Scanning electron micrographs illustrating the apical surface appearance of OE in suckling (A1 and A2) and adult (B1 and B2) GRCs. Observed on the epithelial surface in each age group are dendrites of ORNs (O), apices of supporting cells (S) and tunnel-like openings (dotted arrows) of Bowman’s gland ducts. A1 and A2: supporting cells and ORNs appear nearly equal in number (per area) and cilia project in a parallel pattern from the ORN dendritic knobs (Dk) in form of a tuft B1 and B2: ORNs predominate the epithelial surface to almost obscure the supporting cell apices and cilia emerge from around the bases of the ORN dendritic knobs in a radial pattern. Scale bar = 5 µm in A1 and B1, 1 µm in A2 and B2

Grasscutters (GRCs) are hystricognath rodents that predominate West African countries where they are captured and bred in captivity as “microlivestock” and for research. Consequently, research priority has, of late, shifted to aspects of GRC biology particularly with regard to morphofunctional aspects of its body systems. The olfactory system plays...

... Gradual changes led to a limited mucus-producing region with ciliated cells and non-ciliated microvilli. They were also observed to bear short cilia of unequal length (Menco and Farbman, 1987; Traves and Nicklas, 1990;Dhillon and Kaur, 2020;Davies et al., 2020;Kavoi and Ochieng, 2023). The mucosa was longitudinally oriented caudal to this transition zone, and longitudinal short and successive folds in the form of thick cilia were found. ...
Present study was conducted to determine the changes in the surface structure of the upper respiratory tract of Siirt‐coloured mohair goats by the silicone plastination method. Accordingly, the heads of 10 Siirt‐coloured mohair goats procured from slaughterhouses were divided into two halves. Half of each head was plastinated. After macro‐comparisons were made, the deformations of silicone plastination on the surface were examined by comparing the scanning electron microscope (SEM) findings of both upper respiratory tract tissue samples collected from plastinates and fresh material. When the data from scanning electron microscopy were analysed, cilia, cobblestone patterns, goblet cells and gland ducts on the epithelial surface were identified in areas on the upper respiratory tract. The SEM images of the plastinated tissues showed that the surface structures were degenerated due to the deformation of the surface epithelium. The plastination technique damaged the structures on the surface epithelium. Since the plastination technique and scanning electron microscopy have been studied together for the first time, we believe this would contribute to the scientific literature.
