What is the 4th Sense

Waiting to passIn responding or responding to stimuli that come from outside, the human body needs tools that can help respond to these stimuli. The organs of the body are called the senses. Humans in general have five (five) senses that are very functioning in responding to stimuli. The five senses that function well will make it easier for our bodies to respond according to desires or instincts. Therefore, these five senses can be said to be organs of the human body that can connect the brain with other body parts. Members of the human body will respond according to what is ordered by the brain. However, do you know what the five senses in humans are and what are their functions? In this article, the discussion of the five senses will be discussed in more depth. So, happy reading and see the explanation of the five senses below. The first five senses that will be discussed are the senses of sight or eyes. These eyes are located on the part of the human face which is located below the forehead and there is a right and left nose. These eyes are needed by humans in sending stimuli to be sent to the brain.

For some people to see or focus on objects requires glasses.

As we know that the main function is to see, but if it is discussed more deeply, then the function of the eye is quite a lot. The following functions of the eye, in addition to seeing. When looking at objects that are near or far, clear vision is needed in order to be able to present what object is being seen. For some people to see or focus on objects requires glasses. This is because the person's eyes are unable to focus on objects that are farther or nearer. Light entering the eye must be adjusted because excessive light entering can damage the eye. In addition, the light adjustment of the eyes can be used to see the time, whether it is morning, afternoon, evening, or night. Contact eye maybe you've heard the term. Contact eye can be said as a communication that is done through the eyes. For some people will know the behavior of others just from eye contact only. One of the behaviors that can be seen with eye contact is lying. Do you know what structures are in the eye? If not, this article will discuss the structures of the eye. Here's an explanation of the structures of the eye that you need to know. The sclera is the part of the eye that covers the entire eyeball, except for the cornea. The sclera is composed of connective tissue with strong fibers and is slightly opaque white in color. The sclera is the part of the eye that is impermeable to light. The choroid is the middle layer of the eye that contains blood vessels.

This bone in the retina is called the orbital bone.

Blood vessels function to provide nutrients and oxygen to the eye, especially the retina. This choroid is dark in color because it serves to protect the eyeball from various kinds of interference, such as excessive light. The retina is the part of the eye that is in the form of a layer and is very sensitive to light stimuli. All parts of the retina have connections with nerve cells whose fibers can make up the optic nerves whose shape extends to the brain. In the retina there are bones where the bone serves as a protector of the eyeball as well as the location of the eye. This bone in the retina is called the orbital bone. The lens is the part of the eye located behind the iris and pupil. This part of the eye functions to focus light and objects on the retina. The lens has a flexible and transparent network. If you wear glasses, then it is certain that your eye condition is nearsighted or farsighted. The iris is the part of the eye or the eyeball that is located on the cornea. While the pupil is the eye muscles that can shrink and enlarge or close and open when there is incoming light. Basically the function of the iris and pupil is the same because the two parts are related to each other.

The cornea is the part of the eye that is shaped like a transparent dome.

The function of the iris and pupil is to adjust the light that enters the eye. The macula is the part of the eye in which the center of the eye is responsible for clearer vision. In addition, the macula also functions as a light receiver. The cornea is the part of the eye that is shaped like a transparent dome. In addition, the cornea functions as the outermost part of the eye and as a doorway for light to come in and out. The second sense panda that will be discussed is the sense of hearing or commonly called the ear. The ear has a special ability to recognize various kinds of sound vibrations as well as maintain balance. The function of the ear is divided into two, namely listening to sound and body balance. Function to listen and recognize sounds. The sound that can be heard by humans is 20 Hz to 20,000 Hz. If humans listen to sounds more than 20,000 Hz, the eardrum will burst. In this case, the balance in question is the information received by the ear can be conveyed to the brain in a balanced way. Thanks to this balance function, changes in the speed of sound can be handled properly. Ears become a place of jewelry by piercing.

The auricle has a function to receive or respond to sounds in the environment.

Jewelry that is placed on the ear has been around for a long time, especially in women. The structure of the ear is divided into three parts, namely the outer, middle, and inner parts. The outer part of the ear is the part of the ear that functions to receive various kinds of sound vibrations. In this middle part there are two ear organs, namely the auricle and the ear canal. The two organs have different functions, but are related to each other. The auricle has a function to receive or respond to sounds in the environment. The shape of this auricle is irregular and in this auricle organ there is cartilage and fibrous tissue. The ear canal has a function to convey sound vibrations to reach the tympanic membrane. This ear canal has a size of about 2.5 cm and the outer third of the ear canal is cartilage and the other two thirds is in the form of bone. The middle ear is a small chamber that contains air and contains the eustachian tube.

This part of the middle ear functions to transmit sound vibrations from the outer ear to the inner ear. The sound vibrations are associated with pharyngeal receptors in the ear. Not only that, the middle ear also has three auditory ossicles, namely the hammer (malleus), the anvil (inlus), and the stirrup (stapes). The hammer and the anvil move as one bone because they are bound together by ligaments. The inside of the ear is the part in which there are many organs that can help the way the ear works. The inner ear is composed of a bony labyrinth and a membranous labyrinth. This membranous labyrinth has five main parts, namely three semicircular canals, the utricle, the saccule, the cochlea, and the ampulla. The third sense that will be discussed is the sense of touch or skin. It seems you already know that this skin is the outermost part of the human body. With this skin we will feel various things. In fact, the skin can be used as a protector of the human body from various kinds of disorders. Apart from being a touch tool, the skin also has other functions that can be useful for the human body. These functions will be described below.

