Germinal Epithelium (other)

	Germinal Epithelium (other) Germinal epithelium can refer to: * Germinal epithelium (female), a layer of cells covering the ovary * Germinal epithelium (male), a layer of cells covering the testicle * Germ layer, primary tissue layer formed during embryogenesis in animals See also * Germinal (other) * Epithelium Epithelium or epithelial tissue is a thin, continuous, protective layer of cells with little extracellular matrix.

	Germinal Epithelium (female) The ovarian surface epithelium, also called the germinal epithelium of Waldeyer, or coelomic epithelium, is a layer of simple squamous-to- cuboidal epithelial cells covering the ovary. The term ''germinal epithelium'' is a misnomer as it does not give rise to primary follicles. Composition These cells are derived from the mesoderm during embryonic development and are closely related to the mesothelium of the peritoneum. The germinal epithelium gives the ovary a dull gray color as compared with the shining smoothness of the peritoneum; and the transition between the mesothelium The mesothelium is a membrane composed of simple squamous epithelium, simple squamous epithelial cells of mesodermal origin, which forms the lining of several body cavities: the pleura (pleural cavity around the lungs), peritoneum (abdominopelvic ... of the peritoneum and the cuboidal cells which cover the ovary is usually marked by a line around the anterior border of the ovary.

	Germinal Epithelium (male) The germinal epithelium is the epithelial layer of the seminiferous tubules of the testicles. It is also known as the wall of the seminiferous tubules. The cells in the epithelium are connected via tight junctions. There are two types of cells in the germinal epithelium. The large Sertoli cells (not dividing) function as supportive cells to the developing sperm. The second cell type is the cells belonging to the spermatogenic cell lineage. These eventually develop into sperm cells (spermatozoon A spermatozoon (; also spelled spermatozoön; : spermatozoa; ) is a motile sperm cell (biology), cell produced by male animals relying on internal fertilization. A spermatozoon is a moving form of the ploidy, haploid cell (biology), cell that is ...). Typically, the spermatogenic cells will make four to eight layers in the germinal epithelium.Junqueira's Basic Histology: Text and Atlas, Thirteenth Edition References External links * - "Male Reproductive System: testis, germinal ep ...

	Germ Layer A germ layer is a primary layer of cell (biology), cells that forms during embryonic development. The three germ layers in vertebrates are particularly pronounced; however, all eumetazoans (animals that are sister taxa to the sponges) produce two or three primary germ layers. Some animals, like cnidarians, produce two germ layers (the ectoderm and endoderm) making them diploblastic. Other animals such as bilaterians produce a third layer (the mesoderm) between these two layers, making them triploblastic. Germ layers eventually give rise to all of an animal's Tissue (biology), tissues and organ (anatomy), organs through the process of organogenesis. History Caspar Friedrich Wolff observed organization of the early embryo in leaf-like layers. In 1817, Heinz Christian Pander discovered three primordial germ layers while studying chick embryos. Between 1850 and 1855, Robert Remak had further refined the germ cell layer (''Keimblatt'') concept, stating that the external, internal ...
