Seminiferous Epithelium
|
D012670 |
[The epithelium lining the seminiferous tubules composed of primary male germ cells (SPERMATOGONIA) and supporting SERTOLI CELLS. As SPERMATOGENESIS proceeds, the developing germ cells migrate toward the lumen. The adluminal compartment, the inner two thirds of the tubules, contains SPERMATOCYTES and the more advanced germ cells.

Seminiferous Tubules
|
D012671 |
[The convoluted tubules in the TESTIS where sperm are produced (SPERMATOGENESIS) and conveyed to the RETE TESTIS. Spermatogenic tubules are composed of developing germ cells and the supporting SERTOLI CELLS.

Seminoma
|
D018239 |
[A radiosensitive, malignant neoplasm of the testis, thought to be derived from primordial germ cells of the sexually undifferentiated embryonic gonad. There are three variants: classical (typical), the most common type; anaplastic; and spermatocytic. The classical seminoma is composed of fairly well differentiated sheets or cords of uniform polygonal or round cells (seminoma cells), each cell having abundant clear cytoplasm, distinct cell membranes, a centrally placed round nucleus, and one or more nucleoli. In the female, a grossly and histologically identical neoplasm, known as dysgerminoma, occurs. (Dorland, 27th ed)

Senna Plant
|
D029846 |
[A plant genus of the family FABACEAE. SENNA EXTRACT is obtained from members of this genus. Members contain ANTHRAQUINONES and have been an ingredient in laxatives (CATHARTICS). Many species of the CASSIA genus have been reclassified into this genus. This bush should not be confused with the Cassia tree (CINNAMOMUM).
