Tubuli Seminiferi Recti
The tubuli seminiferi recti are a series of straight tubules that form part of the male reproductive system. They play a crucial role in the transport of spermatozoa from the seminiferous tubules to the rete testis. This article provides a comprehensive overview of the structure, function, and clinical significance of the tubuli seminiferi recti.
Anatomy[edit | edit source]
The tubuli seminiferi recti are located within the testes, which are the primary male reproductive organs. They are the continuation of the seminiferous tubules, which are highly coiled structures where spermatogenesis occurs.
Structure[edit | edit source]
The tubuli seminiferi recti are short, straight ducts that connect the seminiferous tubules to the rete testis. They are lined by a simple cuboidal epithelium, which is distinct from the stratified epithelium of the seminiferous tubules. The transition from the seminiferous tubules to the tubuli seminiferi recti is marked by a narrowing of the lumen and a change in epithelial cell type.
Location[edit | edit source]
The tubuli seminiferi recti are located at the apex of each lobule of the testis. They converge towards the mediastinum testis, where they enter the rete testis.
Function[edit | edit source]
The primary function of the tubuli seminiferi recti is to transport spermatozoa from the seminiferous tubules to the rete testis. This transport is facilitated by the flow of testicular fluid, which is secreted by the Sertoli cells within the seminiferous tubules.
Clinical Significance[edit | edit source]
The tubuli seminiferi recti, while not commonly associated with specific pathologies, can be involved in certain testicular conditions. Obstruction or damage to these tubules can lead to impaired sperm transport and contribute to male infertility.
Pathologies[edit | edit source]
- Obstruction: Blockage of the tubuli seminiferi recti can occur due to congenital abnormalities or acquired conditions such as inflammation or trauma.
- Infections: Infections of the testis, such as orchitis, can affect the tubuli seminiferi recti and disrupt normal sperm transport.
