Example Of Perception Research Paper

Good Essays
The other day, I was thinking about how amazing it is to be able to perceive the world around me. I understood that from the retina to the brain, perception goes from complex to extremely complex. In other words, being able to experience the real world is one of the marvelous opportunities that we have. This phenomenon starts with light getting in contact with the cornea continuing to the back of the eyes, to the retina, before light goes to the optic nerve and end up in the brain. This process appears to be simple; nevertheless, each little section of the eyes plays a huge role in perception and become indispensable for accurate vision. For example, in the retina alone, rods and cones play a big role in perception. There are two types of photoreceptors in the human retina, rods and cones. Rods are responsible for vision at low light level and cones activate when light reaches a higher level. Rods do not mediate color vision; …show more content…
Sound is the vibration of objects. We perceive sound as the ear drums move from the sound pressure. Then, this vibration is transformed into electrical impulses, which are sent to the brain. The transformation of the electrical impulse occurs inside the outer, the middle and the inner parts of the ears. The outer ear is called the external sound-gathering part of the ear. Its function is to gather sound energy and focuses it on the eardrum. The middle ear, an air-filled chamber serves as an amplifier of vibration. The inner ear is where the cochlea is located and also where we perceive sound. While cochlea plays an important part in hearing perception, how sounds move from there to the brain is even more complicated. The vibration of the membrane moves the hair, which sends signals to the roots, the spiral ganglia, the cranial nerve and then the brain. These impulses, when interpreted by our brain, lead to

    The dendrites are branch like bushy extensions that receive the information and conduct impulses towards the cell body. The soma, or cell body, makes sense of the information and works It out. It also triggers the action potential and all or nothing response. The axon is a neuron’s extension that sends messages to other neurons or to muscles or glands. It transmits the Impulse, aka the action potential.…

    Special neurons send messages about the movement of the muscles. Balance and the tracking of body movement is created by the vestibular system, fluid in the ears. The fluid is in sac that connect with the cochlea where the movement sends signals to keep the body up right. The feeling of pain is used to…

    The midbrain acts as a relay station for auditory and visual information (Kumar, 2012). Not only does the midbrain control auditory and visual systems, it also controls eye movement. The midbrain has two main parts the tegmentum and the tectum. The Tegmentum is located within the brainstem and forms the base of the midbrain.The tegmentum consists of the reticular formation, periaqueductal grey matter, and the red nucleus. The reticular formation is involved in sleep, arousal, attention, and other basic reflexes.…

    As sound waves enter the ear, they travel through the outer ear, the external auditory canal, and strike the eardrum (tympanic membrane) causing it to vibrate. The central part of the eardrum is connected to a small bone of the middle ear called the malleus (hammer). As the malleus vibrates, it transmits the sound vibrations to the other two small bones (incus, stapes) or ossicles of the middle ear, the incus and stapes. As the stapes moves, it pushes a structure called the oval window in and out. This is passed onto the cochlea, which is a fluid-filled snail-like structure that contains the receptor organ for hearing.…

    They interpret incoming sensory information. In the sensory division nerve fibers convey impulses to the Central Nervous System while the motor division carries impulses from CNS to effector organs, muscles, and glands (Marieb 2003). The neuron’s anatomy consists of the cell body (also known as the metabolic center of the cell) which contains the nucleus and abundant in nissl substance and neuro-fibrils. There are also the fiber…

    “General senses are those with receptors widely distributed throughout the body, including skin, various organs and joints” ( ,Pg. 444). “Special senses have more specialized receptors and are confined to structure in the head, such as eyes and ears”( ,Pg.444). Over time, scientists have discovered that each little receptor places a different role. “A raw form in which these receptors send information to the brain is called sensation”( ,Pg 444).…

    It is composed of two hemispheres. They manage input from the sensory systems which make connections between various stimuli such as associating what we see with what we hear. In other words, it provides comprehension. When people learn, the structure of nerve cells in the neocortex are changed. The structure of the neocortex is very complicated.…

    Speech is produced as the air is flowed from the lungs moving in and out. The vital organs that are involved to make this process possible are the lungs, larynx, and pharynx, oral and nasal cavities (Honda 2003). These organs make up the vocal tract. According to Mahendru (2014), he stated that acoustic air waves are formed from the lungs that provide the air force to bring about sound. The sound starts its journey from the lungs that goes through a number of channels and makes its exit through the mouth and nasal cavities.…

    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.…
