seminal duct
Học thuậtThân thiện
Definition
Noun: * The efferent duct of the testis in humans: A seminal duct is a specific anatomical structure, a tube, that carries sperm cells (spermatozoa) away from the testis. It is a key component of the male reproductive system's pathway for sperm transport.
Usage
The term "seminal duct" is a precise, scientific term used almost exclusively in biological, medical, and anatomical contexts. It refers to a specific part of the male reproductive anatomy. * The surgeon carefully avoided damaging the seminal duct during the procedure. * A blockage in the seminal duct can be a cause of male infertility.
Advanced Usage
- In detailed anatomical discussion, the seminal duct is often described as part of a larger system. It is specifically the efferent duct, meaning it carries material the testis, distinguishing it from ducts that carry material toward it.
Variants and Related Words
- Vas Deferens (noun): This is a more specific and commonly used term. The vas deferens is the duct that carries sperm from the epididymis (where the seminal ducts empty into) toward the urethra. While related, "seminal duct" and "vas deferens" are not perfect synonyms; the seminal duct is a smaller duct leading the vas deferens.
- Efferent Duct (noun): A general anatomical term for any duct that carries fluid away from an organ or gland. The seminal duct is a type of efferent duct.
- Sperm Duct (noun): A less technical, general term that can sometimes be used interchangeably with "seminal duct" or "vas deferens" in non-specialist language.
