. This mucous secretion showed different histochemical reactions ended with highly alcinophilic mucous indicated highly sialomucin (acidic) content. Myoepithelial cells could be demonstrated at a 17-day old quail embryo and thereafter surrounded the secretory endpieces of the preglottal salivary gland.

Evidence for amylase in avian salivary glands

Four glands of the house sparrow, chicken and turkey were examined histologically and for their content of amylase. These were the external and intermediate mandibular glands, the maxillary gland and glandula anguli oris of the sparrow and the anterior and posterior mandibular, maxillary and anguli oris glands of the chicken and turkey. Amylase was determined by a starch substrate slide method and by biochemical assay. General morphology and mucopolysaccharide staining are described.All four glands of the sparrow demonstrated significant amylolytic activity by the assay. In the external mandibular and anguli oris glands this activity could be traced to mucous and seromucous cells of origin by means of the starch substrate slide procedure. None of the glands of the chicken or turkey displayed significant amylolytic activity.
