The Fundamentals of Pheromones

In this article, I will discuss the fundamental of pheromones.

Types of Pheromones

Did you ever wonder why dogs mark their territory or why a certain scent will trigger a memory? Well, it’s all related to chemical messengers called pheromones. In mammals and insects, there are different types of pheromones. For example, ants alarm pheromone. These pheromones help them to defend and protect their colony.

And dogs have dispersal pheromones in their urine, which help them mark their territory. But, the fascinating pheromones are a subcategory of the aggregation pheromones called sex pheromones. Sex pheromones are released by both male and female species. Females release them into the environment and males use chemoreceptors to says, follow me with a female. These are ultimately used for mating.

For instance, females silkworms release a sex pheromone from a gland in their abdomen. Male silkworms then detect this with their antennas. In mammals, sex pheromones also play a large role in reproduction. For example, female golden hamsters secrete a potent vaginal discharge during their period of high sexual receptivity. This discharge excites the mail and results in mating.

Mechanism of How Pheromones Work

Compared to other animals, we tend to think of humans as having a very poor sense of smell. Dogs have over 300,000,000 smell receptors in the nose where humans only have 6,000,000. But the human nose can give a surprising amount of information, even giving us an insight into the emotions of other people. When we breathe in, air contacts the skin in our noses which contains millions of receptors. Within the human nose, we can find up to 400 different types of smell receptors, which can detect a trillion different smells.

Through the system, smells can trigger emotions and memories, and they can also help us to experience the feelings of others. When are sweating, we release hormones or pheromones from our sweat and the olfactory system can detect these hormones. And this gives us an indication of whether there's something dangerous in the area. Learn more at http://astrobiosociety.org

Can Pheromones Detect Fear?

When our olfactory system detects these hormones, it causes our fear center to become active. These circulating fear hormones in the air almost making fear contagious because someone else's fear can make you feel it. In fact, if we take sweat samples from people who are about to take their first skydive and get people on the ground to smell their samples there amigula becomes active.

Interestingly, if you take sweat samples from people watching funny films and scary films, volunteers who smell the sweat samples can tell you that they smell different. They can't tell you why. So even though humans have an inferior sense of smell in comparison to other animals, our noses are giving us more information that we think.

Not only does our sense of smell help us detect an edible food or dangerous chemicals, it gives us an insight into the people around us. A smell can actually prevent incest and you heard me correctly. Our genetics influence the chemicals we give off in our sweat giving us all personal odors. Therefore, we smell similar to our family members and there's an inbuilt evolutionary safety mechanism. Learn more at https://jail6letter.wordpress.com

Our sense of smell can help us to detect or family members because this will help us find a suitable mate. Our personal odor gives us an indication of how genetically similar we are to prevent inbreeding. This is why we're more likely to be attracted to people who smell completely different to us.
