What is the function of the theca?
The theca is one half of the outer silica sheath (frustule) that surrounds diatoms. The two thecae are slightly asymmetrical, one is a bit larger, so that the two overlap a bit in the middle, allowing for expansion along the midline. Upon divison, the two halves separate, and are regenerated in the daughter cells.
What are the treatments for encroachment of anterior theca?
Treatment will depend upon the degree of encroachment. In my experience mild anterior thecal compression (diagnosed by MR scanning) can be associated with acute onset of severe low back pain which may be midline or paravertebral and is frequently associated with a reduced straight leg raise on examination. This sign is generally recognised by clinicians as being associated with more frequent nerve root compression and consequent sciatica which is typically absent in these cases. I find patients with this syndrome respond well to simple rest, modified activities and whatever pain medication they can tolerate together with a thorough explanation of the pain mechanism. Most recover well in a few weeks. However, the problem may well be a precursor of a further disc prolapse and so advice to avoid activities which compress the spine excessively would seem sensible. Perhaps the use of a 'backswing' traction device might be useful for some sufferers.Bill Kusiar, Chiropractor.

How is estrogen formed?
estrogen is formed by the granulosa cells of the follicle. Theca interna cells contain leutinizing hormone receptors that convert LH into testosterone. Granulosa cells contain testosterone receptors that convert testosterone to estrogen. These are the basic steps for the production of estrogen.
What surrounds the eggs before they are released from the ovary?
The following surround the eggs before they are released from the ovary:granulosa cells (cumulus oophorus)the antrum (filled with fluid secreted by the granulosa cells)and the theca interna and externaWhen the egg is released the theca interna and the glanulosa cells become the corpus luteum (which becomes the corpus albicans = scar tissue, if the egg is not fertilized).If the egg is fertilized the corpus luteum persists until the developing fetus takes over the required endocrine requirements (ie HCG secretion)
What is the medical terminology combining form meaning sheath?
Theca- is the medical terminology combining form meaning sheath. For instance, the spinal cord has a theca, and intrathecal injections can be made within it.

What is the difference between spermatogenesis and oogenesis?
Spermatogenesis takes place in the testes of males, oogenesis takes place in the ovary of the females.Spermatogenesis produces small, motile spermatozoa whereas in oogenesis the ovum is spherical, not motile and is much larger with more food reserves and cytoplasm.Spermatogenesis involves a metamorphosis stage called spermiogenesis, in oogenesis there is no metamorphosis stage.In spermatogenesis, 4 gametes are produced from each meiotic division, whereas in oogenesis there is only 1 gamete produced from each division as the unequal cytokinesis leads to the formation of polar bodies.Spermatogenesis occurs in males (human males) continuously from puberty to death whereas oogenesis starts in females in the fetal period. It takes 70 days for sperm to be produced in males.In oogenesis, the development of the oocyte is arrested at prophase I of meiosis until puberty, and then stops at metaphase II of meiosis until fertilization, where the meiotic division is finally completed. In males meiosis occurs continuouslyThe hormones in the 2 processes have different effects - in oogenesis, FSH is responsible for the choice of the primary oocyte and causes the cells of the membrana granulosa to proliferate to form the theca interna which secretes oestrogen, and the theca externa. LH in females stimulates ovulation and the maturation of the Graafian follicle. In males, on the other hand, FSH increases the activity of the Sertoli cells which are involved in spermiogenesis (the metamorphosis stage of spermatogenesis). LH in males stimulates the Leydig cells to secrete testosterone.
What gland produces the egg cells and and hormones?
The hypothalamus in the brain releases Gonadotropin-Releasing Hormone to the pituitary gland, located in your brain behind the eyes. The pituitary gland releases Follicle-Stimulating Hormone (FSH) and Luteinizing Hormone (LH), which go to the ovaries. FSH stimulates the selection of an egg from the ovary, and a surge of LH release stimulates the release of the egg for fertilzation. In the ovary, Theca cells release Testosterone which travels to nearby Granulosa cells which convert the testosterone to estrogen. Theca cells also make progesterone, which is necessary for growing the endometrium, which is what bleeds during the menstrual cycle.
How do we prove we have a relic?
Is the relic enclosed in a theca (locket)? Does it have a wax seal on the back? Does it have a document of authenticity signed by a Church aithority? Which saint is the relic from? Do you have pictures of the relic, seal and document that could be examined by someone who is an expert on relics?

How do you treat Big posterior disc bulging is seen by C5-C6 slightly more on the left side with marked indentation on the ventral theca with narrowing of the left nerve canal?
The disk may have to be excised and the vertebrae fused. The narrowing canal should be reopened by removing some bone to make it wider.
