The gular gland of the bat Tadarida brasiliensis is a specialized sebaceous gland located in the skin of the suprasternal region of adult males. It consists of an aggregation of simple branched tubulo‐acinar gland units, the number of which varies seasonally. Each acinus is composed of densely packed sebaceous cells at various stages of differentiation. Acinar basal cells and cells of the epithelium of the ducts can differentiate into sebaceous cells. Two main changes appear in the cytoplasm…

Reproductive biology of the male little mastiff bat, Mormopterus planiceps (Chiroptera:Molossidae), in southeast Australia.
TLDR
Observation of the appearance of spermatozoa in the ductus deferens in August/September suggested that mating could occur during the interval from autumn to spring, and aspects of the male reproductive cycle in M. planiceps that have not heretofore been described in another molossid bat.
Female reproductive patterns in nonhibernating bats.
TLDR
In order to elucidate the normal oestrous cycle and define the structural and functional characteristics of the ovaries of this nonhibernating bat several analytical technique were utilized.
Crystalloids in the excretory ducts of the accessory submandibular gland of the long‐winged bat, Miniopterus magnator
TLDR
It is postulate that the ductular crystalloids in M. magnator might be involved in production of a factor that influences mating behavior, and similar crystalloids connected to smooth endoplasmic reticulum play a role in steroid metabolism.
Histological examinations of facial glands in Saccopteryxbilineata (Chiroptera, Emballonuridae), and their potential use in territorial marking
TLDR
Investigating the facial glands of Saccopteryx bilineata histologically found that both sexes possess a bilateral symmetrically intermandibular gland, and lip glands consisting of modified apocrine sudoriferous cell units with pigmented ducts around the upper and the lower lip are probably involved during territorial marking.
Gular gland of the Indian sheath-tailed bat
The morphology, histology and histochemistry of the gular gland of the Indian sheath-tailed bat, Taphozous longimanus Hardwicke, 1823, are described. A gular gland which is presented only in the male
FREE-TAILED BATS (TADARIDA BRASILIENSIS MEXICANA)
TLDR
The Mexican free-tailed bat is primarily a nonhibernating, migratory, spring-breeding subspecies and function of secondary sex glands are in synchrony with an activation of the male reproductive tract, which lead to insemination of estrogenic, receptive females.
REPRODUCTIVE BIOLOGY OF MALE MEXICAN FREE-TAILED BATS (TADARIDA BRASILIENSIS MEXICANA)
TLDR
Mating behavior of males and function of secondary sex glands are in synchrony with an activation of the male reproductive tract (spermatogenesis), which lead to insemination of estrogenic, receptive females.
A histological examination of the holding sacs and glandular scent organs of some bat species (Emballonuridae, Hipposideridae, Phyllostomidae, Vespertilionidae, and Molossidae)
TLDR
Using histological techniques at the light-microscope level, structure and sexual dimorphism of the wing sacs and integumentary glandular scent organs of 11 species of microchiropteran bats were examined and it was confirmed that they were holding sacs rather than glands.

The differentiating sebaceous cells in three species of galagos have different structural configurations of cytoplasmic membranes, and individual tubules of agranular endoplasmic reticulum are also abundant in the cells.

TLDR
Sebaceous glands are holocrine glands, secreting by extrusion of entire cells; as secretion occurs, new cells are forming at the periphery of the acini.
Poliovirus Crystals within the Endoplasmic Reticulum of Endothelial and Mononuclear Cells in the Monkey Spinal Cord
TLDR
The lumbar motor columns of a cynomolgus monkey that had become tetraplegic after experimental infection with a highly virulent strain of type 3 poliovirus were examined by electron microscopy, suggesting that the endoplasmic reticulum might be much more involved in poliov virus multiplication than has been previously supposed.
Lipid composition and turnover of rough and smooth microsomal membranes in rat liver.
TLDR
The membranes of the rough and the two smooth microsomal subfractions from rat liver have a similar phospholipid composition, but are dissimilar in their neutral lipid content and in the incorporation rate of precursors into membrane lipids.
Androgen Control of Territorial Marking in the Mongolian Gerbil
TLDR
Gerbils mark objects with the secretion of a midventral sebaceous gland, and it is possible that the secretion acts as a pheromone to signal territorial possession.

TLDR
The search for a medium which might offer improvements from the point of view of stability and buffering capacity for Palade's buffered osmic fixative was focused on s-collidine, which has a pK of about 7.4.
