THE EROGENOUS ZONES - NERVE SUPPLY.

THE EROGENOUS ZONES:
THEIR NERVE SUPPLY AND SIGNIFICANCE.

 

PREPUCE:

The mucocutaneous end-orgas extend from the distal margin of the prepuce to the site at which hairy skin begins, where they diminish and disappear.

Because of the thin dermis and minimal subcutaneous tissue in the prepuce, the nerve networks are closely set.

The number of Vater-Pacini corpuscles in tissue from the adult appears to be decreased from that in tissue from the newborn.     

 

This decrease is apparently relative, however, and seems to be due to expansion of the organ rather than to diminution of the absolute number of corpuscles present.

 

This observation indicates that Vater-Pacini corpuscles do not form after birth.

 

In contrast, the mucocutaneous end-organs are formed in the prepuce after birth.

 

One primitive ending was found in the prepuces of 30 newborn infants, while many well organized end-organs are present in each sample from the prepuce of the adult.
