What's the difference between epididymis and paratesticle?
Epididymis
Definition:
(n.) An oblong vermiform mass on the dorsal side of the testicle, composed of numerous convolutions of the excretory duct of that organ.
Example Sentences:
(1) The most actively proliferating region of the excurrent duct system is zone 3 of the epididymis, whereas the least active region is the ductuli efferentes.
(2) The epididymis appeared distended but without any visible sperms.
(3) The sulfhydryl group content of rat epididymal spermatozoa was similar from one cell to another, suggesting little sperm reabsorption in the epididymis.
(4) Corresponding hydrolysis of the water phase from incubation of epididymis from intact rats, demonstrated a marked quantitative difference.
(5) The ureter was connected to the epididymis of the testicle.
(6) Specific high affinity saturable binding proteins for oestradiol-17beta have been demonstrated in the cytoplasm of liver, adrenal, pituitary, prostate, epididymis and testis interstitial tissue of the rat.
(7) As for possible causes of reduced Leydig cell activity it was investigated whether the testis was (1) hypoplastic; (2) abnormally fused with the epididymis; (3) located in the abdomen; (4) or UT was associated with hypospadias.
(8) The acrosin inhibitors are localized in the mucosa cells of the cauda epididymis, the vas deferens, the seminal vesicles, the urethra and distinct glandular units of the prostate.
(9) An investigation of the tissue distribution of CMB-2 showed that the puberty, CMB-2 is secreted into the rete testis and accumulates in the epididymis in high concentration.
(10) The tail(s) of the epididymis was the most frequent site of lesion development in the mature rams (86.4%).
(11) Intratesticular testosterone and 5 alpha DHT concentrations were determined, and the testis and epididymis were evaluated for histological changes.
(12) These binding sites, localized in the circumference of the epididymal tubule and most concentrated within the proximal cauda, are present throughout the caput, corpus, and remaining cauda epididymis.
(13) Within the epididymis, regions closest to the testis develop soluble ACE activity about 1 week before those nearest to the vas deferens.
(14) The 8.2S form of the AR is also present in all three segments of the immature epididymis, with the highest concentration occurring in the caput.
(15) The influence of androgens on the male accessory glands of the rat was assessed in terms of changes in weight and of the specific activity of the mitochondrial enzymes, succinate dehydrogenase, glycerolphosphate dehydrogenase and pyruvate carboxylase, in the epididymis.
(16) The concentration of FN in soluble tissue extracts of epididymis was determined by enzyme-linked immunosorbent assay (ELISA).
(17) We report the use of a sensitive and specific enyzme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR) to study the expression of protein D, a major androgen-regulated sperm-binding glycoprotein at the protein and mRNA level in different anatomical regions of the rat epididymis.
(18) The results are discussed in relation to protein secretion in the epididymis and to the role of antagglutinin in the gamete-interaction process.
(19) The primary amino acid sequence of 18.5 kDa androgen-dependent secretory proteins of the rat epididymis has been compared with protein data-base sequences.
(20) More ABP was endocytosed in proximal regions of the epididymis than any other protein studied.
