The nose and smell

The nose is the sense organ of smell. It detects different smells in the air we breathe. At the entrance of the nose, you will find there are two holes called nostrils. They are separated by something called s septum. When you breathe in through the nostrils, the air enters the nasal passage and heads into your nasal cavity. The nasal cavity is a space in your head behind your nose. From the nasal cavity, the air heads downhill though the trachea and ends up in the lungs. Then the whole process happens in reverse when you exhale. Your nose can smell what it smells because of the olfactory epithelium. It contains special receptors that notice smells. Then the receptors send signals along the olfactory nerve. Those signals then go to the brain.

Nevertheless, this is different in aliens. The nose is the sense organ of taste. The aliens introduce the food through their trosnil and then the nasal cavity moves food around it until it is totally a mass. After that, the tastolfact liumepi detect different flavours such as salty, sweet, bitter or sour. Finally, the information captured by receptors in the tastolfact liumepi travels to the brain through the olfactory nerve. The brain receives and interprets this information.

The tongue and taste

The tongue is the sense organ of taste. It detects different flavours. We can detect flavours thanks to the taste buds on our tongue. We have around 100000 taste buds located on the front and back of our tongue. A few basic tastes can be detected by our buds: salty (fish), sweet (cupcakes), bitter (coffee) and sour (lemon). When you eat something, the saliva in your mouth breaks down the food and the taste buds sense the basic tastes. This message is sent to the brain which then detects the right flavour.

Nevertheless, this is different in aliens. The tongue is the sense organ of touch. Aliens do not really know to touch things, so they do not use this sense organ too much. They can feel different types of touch thanks to the tasmo bisd on their tongue. They can detect soft materials, hard materials or flexible materials. The information captured by receptors in the tasmo bisd travels to the brain through the nerves. The brain receives and interprets this information.

Skin and touch

The skin is the sense organ of touch. It detects temperature, pain, pressure, etc. The skin is composed of hair, pore, sweat gland, touch receptors, and nerves. The epidermis is waterproof and serves as a protective wrap for the underlying skin layers and the rest of the body. It contains melanin, which protects against the sun's harmful rays and also gives skin its color. When you are in the sun, the melanin builds up to increase its protective properties, which also causes the skin to darken. The epidermis also contains very sensitive cells called touch receptors that give the brain a variety of information about the environment the body is in. Pores are on the surface of the skin which allows the hair to grow. The hair protects us from the sun and the cold. The second layer of skin is the dermis. The dermis contains hair follicles, sweat glands, blood vessels, nerve endings, and a variety of touch receptors. Sweat glands eliminate waste produced at the dermis level of the skin by opening their pores at the surface of the epidermis and releasing the waste. The bottom layer is the subcutaneous tissue which is composed of nerves. The information captured by receptors in the skin travels to the brain through the nerves. The brain receives and interprets this information.

However, all of this is different for aliens. The skin is the sense organ of hearing. Their soft skin detects sounds and their properties, and where these sounds come from. Because the skin is around all their body, they can detect sounds from far distances, even if they are just whispers. Therefore, this is their most powerful sense organ. The hairlus remain still as guitar sting when they feel the noise, so they can detect it easily. Poaires are on the surface of the skin, which allows the hair to grow. Sweit glennd clean the skin with a special oil in order to make the sound clearer. Then, the information captured by receptors in the skin travels to the brain through the nerves. The brain receives and interprets this information.

Ears and hearing

The ears are the sense organs of hearing. They detect sounds and their properties, and where these sounds come from. What you think is your ear is actually just your outer ear. It shape help us to know which direction the sound is coming from. But in deeper, the ear consists of the ear canal, the middle ear, and the inner ear. The sound moves in the air freely. When the sound waves hit your ear they travel inside your ear canal. The waves travel on until they hit the eardrum in the middle of the ear, which acts quite like a drum. The eardrum is connected to special bones, the smallest bones of your body called ossicles. These bones transmit the waves further to the inner ear.  Your inner ear looks like a spiral full of liquid and tiny hair called cochlea. These hairs move with the sounds and transmit that information to the brain. The information captured by receptors in the cochlea travels to the brain through the auditory nerve. The brain receives and interprets this information.

If you are curious, maybe you want to know that the liquid in your ear helps your body to maintain its balance.

Nevertheless, all of this is different for aliens. The ears are the sense of sigh. They detect light so they can see shapes and colours and estimate distances. The outer ear helps them to adapt their ear canal to the amount of light it is going to receive. The inner ear is really interesting. The eyeye is like a window, because aliens use it to see the world. This light passes though the oseyeos that takes the upside down image from the retina to the brain, which must first invert it and then make sense of it. After that, the coeraye makes colour even brighter and help the ear to see things that were in a far distance. Moreover, the information captured by receptors in the coeraye travels to the brain through the auditory nerve. The brain receives and interprets this information.

Eye and sight

The eyes are the sense organs of sight. They detect light so we can see shapes and colours, and estimate distances. We see and look the world around us, but we never stop to think how. Your eyes are almost like a ball. The circle in the centre of your eye is called iris (can have different colours), the small spot in its centre is called the pupil. The pupil is like the window of a room. The iris can open wide or shut narrow the pupil to let just the right amount of light come inside the eye, so when you are in a dark room, your pupil becomes bigger to let more light in. Nevertheless, if you move to a place with more light, the iris will shrink to allow only the required amount of light. This light passes through the cornea and lens to fall onto the retina. The retina is a super sensitive surface with lots of optic nerve endings. These nerves take the upside down image from the retina to the brain, which must first invert it and then make sense of it. The information captured by receptors in the retina travels to the brain through the optic nerve. The brain receives and interprets this information.

The pupil and the lens continuously keep adjusting so that you can see the clearest image of the world. For some people, these adjustments are not enough but these problems can easily be corrected using glasses.

However, all of this is different for aliens. The eyes are the sense organs of smell. They use them to breathe and to detect different smells in the air. Aliens capture the smell by the nosesenotril, which form is really similar to the pupil. The openbig is like the iris, which allows to make the nosesenotril bigger if the alien wants to breathe or smell something in a deeply way. The smell and the air passes through the neaco and the jint until they reach the natire, which is in charge of detecting bad or toxic smells. Moreover, the information captured by the receptors travels to the brain through the noyese nerve. The brain receives and interprets this information.