With the release of sweat, the heat in the body will decrease.

As a place of sweat. Sweat that comes out of the skin is the result of evaporation taken from the heat around the body. With the release of sweat, the heat in the body will decrease. Sweat contains water and salts. In addition, sweat has two glands that can help the process of sweating out of the skin. First, the eccrine sweat glands, these glands are located all over the body surface, but are usually most abundant on the palms of the hands, soles of the feet, and face. Second, apocrine sweat glands, these glands are located in the armpits and around the genital area. Apocrine sweat glands generally have an unpleasant odor because they come from bacterial activity that is broken down by organic components. If you ask where part of the human body fat is stored, then the answer is skin. Fat that is stored in the skin is in a layer of skin called the hypodermis which is located at the bottom of the dermis layer of skin. The hot human body temperature will be lowered by sweating. And vice versa when the body temperature is cold, the body's warmth can be felt by the skin. Sunlight will produce UV A and UV B, both contents are the result of solar radiation.

UVA rays are solar radiation that can penetrate the skin to the deepest part. The structure of human skin consists of three parts, namely the epidermis, dermis, and hypodermis. For more details, see the explanation as follows. The epidermis is the outermost layer of the skin, which is made up of the corneum and malpighian layers. Corneum layer is a layer of skin that is dead and can be peeled off, then replaced with new skin cells. Meanwhile, the malpighian layer is a layer of skin formed from the spinosum layer and the germinativum layer. In addition, the malpighian layer contains the pigment melanin which can give color to the skin. In other words, the color of human skin depends on the melanin content. The middle layer of human skin is called the dermis. Within the dermis layer are blood vessels, nerve endings, hair roots, sweat glands, and oil glands. These sweat glands will produce a lot of sweat, even every day the sweat released can reach 2,000 ml. At very high temperatures or heat, these sweat glands will become active and the capillaries in the skin will widen. When the capillaries, the process of removing water and metabolic waste becomes easier. The deepest layer of human skin is called the hypodermis and is below the dermis layer. The fat contained in this layer is very much. Stored fats function as food reserves, retain body heat, and protect the body from various kinds of impacts. The fourth sense that will be discussed next is the sense of smell or nose.

The air that enters the nose if not filtered will be very dirty.

The nose is located between the senses of sight or eyes. This one sense tool is very important, especially in smelling aromas. The nose in humans has 3 functions, namely as a means of breathing, smelling, and filtering the air. As we know that the respiratory system must begin with the nose. After the air enters the nose, it will then enter the lungs. From the lungs, the process of circulating oxygen will occur. You certainly already know that when you smell an aroma, whether it's delicious or not, it's definitely through your nose. Therefore, it can be said that the nose is the five senses that function to smell odors. The nose can smell because it has odor receptors. The location of this receptor is in the nose or more precisely in the olfactory nerve. The air that enters the nose if not filtered will be very dirty. Therefore, the nose has hairs that function to filter incoming air. In addition, in the nose there is also a mucous membrane whose function is to moisturize the nose. The structure of the nose is divided into two parts, namely the inner nasal cavity and the upper nasal cavity. The inner cavity of the nose has a septum separating the nasal cavity, the septum is divided into two parts, right and left.

The inner nasal cavity is also divided into three locations, namely the roof of the nasal cavity, the lower nasal cavity, and the side of the nose. At the top, lined with a thin plate. Meanwhile, at the bottom lined with the roof of the nose. For the sides of the nose lined with nasal coral. The upper nasal cavity has the main function of smelling odors. In short, the smell that is smelled will then be received by the smelling mucus that has receptors. From the smelling slime it will proceed to the smelling bubble. From here the smells will be received or responded to by the brain. The last five senses that will be discussed are the sense of taste or tongue. The tongue is an organ of the human body that is located in the mouth or more precisely at the bottom of the mouth. The tongue is an organ that has bones which only consist of a collection of muscles. There are three functions of the tongue in humans, namely as a taster, turning food over, and forming letters. The main function of the tongue is to taste. Just imagine what it would be like if humans didn't have a tongue, they certainly wouldn't know the various flavors that exist. The tongue can feel five kinds of taste, salty, spicy, sweet, bitter, and sour. When you are chewing food, the food is usually turned over. This is because to facilitate the process of mastication and help to swallow food. When someone mentions a letter, it definitely needs the help of the tongue. One of the letters that really needs a tongue is the letter "R". These special receptors are closely related to chemical stimuli. At these receptors the surface is lined with a layer of epithelium and inside the special receptors are contained mucous glands and taste buds. Taste buds on the tongue can reach 10,000, isn't that a lot? The taste buds on the tongue are formed from clusters of sensory cells in which there are protrusions or papillae. This bulge is located on the upper surface. These protrusions can be categorized into several forms, namely thread shape (circumvalata), plain form (foliata), and mushroom form (fungiformis).
