Flashcards
Scrotum
Scrotum
A sac of skin and superficial fascia that hangs outside the abdominopelvic cavity at the root of the penis.
Why is the scrotum located outside the body ?
Why is the scrotum located outside the body ?
The external positioning of the scrotum keeps the testes cooler than the core body temperature (around 3 degrees Celsius).

Study Notes
Male Reproductive System Overview
- Male and female reproductive systems originate from similar embryonic tissues.
- During fetal development, reproductive organs are initially near the kidneys.
- The organs gradually move to their final positions.
- By the 7th month, they descend into the scrotum via inguinal canals.
Scrotum
- A sac of skin and superficial fascia.
- Located outside the abdominopelvic cavity, at the root of the penis.
- Maintains testes at 3°C lower than core body temperature, crucial for sperm production.
Scrotum Components
- Dartos Muscle: Thin layer of smooth muscle in the dermis. Contractions cause skin wrinkling.
- Tunica Vaginalis: Encloses each testis. A continuation of the peritoneum. Lines the abdominopelvic cavity.
- Tunica Albuginea: Fibrous capsule covering each testis.
