Question

What are some examples of the five senses?

Answer 1

Hint: To respond, interact, and keep the body healthy and secure, the nervous system must obtain and process information from the outside world. The sensory organs (eyes, ears, nose, tongue, and skin) provide a lot of this detail. These organs contain specialized cells and tissues that absorb raw stimuli and convert them into signals that the nervous system can understand.

Complete answer:
Eyes: The eyes are covered by bone and fat in the orbits of the skull. The sclera is the white portion of the skin. It shields internal organs and forms a circular portal with the cornea, iris, and pupil. The image is then focused onto the retina, the eye's inner layer, by the curved lens. The retina is a fragile nerve tissue membrane that contains photoreceptor cells. The rods and cones are the cells that convert light into nerve signals. The optic nerve transports signals from the eye to the brain, where they are interpreted to form visual images.
Ears: Waves are funneled down the ear canal (the external acoustic meatus) to the tympanic membrane (the "eardrum") by the outer ear. Sound waves reverberate against the tympanic membrane, causing mechanical vibrations. The tympanic membrane transmits these waves to three small bones in the middle ear's air-filled cavity known as auditory ossicles. The spiral-shaped cochlea is located in the inner ear, which is made up of fluid-filled canals. Specialized hair cells in the cochlea sense pressure waves in the fluid as the ossicles pound away. They trigger nerve receptors, which transmit signals to the brain through the cochlear nerve, which interprets the signals as sounds.
Skin: The outer epidermis, middle dermis, and inner hypodermis are the three main tissue layers that make up the skin. Tactile sensations are detected by specialized receptor cells in these layers, which send signals to the brain through peripheral nerves. Certain body parts are more sensitive due to the presence and position of various types of receptors.
Nose: Olfaction is the scientific term for the sense of smell. It begins with specialized nerve receptors on hair-like cilia in the epithelium of the nasal cavity's top layer. Any chemicals in the air bind to these receptors as we sniff or inhale through our nose. This sends a signal up a nerve fiber to the olfactory bulbs, passing through the epithelium and the skull bone above. Neuron cell bodies in the olfactory bulbs relay information to the cranial nerves, which are branches of the olfactory bulbs. They send the signal down the olfactory nerves to the cerebral cortex's olfactory region.
Tongue: Food chemicals penetrate the papillae and hit the taste buds as we feed. These chemicals activate nerve receptors by stimulating specialized gustatory cells within the taste buds. Facial, glossopharyngeal, and vagus nerve fibers receive signals from the receptors. The signals are carried by those nerves to the medulla oblongata, which then relays them to the thalamus and cerebral cortex.

Note:
Proprioception is defined as the “sixth sense” of the body apart from the well-known five senses of the body. It describes the ability to sense the orientation of the body in the environment. In other words, it perceives exactly how our body is in a particular environment.
