Cholinergic transmission in vas deferens

open access: yesGeneral Pharmacology: The Vascular System, 1983
Prazosin, haloperidol, propranolol or timolol had no effect on the electrically evoked muscular twitch. Atropine was able to antagonize competitively acetylcholine (pA2 = 9.29 +/- 0.30). The muscular twitch of the Octodon degus vas deferens was only partially abolished by atropine (53.2 +/- 0.72).

Testis and vas deferens morphology of the red-clawed mangrove tree crab (Goniopsis cruentata) (Latreille, 1803)

open access: yesBrazilian Archives of Biology and Technology, 2006
The present study describes the structure of the testes and vas deferens of the red-clawed mangrove tree crab, Goniopsis cruentata. Testes and vas deferens were fixed with cold Bouin's solution and submitted to histological routine examinations.

Ultrastructure of the reproductive system of the black swamp snake (\u3ci\u3eSeminatrix pygaea\u3c/i\u3e). Part III. The sexual segment of the male kidney. [PDF]

open access: yes, 2002
In mature male snakes and lizards, a distal portion of the nephron is hypertrophied in relation to its appearance in females and immature males. This sexual segment of the male kidney apparently provides seminal fluid that is mixed with sperm and ...

The annual cycle of spermatozoa content in the vas deferens and some reproductive parameters in the narrow-clawed crayfish Pontastacus leptodactylus (Eschscholtz, 1823)

open access: yesAquaculture Reports, 2019
Understanding the annual dynamic of gametes in crayfish is useful for successful management of crayfish population. The annual variations in spermatozoa content of vas deferens, gonado-somatic index (GSI), hepatosomatic index (HSI), vas deferens index ...

Physiological and Pharmacological Aspects of the Vas Deferens - an Update

open access: yesFrontiers in Pharmacology, 2013
The vas deferens, a muscular conduit conveying spermatozoa from the epididymis to the urethra, has been used as a model tissue for smooth muscle pharmacological and physiological advancements. Many drugs, notably α-adrenergic antagonists, have effects on
