Reproductive system
Male Reproductive System
| Question | Answer |
|---|---|
| List the external organs of the male reproductive system | 1. Penis 2. Scrotum |
| List the internal organs of the male reproductive system | 1. Testes 2. Epididymis 3. Ductus deferens 4. Seminal glands 5. Ejaculatory ducts 6. Prostate glands 7. Bulbourethral gland |
| State the location of the scrotum | Hangs from root of penis |
| Describe the external structure of the scrotum | Separated into lateral portions by median ridge called raphe Consists of loose skin and underlying subcutaneous layer Dartos muscle found in subcutaneous layer controls wrinkling of skin outside scrotum |
| Describe the internal structure of the scrotum | Divided into 2 sacs by scrotal septum each containing a testis Each testis is associated with cremaster muscle which move testes closer to the body |
| Describe the structure of the scrotal septum | Made up of subcutaneous layer and Dartos muscle Composed of smooth muscle fiber bundles |
| State the 2 functions of the scrotum | 1. Protects and supports testes 2. Location regulates temperature of testes (normal sperm production takes place at temperature lower than body temperature) |
| Describe the structure of the testes/testicles | Paired oval glands in scrotum, whitish, approximately 4cm x 2.5cm, covered by 2 tissue layers called tunicas |
| Describe the 2 layers that cover the testes | 1. Tunica vaginalis-thin external serous sac 2. Tunica albuginea-tough fibrous middle membrane -directly encapsule teste, extend inwards dividing testes into series of lobules each containing seminiferous tubules |
| State the main function of seminiferous tubules | Where spermatogenesis takes place |
| State the 2 types of cells found in seminiferous tubules | 1. Sperm forming/ spermatogenic cells: produce sperms 2. Sertoli cells: embedded among spermatogenic cells have nutritive and supportive functions |
| State the functions of sertoli cells | 1. Blood testis barrier 2. Phagocytosis of excess spermatid cytoplasm 3. Release sperms into tubules 4. Release testicular fluid which aid in sperm movement and contain protein for sperm nourishment 5. Produce hormone inhibin |
| State the function of hormone inhibin released by sertoli cells | Regulates effects of testosterone |
