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 does osteodiscal elevation of the anterior theca mean?

Osteodiscal elevation of the anterior theca refers to the lifting or protrusion of bone structures associated with the anterior aspect of the theca, which is the protective covering of the spinal cord and nerve roots. This condition can suggest the presence of a pathological process, such as a disc herniation or other spinal abnormalities, that may impact the surrounding structures. It is typically evaluated through imaging studies, such as MRI, to determine the underlying cause and appropriate treatment options.


What is the shell of dinoflagellate made of?

The shell of dinoflagellates, known as the theca, is primarily composed of cellulose plates, which are often reinforced with organic materials. These plates can vary in shape and size, contributing to the diverse morphology of dinoflagellate species. The theca provides structural support and protection, and its intricate patterns can be used for species identification. Some dinoflagellates also produce a covering of silica or other materials, depending on the species and environmental conditions.


Do target cells of the kidneys respond to LH?

No, target cells of the kidneys do not respond to luteinizing hormone (LH). LH primarily targets the gonads, specifically the Leydig cells in the testes and the theca cells in the ovaries.

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)
