The Scrotum

Digital Storytelling

The scrotum protects the testicles from temperature changes. In order to insure normal sperm production, the scrotum keeps the testes at a temperature slightly cooler than the rest of the body by contracting or expanding. The cremaster muscle contracts when the scrotum is exposed to cold temperatures, pulling the scrotum closer to the body for warmth. When exposed to heat, the cremaster muscle relaxes, enabling the scrotum hang lower and further away from the body. This allows the scrotum to cool.

The scrotum is the one that houses the testes and provides structural support. It is a septum, a specialized connective tissue which is responsible for the internal division which leads to the two specific compartments that contain the testes. It is the scrotum alongside the penis that is firmly attached to the urogenital triangle. The anus is comprised within the posterior section of this triangle.

Context

The Scrotum

Function

It is through a layer of smooth muscle tissue known as dartos which is positioned underneath the scrotum’s skin. The spermatic cord creates the base for a small amount of the bands of skeletal muscle found within the scrotum. This helps to create the spermatic cord, a fascia tube which encompasses the testicular nerves, vessels and ductus deferens. Different temperatures may affect the scrotum as a whole and may cause them to contract closer to the body to feel more body heat.

Facts

The compartments are designed lengthwise and keep their separation through a fibrous scrotal septum. It is this internal segregation which helps protect the testes from infection or damage from the other one. As an added protection against harm, the left testes hangs lower than the right to avoid compression at the moment of impact. The surface of the testes shows evidence of the scrotal septum along with the appearance of a longitudinal line which runs front to back around the whole testes, except for the part which attaches to the body. This is known as the perineal raphe.

The scrotum needs much blood and requires much attention from nerve activity. The internal iliac artery is the one in charge of quenching the scrotum’s need for blood. Along with the internal iliac artery is the femoral artery which also aids in serving the scrotum’s need for blood. The nerves around the scrotum are sensor nerves which include the posterior coetenous nerves which lead to the thigh, ilioinguinuinal nerves and the pudental nerves.
