2022
To date, the development of parathyroid gland (PG) identification methods is limited by the lack of animal models in preclinical research. Here, we establish a simple and effective rat model for intraoperative PG imaging and evaluate its effectiveness by using iron oxide nanoparticles as a novel PG contrast agent.

We developed a method to successfully remove, process, section, and stain, for histopathological evaluation, mammary tissue that had originally been fixed on slides as whole mounts. This method may promote the collection and evaluation of mammary gland whole mounts in reproductive and developmental test guideline studies.

FAQs
The duct provides the route by which materials move from the glandular lumen to an epithelial surface or body cavity. Because the duct remains unbranched, it creates a direct connection between the secretory portion and the destination of the secretion. This arrangement helps relate gland structure to the delivery of mucus, enzymes, or sweat.
Simple Glands may contain tubular, coiled tubular, or acinar secretory portions. These shapes represent different structural arrangements of the cells that produce glandular secretions, while the duct continues to conduct the products outward. Recognizing these forms helps biology students distinguish gland organization when examining epithelial tissues or comparing examples.
Epithelial cells in the secretory portion synthesize the materials released by the gland, including mucus, enzymes, or sweat. Their activity gives the gland its functional output, while the lumen provides the space into which those products are released before transport. This links cellular production with the gland’s broader physiological role.
Their secretions can lubricate surfaces, support digestion, protect epithelial regions, or contribute to temperature regulation. The specific outcome depends on the material produced and where the duct delivers it. Consequently, gland structure should be interpreted together with secretion type and destination rather than as an isolated epithelial feature.
Begin by locating the secretory portion, then identify its lumen and follow the continuous duct toward the epithelial surface or body cavity. Next, note whether the secretory region is tubular, coiled tubular, or acinar and consider which product it releases. This sequence connects microscopic organization with glandular function.
Intestinal glands, gastric glands, and sweat glands illustrate how this organization appears in different biological settings. Together, these examples connect gland structure with digestion and temperature regulation, while the broader group also supports lubrication and protection. Comparing them shows how epithelial secretion serves varied local and physiological needs.
