Sense Organs Definition
“The sensory organs are the organs that respond to external stimuli by transmitting impulses to the sensory nervous system.”
What organs make sense?
The sensory organs are specialized organs that help us perceive the world around us. They are an essential part of our life and this is the only way we can perceive the environment.
The sensory organs provide the data necessary to interpret them from different organs and the nervous network in response to a particular physical phenomenon. These senses determine how we treat and interact with the environment. To diagnose any issue with these senses, tools to examine at home can be kept in the first aid box in your home. For this purpose, you need to keep in contact with the best Medical equipment manufacturers.
We have five senses, namely:
These five senses contain receptors that transmit information through sensory neurons to the appropriate points in the nervous system. The receivers can be divided into two parts. General and special receivers. The former is present throughout the body and the latter includes chemoreceptors, photoreceptors, and mechanoreceptors.
Five sense organs
As already mentioned, we have five senses that can receive sensory information and send it to the brain. These senses provide information to an organism that is vital for perception. The various senses and the senses they provide are listed below:
1. Eyes: vision or ophthalmic reception
These are the organs of the visual senses of our body. They are sensitive to light. The color of the eyes depends on the amount of melanin in our body. Supports vision by recognizing and focusing bright images.
The iris of the eye is the colored part that controls the size and diameter of the pupil, which directly affects the amount of light that enters the eye. The vitreous is behind the lens of the eye. It is filled with a jelly-like material called the vitreous body. This substance shapes the eyeball and transmits light to the back of the eyeball, where the retina is located.
This retina contains photoreceptors that perceive light. Two types of cells perform different functions. These are reed and tang.
Rods – These sensors work in low light conditions and are located on the edges of the retina. They also help with peripheral vision.
Cones – These types of cells in the retina work best in bright light and recognize delicate colors and details. There are three types of cones to capture three main colors of light: blue, red, and green. Most of the time, color blindness occurs when one of these types of cones is absent.
2. Ears: hear or listen
The ears are the hearing senses of our body. They help us detect noise. Our hearing system detects vibrations in the air and this is how we hear a noise. This is called audio or audio subtitles.
The ears are divided into three parts, namely the outer ear, the inner ear, and the middle ear. All sounds are vibrations, so the outer ear transmits these vibrations to the ear canal, where the brain converts these vibrations into meaningful sounds. In addition to listening, this understanding is also important to balance our body or balance. To diagnose ENT issues, Ear light scopes help at home in the best ways if it’s not the hours of a doctor.
3. Tongue: taste or taste
The tongue helps to perceive different flavors and aromas. The taste buds are present between the taste buds of the tongue; help to detect different fragrances.
Smell and taste often work together. If a person couldn’t smell something, he couldn’t taste it. The sense of taste is also called reception taste.
There are taste buds on the tongue and the chemicals work in the same way as the chemicals in the nasal cavity.
However, chemists in the nose would recognize an odor of any type, although there are four different types of taste buds, each of which can identify different types of fragrances, such as sweetness, sourness, sourness, and salt.
4. Nose: olfactory odor or conception
When inhaled, air enters the nasal cavity. Olfactory cells are chemical cells, which means that olfactory cells have protein receptors that can detect small differences in chemicals. These chemicals bind to cilia, which stimulate a nerve impulse that is carried to the brain. The brain then translates these stimuli into a meaningful smell. During a cold, the body produces mucus that blocks odor. That is why the food we eat is delicious.
5. Skin – tactical contact
The skin is the largest organ in our body. It is related to the sense of touch. The sense of touch is also called tactioception.
Receptors are common in the skin that can detect touch, pain, pressure, and temperature. They are present in all the skin. Key number receptors generate impulses and, when activated, travel to the spinal cord and continue to be sent to the brain.
