Distal Excurrent Ducts And Penile Morphology Of The Urogenital System In The Mississippi Mud Turtle, Kinosternon Subrubrum Hippocrepis (Chelonia:Kinosternidae), Stanley E. Trauth, Michael V. Plummer
Distal Excurrent Ducts And Penile Morphology Of The Urogenital System In The Mississippi Mud Turtle, Kinosternon Subrubrum Hippocrepis (Chelonia:Kinosternidae), Stanley E. Trauth, Michael V. Plummer
Journal of the Arkansas Academy of Science
We examined the distal excurrent ductal morphology and penile anatomy of the urogenital system in the Mississippi Mud Turtle, Kinosternon subrubrum hippocrepis, from a small sample of individuals collected in Arkansas in order to provide additional information regarding turtle urogenital anatomy. Specifically, we focused on the basic anatomy and histology of distal excurrent ducts (ductus deferens and ureter), associated structures (urogenital papillae), and penile histology in this kinosternid turtle. In addition, we provide an overview of the gross urogenital anatomy in this turtle, given that little detailed information exists on this topic in the chelonian literature.
Morphology Of Rathke’S Glands In The Alligator Snapping Turtle, Macrochelys Temminckii (Chelonia: Chelydridae), Stanley E. Trauth
Morphology Of Rathke’S Glands In The Alligator Snapping Turtle, Macrochelys Temminckii (Chelonia: Chelydridae), Stanley E. Trauth
Journal of the Arkansas Academy of Science
I examined the morphology of Rathke’s glands (RG) in the Alligator Snapping Turtle, Macrochelys temminckii, using light microscopy and scanning electron microscopy. This species possesses 4 pairs of RG (i.e., an axillary and three inframarginals) that are embedded beneath marginal bones and are named primarily according to the anatomical location of their orifices. These holocrine-type, exocrine, integumentary glands are anatomically and ultrastructurally similar to one another. Each gland contains a single and highly vascularized secretory lobule, which is bounded by a thick tunic of asymmetrically-arranged striated muscle bundles. Two types of secretory vacuoles were identified within the holocrine cells …
