Study Notes
Seminiferous Tubules
- Sertoli cells are interspersed with germ cells in the seminiferous tubules.
- Sertoli cells provide support and nutrition to developing sperm cells, and they also produce androgen-binding protein (ABP).
- Sertoli cells are located closest to the basement membrane in the seminiferous tubules.
Testes Structure
- The testes are encased in a thick capsule of dense fibroelastic connective tissue called the tunica albuginea.
Cells in Seminiferous Tubules
- Leydig cells are responsible for the production of testosterone in the seminiferous tubules.
- Germ cells are responsible for the production of spermatozoa in the seminiferous tubules.
- Sertoli cells are not responsible for the production of spermatozoa, but they support and nourish the developing sperm cells.
- Macrophages are not found in the germinal epithelium of the seminiferous tubule.
Epididymis
- The function of the epididymis is to store and mature spermatozoa.
Accessory Glands
- The seminal vesicles produce fluids that make up semen.
- The prostate gland produces fluids that make up semen, and its main function is to secrete fluids that nourish and transport sperm.
- The correct statement about the prostate is that it is both an exocrine and endocrine gland.
Penis
- The main function of the penis is to deliver urine and semen out of the body.
- The penile urethra is shared by both the urinary and reproductive systems.
- The correct statement about the penile urethra is that it is the final part of the urethra.
Test your knowledge of the histology of seminiferous tubules, Leydig cells, and Sertoli cells with this quiz. Learn about the functions and characteristics of these important components of the male reproductive system.
