  2. Seminiferous tubule - Wikipedia

    en.wikipedia.org/wiki/Seminiferous_tubule

    Seminiferous tubule in cross-section (large tubular structure – center of image) with sperm (black, tiny, ovoid bodies furthest from the outer edge of the tubular structure). H&E stain . 1: Testicular septa

  3. Enrico Sertoli - Wikipedia

    en.wikipedia.org/wiki/Enrico_Sertoli

    Sertoli's idealised drawing illustrating a cross section of a seminiferous tubule. (1878) Enrico Sertoli (June 6, 1842, Sondrio – January 28, 1910, Sondrio) was an Italian physiologist, histologist, anatomist, biologic chemist, physician, teacher, and inventor. He is remembered for his discovery regarding the branched cells of seminiferous ...

  4. Leydig cell - Wikipedia

    en.wikipedia.org/wiki/Leydig_cell

    Histological section through testicular parenchyma of a boar. 1 Lumen of convoluted part of the seminiferous tubules, 2 spermatids, 3 spermatocytes, 4 spermatogonia, 5 Sertoli cell, 6 myofibroblasts, 7 Leydig cells, 8 capillaries

  5. Sertoli cell - Wikipedia

    en.wikipedia.org/wiki/Sertoli_cell

    Cross-section of a seminiferous tubule of the testis of a rat (250x) The function of Sertoli cells in the Amniota and Anamniota is the same, but they have slightly different properties when compared to each other. Anamnionts (fish and amphibians) employ cystic spermatogenesis in order to produce sperm cells. [22]

  6. Testicle - Wikipedia

    en.wikipedia.org/wiki/Testicle

    Within the seminiferous tubules, the germ cells develop into spermatogonia, spermatocytes, spermatids and spermatozoa through the process of spermatogenesis. The gametes contain DNA for fertilization of an ovum. [7] Sertoli cells – the true epithelium of the seminiferous epithelium, critical for the support of germ cell development into ...

  7. Spermatidogenesis - Wikipedia

    en.wikipedia.org/wiki/Spermatidogenesis

    Cross section of the epithelium of a seminiferous tubule showing various stages of spermatocyte development Scheme showing analogies in the process of maturation of the ovum and the development of the spermatids (young spermatozoa). Spermatidogenesis is the creation of spermatids from secondary spermatocytes during spermatogenesis.

  8. Blood–testis barrier - Wikipedia

    en.wikipedia.org/wiki/Blood–testis_barrier

    The walls of seminiferous tubules are lined with primitive germ layer cells and by Sertoli cells. [1] The barrier is formed by tight junctions, adherens junctions and gap junctions between the Sertoli cells, which are sustentacular cells (supporting cells) of the seminiferous tubules, and divides the seminiferous tubule into a basal compartment (outer side of the tubule, in contact with blood ...

  9. Seminal tract - Wikipedia

    en.wikipedia.org/wiki/Seminal_tract

    The seminal tract is a part of the male reproductive system and consists of seminiferous tubules (tubuli seminiferi recti, rete testis, efferent ducts), epididymides , Vas deferens and ejaculatory ducts.
