The salt enables the lamps to give out a very intense white light. A dysprosium oxide-nickel cermet (a composite material of ceramic and metal) is used in nuclear reactor control rods. It readily absorbs neutrons, and does not swell or contract when bombarded with neutrons for long periods.
Summary. Seminal vesicles are glands that produce 60% of the fluid found in semen. Seminal fluid from these glands contains sugar, prostaglandins, metals, and other components necessary to support the activity of sperm.eminal vesicles release up to 60% of the fluid found in semen. The other 40% is produced by the prostate and bulbourethral glands. The fluid produced by seminal vesicles will contain several key components: â¢ Fructose, which is a sugar that is produced to provide energy for swimming sperm cells.
The pseudostratifiedcolumnar epithelium in seminal vesicles is surrounded by thick fibromuscular tissue. The vesicle epithelium is composed of columnar and basal epithelial cells. The columnar epithelium typically contains large amounts of lipofuscin pigment.An unusual feature of normal epithelial cells is the feature of cellular atypia.However, atypical cells are often encountered in the seminal vesicle epithelium, where epithelial cells with large atypical nuclei often are present.he seminal vesicles are paired, highly coiled, tubular structures located above the prostate and behind the urinary bladder. The seminal vesicles merge with vas deferens before debouching into the intra-prostatic urethra.
