What Does The Pampiniform Venous Plexus Do?

Varicocele is the dilatation of the pampiniform plexus of veins, a network of many small veins found in the male spermatic cord. It is the most frequently encountered mass of the spermatic cord.

Where does the spermatic vein drain?

The left spermatic vein drains into the left renal vein at a right angle, and the right spermatic vein drains into the inferior vena cava at an obtuse angle.

What vein drains the testis?

We demonstrated that the venous drainage of the testis is via the pampiniform plexus, which is primarily drained by the testicular and external pudendal veins. The testicular vein–midway between the internal inguinal ring and the lower pole of the kidney–divides into the medial and lateral branch to form a delta.

Where does right testicular vein drain?

What is the function of the pampiniform plexus quizlet?

The pampiniform plexus helps regulate the temperature of the testes by acting as a “heat exchange” mechanism to cool down the blood. The arteries supplying the testes run through the plexus where the blood is cooled from abdominal arterial temperature to testicular temperature.

What are four functions of Sustentacular cells?

What are the four functions of Sustentacular Cells? Provide growth factors to germ cells, promote germ cell development, protect germ cells, and to provide nutrients to germ cells.

Where is sperm stored?

A long tube that is located near each testicle. The epididymis is the tube which moves the sperm from the testicles. Vas deferens. This is a tube in which the sperm is stored and it carries the sperm out of the scrotal sac.

Why varicocele is common on left side?

Varicoceles happen mostly on the left side of the scrotum. This is because a guy’s body is organized so that blood flow on that side of the scrotum is greater, so varicoceles happen more often in the left testicle than the right. Although it’s less common, they can sometimes happen on both sides.

What causes varicocele?

Varicocele Causes

Varicoceles are believed to be caused by defective valves in the veins within the scrotum, just above the testicles. Normally, these valves regulate the flow of blood to and from the testicles. When normal flow doesn’t occur, the blood backs up, causing the veins to dilate (enlarge).

What does the left testicular vein drain into?
