• theca

  theca of follicle ; theca folliculi ; follicular theca WKP
  Definition : The theca folliculi comprise a layer of the ovarian follicles. They appear as the follicles become secondary follicles.
  The theca are divided into two layers, the theca interna and the theca externa.
  Theca cells are a group of endocrine cells in the ovary made up of connective tissue surrounding the follicle. They have many diverse functions, including (...)

• theca externa
  3 March 2021

  WKP
  Definition : The theca externa is the outer layer of the theca folliculi. It is derived from connective tissue, the cells resembling fibroblasts, and contains abundant collagen.
  During ovulation, the surge in luteinizing hormone increases cAMP which increases progesterone and PGF2α production. The PGF2α induces the contraction of the smooth muscle cells of the theca externa, increasing intrafollicular pressure.
  This aids in rupture of the mature oocyte, or immature oocyte at the (...)

• theca interna
  3 March 2021

  WKP
  Definition : Theca lutein cells are also known as small luteal cells.
  Theca interna cells express receptors for luteinizing hormone (LH) to produce androstenedione, which via a few steps, gives the granulosa the precursor for estrogen manufacturing.
  After rupture of the mature ovarian follicle, the theca interna cells differentiate into the theca lutein cells of the corpus luteum. Theca lutein cells secrete androgens and (...)

• thyroid gland tissue in ovary
  29 April 2020

  Etiology
  struma ovarii / ovarian mature teratoma Struma ovarii represents less than 3% of ovarian teratomas. It can be associated with thyroid biology abnormalities, and in exceptionally rare cases it can be malignant.
