5 Five Senses (Physiology): Functions, Images, and Parts
5 Panca Indra (Physiology): Functions, Images and Complete Parts - Every human being has been granted five senses by the creator, so that we can carry out daily activities using the five senses that have been granted by the creator. On this occasion here will be a complete review of the Five Senses. For that, let's look at the reviews below.
Understanding the Five Senses
The five senses are the organs of the body which have a function of knowing external circumstances. The human sense organ is often referred to as the five senses, because it consists of five senses namely the sense of sight (eyes), the sense of hearing (ears), the smell / smell (nose), the sense of taste (tongue) and the sense of touch (skin). The senses are the interface, contact between the soul in the form of spiritual self-awareness and environmental matter. In Hinduism there are eleven types of flavors and are referred to as eka dasa indriya.
Various Kinds of Five Senses
1. Eyes
The eye is the senses whose function is to see the surrounding environment in the form of images, so that the eye can recognize objects that are around it quickly.
The eye is the sense of sight that receives an excitatory form of light (photooreceptors). The eye is composed of eye enhancements, eyeballs, eyeball muscles, and optic nerves II.
This eye enhancement tool has a function to protect the eyes from interference in the environment. These eyebrows function to protect the eyes from sweat, while the eyelids to protect the eyes from collisions and the eyelashes function to protect the eyes from strong light, dust and dirt.
parts of the eye and its functions are as follows:
The cornea of the eye, has the function of receiving a light stimulus and passing it on to the deeper part of the eye.
The eyepiece has a function to continue and focus on light so that the shadow of an object falls into the eyepiece.
Iris has a function to regulate how much or at least a light enters the eye.
Pupils have a function as the entrance of a light.
The retina has the function of forming an image of an object which is then sent by the eye nerve to the brain.
The eye muscles have the function to regulate an eyeball movement.
The eye nerve, has the function to carry on a stimulation of light from the retina to the brain.
The way the eye works is as follows:
The light goes to the aqueous humor then goes to the pupil and continues to the lens then goes to the vetreous humor then goes to the retina then goes to the optic nerve and finally to the brain.
2. Ears
The ear is a sense organ that functions to hear the sounds that are around us. The ear is the sense of hearing which receives a stimulation in the form of sound (phonoreceptors). Another function of the ear is that the ear functions as a balance tool.
Ears
Namely as follows:
The outer ear consists of the auricle, ear hole and auditory canal.
The middle ear consists of the eardrum, 3 listening bones (hammer, foundation and stirrup) and the eustachian tubes.
The inner ear which consists of a body balance tool, three semicircular channels, jorong casement, round casement and cochlea (cochlea)
The function of the listener's senses:
The auricle, ear hole and auditory canal have the function to capture and collect a sound wave.
This eardrum has the function of receiving an excitatory sound and passing it on to a deeper part.
Three hearing bones (hammer bones, foundation and stirrup) have the function of amplifying a vibration and transmitting it to the cochlea or cochlea.
Jorong cage, round cage, three semicircular channels and cochlea (the cochlea) have the function to change impulses and are transmitted to the brain. the Three semicircular channels also have a function to maintain body balance.
Eustachian tube functions to connect an oral cavity with the outer ear.
The way the ear works is as follows.
the auricle then goes to the ear canal then goes to the eardrum then goes to the three hearing bones then goes to the cochlea and then goes to the hair cells in the cortical organ then goes to the audiotory nerve cells and finally to the brain.
3. Sensory Odor (Nose)
The nose is the senses that we use to recognize an environment or something from the aroma produced. Fibers in the olfactory nerve are found in the upper part of the nasal mucous membrane. These olfactory fibers have a function to detect excitatory chemicals in the form of gases in the air (chemoreceptors).
Parts of the nose
namely as follows:
The nostril has a function for the entry and exit of air.
Nasal hair has the function to filter out an incoming air when breathing.
The mucous membrane has a function as a place to attach a dirt and as a sense of smell.
These nerve fibers have a function to detect chemicals present in the respiratory air.
This nerve has a function to send odors to parts of the brain.
How the nose works
is as follows :
Stimulation (odor) goes to the nostrils then goes to the olfactory epithelium then goes to the olfactory mucosa then goes to the olfactory nerve then goes to the thalamus then goes to the hypothalamus and finally goes to the brain.
4. Taste Taste (Tongue)
The tongue is one of the senses that has the function to feel the taste stimulation from food that enters our mouths. The tongue can respond to various types and various flavors such as sweetness, bitter taste, sour taste and saltiness.
On the tongue there are two groups of muscles, namely intrinsic muscles (making a smooth motion) and extrinsic muscles (making a rough movement when chewing and swallowing and linking the tongue to the surrounding parts).
On the part of the tongue that is called a papilla which is the nerve end of the taste bud. Each of these taste buds has a sensitivity to certain tastes based on their location on the tongue. At the base of the tongue can taste the bitter taste, at the edge of the tongue to taste the taste of salt and acid and at the tip of the tongue functions to taste sweet taste.
On the surface of the tongue covered by three kinds of papillae are as follows.
Papilla sirku valata
Filiform papillae
Fungiform papillae
The way the tongue works is as follows:
Food / solution tastes to the papilla of the tongue then to the gustatory nerve then to the medulla oblongata then to the thalamus and finally to the brain.
5. Feeling Touch (Skin)
The skin is one of the senses that is able to receive a stimulus temperature temperature, touch, pain, pressure, texture, and so forth. In the skin there is a receptor that is sensitive to a physical stimulus (mechanoreceptor).
Examples are touch, pressure, pressure, coldness, and pain. These receptors are either free nerve endings or nerve endings wrapped in a connective tissue capsule.
Generally, in each type of receptor can only accept one type of excitement. The skin has a function as an inner protective device, for example in muscles and bones, and as a tactile device equipped with a variety of receptors that are sensitive to a variety of stimuli, namely as an excretion tool and for regulating body temperature.
Skin Parts and Functions:
The epidermis has a function to prevent the entry of a germ of disease and to prevent the evaporation of water from the body.
Sweat glands have the function to produce a sweat.
The layer of fat has a function to warm a body.
Hair movers have the function to regulate a hair's movement.
Blood vessels have the function to drain blood throughout the body.
The five senses are one of God's gifts for humans. and has its own advantages over other living things.
