pampiniform
Varicocele refers to the dilatation and tortuosity of the pampiniform plexus (a network of veins that drain the testicle).
The pampiniform plexus is a network of veins located in the spermatic cord of males. It helps regulate the temperature of the testes by acting as a heat exchanger, cooling the arterial blood on its way to the testes. This helps maintain the ideal temperature for sperm production.
In either case there is a bed of veins called the pampiniform plexus which directly drain the organs blood supply. The plexus then drains into discreet veins; from the ovaries, the ovarian veins and from the testes, the testicular veins. These discreet veins connect directly to the inferior vena cava.
The pampiniform plexus
Arteries - distribution arterioles - adjust blood pressure capillaries - exchange gas and nutrients with cells veins - collection and return blood to the heart. Also portal veins - connect two sets of capillary beds (there are 4: intestine to liver, pituitary gland, kidney, pampiniform plexus (embryonic structure))

The two primary nerve plexuses regulating digestive function are the myenteric plexus (Auerbach's plexus) and the submucosal plexus (Meissner's plexus). They are part of the enteric nervous system and play important roles in controlling gastrointestinal motility, secretion, and blood flow.
The phrenic nerve plexus supplies the diaphragm and controls its movement during respiration. Damage to this plexus can lead to impaired breathing and respiratory function.
The Choroid Plexus has a main function of filtering, removing waste, and foreign substances. It is also responsible for removing excess neurotransmitters.

The major plexuses of the spinal cord are the cervical plexus (C1-C5), brachial plexus (C5-T1), lumbar plexus (L1-L4), and sacral plexus (L4-S4). These plexuses are networks of nerves that supply motor and sensory function to various regions of the body.
