Seminiferous tubule
Seminiferous Tubule
The Seminiferous Tubule (/ˌsɛmɪˈnɪfərəs ˈtjuːbjuːl/) is a structure within the testis that is involved in the production of sperm.
Etymology
The term "seminiferous tubule" is derived from the Latin words "semen" meaning "seed" and "ferre" meaning "to bear". The term "tubule" comes from the Latin "tubulus" meaning "small tube".
Function
The primary function of the seminiferous tubules is to produce spermatozoa, or sperm cells, through a process known as spermatogenesis. This process involves the division and maturation of spermatogonia, which are the germ cells located within the seminiferous tubules.
Structure
The seminiferous tubules are coiled structures that are lined with a layer of cells known as the germinal epithelium. This layer contains the spermatogonia as well as Sertoli cells, which provide support and nourishment to the developing sperm cells.
