A man’s penis is a lot like a giant, almost impossible to see in full, a new study has found.
The University of Sydney team said they found the man’s body was made up of around 12,000 nerve cells that “flickered” in the right direction when stimulated.
They also found a network of muscles in his back and shoulders were capable of moving, and his genitals were covered in skin cells that were “very flexible and elastic”.
The new findings may help doctors understand how penis cells work.
The study, published in the journal Scientific Reports, used a computer simulation model to simulate a penis with the right wiring.
It showed that the nerve cells in the penis were able to respond to stimulation by sending information to the body via nerve impulses, or signals from the cells.
“These nerve cells, which are very important to the functioning of the penis, are very small and therefore hard to see,” said Dr Andrew Dutton, the lead author.
“When we stimulated them with electrical pulses they would start to flicker, and then they would stop flicking and just start to move, but not in a way that we can see in the simulation.”
The flickers were like the motions of a finger.
We could see the motion and the movement of these nerve cells but we didn’t have to do much of that because the computer simulation did it for us.
“The researchers also discovered that the penis had a special kind of nerve that allowed it to respond “off the cuff” to different types of stimulation.”
This is where we found the most important part of the whole penis is the nerve cell network that is in the tip of the glans,” Dr Dutton said.”
That network is actually very flexible and the nerves in that network respond to different kinds of stimulation and that is why it is so important to be able to see the movement, the flicker of these nerves, the movement when they are stimulated off the cuff.
“So the next step is to figure out how that network responds to different stimulation types.”
Researchers said the findings showed that penis cells were “a powerful tool” for doctors.
“By understanding the precise workings of these cells, we can learn more about how these cells work and where they are in the body, how they respond to pressure and other things,” Dr Chris Ketchum, from the University of Western Sydney, said.
The penis is an “important organ” for humans, and it has long been a topic of research.
“Many penis problems and disorders can be caused by a lack of a normal penis,” Dr Ketchums co-author Professor Stephen White said.
The study also found that the human penis has a “unique network of nerve cells”, and that the brain was responsible for controlling that network.
The human penis is not the only body part with nerves.
The Australian National University also discovered the existence of nerves in a “small part” of the human body, called the perineum, which is where the nerves come from.
That study also suggested that the nerves are not located in the head and neck.
But there is a growing body of research that suggests there are nerves in the brain as well.
“Our findings demonstrate that the perinesum is a unique organ,” Dr White said in a statement.
He said it was possible for nerve cells to be “lost” in this part of a person’s body.
“It is possible that the sensory nerves from the perinasal area are lost to the brain, and we will be able study this in future,” he said.
