From childhood, we are taught that the human body has five senses. I’m sure we can all recite them: sight, hearing, touch, taste, and smell. To most people, a “sixth sense” refers either to one outside the realm of the scientific, or one that simply does not exist in most humans. …

Broadly, these sensations can classify into two categories. General sensations which include touch, pain, temperature, proprioception, and pressure. Special Senses: Vision, hearing, taste, and smell which convey sensations to the brain through cranial nerves.

So our nine main senses are:

• Vision.
• Hearing.
• Smell.
• Taste.
• Touch.
• Balance.
• Proprioception (body awareness)
• Temperature.

Sight, Sound, Smell, Taste, and Touch: How the Human Body Receives Sensory Information.

By far the most important organs of sense are our eyes. We perceive up to 80% of all impressions by means of our sight. And if other senses such as taste or smell stop working, it’s the eyes that best protect us from danger.

The Sixth and Seven Senses: The Vestibular and Proprioceptive Systems. You probably first heard of the five senses in kindergarten. However, there are two more senses that don’t typically get mentioned in school — the sixth and seventh senses – that are called the vestibular and proprioceptive systems.

Smell

Taste is a sensory function of the central nervous system, and is considered the weakest sense in the human body. The sense of taste begins with the taste buds, which are found in large bumps on the tongue called fungi form papillae.

Consequently, humans can distinguish between a vast number of scents. We can even track scent trails, provided it’s the right odor. We actually outperform dogs on some scents, like certain aromatic molecules in coffee. And, indeed, we can smell blood.

Why indeed smell is so powerful? One reason is that olfactory system is located in the same part of our brain that effects emotions, memory, and creativity. And, that part of the brain processes smell, interacts with regions of the brain that are responsible for storing emotional memories.

“Healthy” periods can have a slight smell of blood. They may even have a slight metallic smell from iron and bacteria. Generally speaking, period odors aren’t noticeable to others. Good hygiene practices can also combat normal period odors and make you more comfortable during menstruation.

Humans can smell fear and disgust, and the emotions are contagious, according to a new study. The findings, published Nov. Most animals communicate using smell, but because humans lack the same odor-sensing organs, scientists thought we had long ago lost our ability to smell fear or other emotions.

Sharks have nostrils that they only use to smell. Sharks do not smell fear, they can smell ANY trace amount of blood from miles away. …

The team found that the smell of fear triggered a heightened response in brain regions associated with fear when inhaled by volunteers in a brain scanner. The research suggests that, like many animal species, humans can detect and subconsciously respond to pheromones released by other people.

Snakes can smell, they can do it better than dogs can. However, they are not as intelligent as dogs, and therefore- they CAN “smell your fear”, but they don’t understand what it means. However, depending on your body language, a snake may be able if you are intending on eating it or not.

What does it mean when your snake keeps staring at you? Your snake might seem to stare if it’s asleep, hungry, or having the stargazing syndrome. All these will depend on your snake’s breed and its behavioral responses. Once you understand your pet, you will be able to tell what it wants to communicate by a stare.

Large birds, wild boars, mongooses, raccoons, foxes, coyotes and even other snakes are a few of the dangers snakes fall prey to. Many people find it surprising that the largest and the scariest snakes can be afraid of anything, but it is true.

Snakes recognize the scent of their owners from pheromones and sweat, and to a lesser extent, vision and hearing. They can distinguish the owner’s scent using their vomeronasal organ, which is tuned to sense pheromones. Snakes can remember this scent.

When urine is highly concentrated, it contains more ammonia and less water. This can cause it to have a strong smell. Urine tends to be more concentrated when a person is dehydrated. This is often the case first thing in the morning or when a person does not drink enough water throughout the day.

Fishy, rotten, or foul-smelling semen isn’t normal. Eating certain foods — like asparagus, meats, and garlic — or drinking a lot of caffeine or alcohol can make your semen smell pungent. Try limiting these foods to see if your semen smell returns to normal after a few days. If so, there’s nothing to be concerned about.

If you notice a fishy odor from your vagina or vaginal discharge, it may be caused by sweating, a bacterial infection, or even your genetics. The most common is cause is vaginitis, an infection or inflammation of the vagina.

Normal vaginal discharge has a mild, musky scent that is not unpleasant. This means that a very slight smell is normal. Any foul (bad) or strong smell, or a smell that is unusual, is a sign that things are out of balance, and that you should get yourself checked out.

Vaginal odour and sex BV occurs when the balance in that all-important vaginal ecosystem is disturbed, allowing a bacterium called Gardnerella vaginosis to thrive. The infection causes a thin, grey discharge with a fishy odour that is more pungent when in contact with semen.

Don’t worry too much about other people noticing the way your vulva smells. Generally other people won’t be able to smell it at all unless they get very close to your vulva, like when you’re having sex, and in that case most people like the way their partners’ vulvas smell.
