  2. Lobules of testis - Wikipedia

    en.wikipedia.org/wiki/Lobules_of_testis

    The lobules are conical in shape, the base being directed toward the circumference of the organ, the apex toward the mediastinum testis. Each lobule is contained in one of the intervals between the fibrous septa which extend between the mediastinum testis and the tunica albuginea , and consists of from one to three, or more, minute convoluted ...

  3. Seminiferous tubule - Wikipedia

    en.wikipedia.org/wiki/Seminiferous_tubule

    There are two types: convoluted and straight, convoluted toward the lateral side, and straight as the tubule comes medially to form ducts that will exit the testis. The seminiferous tubules are formed from the testis cords that develop from the primitive gonadal cords, formed from the gonadal ridge.

  4. Testicle - Wikipedia

    en.wikipedia.org/wiki/Testicle

    The testes are covered by a tough fibrous shell called the tunica albuginea. [5] Under the tunica albuginea, the testes contain very fine-coiled tubes called seminiferous tubules. [5] The tubules are lined with a layer of cells that develop from puberty through old age into sperm cells (also known as spermatozoa or male gametes). [5]

  5. Septa of testis - Wikipedia

    en.wikipedia.org/wiki/Septa_of_testis

    The septa testis are fibrous partitions of the testis dividing the testis into compartments - the lobules of the testis. The septa are formed by extensions of the tunica albuginea - the dense fibrous connective tissue surface covering of the testis - into the substance of the testis. The septa converge towards the mediastinum testis. [1]

  6. Sertoli cell - Wikipedia

    en.wikipedia.org/wiki/Sertoli_cell

    Sertoli cells are a type of sustentacular "nurse" cell found in human testes which contribute to the process of spermatogenesis (the production of sperm) as a structural component of the seminiferous tubules. They are activated by follicle-stimulating hormone (FSH) secreted by the adenohypophysis and express FSH receptor on their membranes.

  7. Tubuli seminiferi recti - Wikipedia

    en.wikipedia.org/wiki/Tubuli_seminiferi_recti

    The tubuli seminiferi recti (also known as the tubuli recti, tubulus rectus, or straight seminiferous tubules) are structures in the testicle connecting the convoluted region of the seminiferous tubules to the rete testis, although the tubuli recti have a different appearance distinguishing them from these two structures.

  8. 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.

  9. Vas deferens - Wikipedia

    en.wikipedia.org/wiki/Vas_deferens

    The vas deferens (pl.: vasa deferentia), ductus deferens (pl.: ductūs deferentes), or sperm duct is part of the male reproductive system of many vertebrates. In mammals, spermatozoa are produced in the seminiferous tubules and flow into the epididymal duct. The end of the epididymis is connected to the vas deferens.
