1. A perception is when sensory impulses are interpreted in the brain, such as touching a hot stove. A sensation is when the brain becomes aware of a stimulus, such as pain.
2. Pain receptors are excited by any type of tissue damage.
3. Referred pain is a phenomenon when you feel pain in an area other than where the pain originates from.
4. The thalamus and cerebral cortex are the parts on the brain that interpret pain impulses. The thalamus establishes the awareness of pain, and the cerebral cortex verifies the severity of the pain, discovers where the pain is coming from, and responds to the pain.
Five Special Senses
1. Sense of Smell
The olfactory organs of the nose are linked with the sense of smell. To aid in food selection, the …show more content…
These taste buds have cells that contain taste hairs. Taste hairs have receptors in which chemicals are bound and impulses are stimulated. There are five primary taste sensations: sour, sweet, bitter, salty, and umami. Only one of the five tastes is detected by a single taste receptor cell. The sensory impulses from these cells travel on fibers of the glossopharyngeal, facial, and vagus nerves to the medulla oblongata.
3. Sense of Hearing
The ear is associated with the sense of hearing. The inner ear, also known as the labyrinth, has two parts called the osseous and the membranous labyrinths. The cochlea is a part of the labyrinths that functions in hearing. Hearing receptors in the spiral organ are excited by vibrations in the inner ear fluids. The middle ear has auditory ossicles that conduct sound waves to the oval window of the inner ear from the eardrum. Sound waves of vibrating objects are accumulated by the outer ear.
4. Sense of Equilibrium
The vestibule of the ear functions in static equilibrium. When motionless, the head and body’s stability is maintained by static equilibrium. The labyrinth’s three semicircular canals function in dynamic equilibrium. When moved or rotated, the head and body is balanced by dynamic …show more content…
There are many reasons for this. First and foremost, it is because I would never want to live without my sight or hearing. I love going new places, taking pictures, and simply enjoying looking at all of the things that the world has to offer. Without my sense of sight, I would be unable to do that. As far as hearing goes, I would hate to live without it as well. Ever since I was a little girl, I have loved listening to music. I listen to music all of the time now, and can’t imagine how life would be without it. Also, hearing is essential to speaking. If I was deaf, I would have to use sign language in order to speak to another person. It wouldn’t be the worst thing in the world, but I would much rather lose my sense of
