Sensory Perception study guide correct and verified A+

Sensory Perception study guide correct and verified A+Sensory Perception study guide correct and verified A+ Sensory perception - correct answer-Refers to tbe provess by which our brian receives,organize, and interprets sensory information from our environent through our 5 senses: Vision Hearing Taste Smell Touch Sensory reception - correct answer-the stimulation of sensory nerve fibers and the transmission of impulses to higher centers within the brain normal sensation - correct answer-- Reception: stimulation of a receptor such as light, touch, or sound - Perception: integration and interpretation of stimuli - Reaction: only the most important stimuli will elicit a reaction Sensory deficits - correct answer-Deficit in the normal function of sensory reception and perception Sensory deprivation - correct answer-Inadequate quality and quantity of stimulation Sensory overload - correct answer-- reception of multiple sensory stimuli • ICU • Burn unit Nursing Knowledge Base - correct answer-• sensory alterations are common in older adults • A loss of sensory input can cause feelings of grief, anger, depression, and loss of self esteem • Self-esteem disturbances can lead to social isolation • Patient education can provide older adults with the necessary skills to cope with sensory alterations Visual system components - correct answer-Eyes Surrounding optic muscles Cranial nerves: II (optic) III (oculomotor), IV (trochlear) and VI (abudcens) External eye structure - correct answer-Eyelid Conjunctiva Lacrimal gland Eye muscles Internal Eye Structures - correct answer-Three layers: : sclera and cornea 2. Middle: lens, pupil and iris 3. Inner: retina Iris and pupil - correct answer-Control the amount of light that enters the eye Lens - correct answer-Bends light rays to ensure they focus correctly on the retina Renita - correct answer-Converts light into electrical impulses Optic Nerve (II) - correct answer-Send these impulses to the brain, allowing us to see External ear - correct answer-auricle, external auditory canal middle ear - correct answer-tympanic membrane and auditory ossicles Inner ear - correct answer-bony labyrinth cochlea Auricle and external auditory canal - correct answer-Collect and transmit sound to the eardrum tympanic membrane - correct answer-Vibrates in response to sound waves auditory ossicles - correct answer-amplify and transmit vibrations to inner ear Cochlea - correct answer-Converts vibrations into nerve impulses Cranial nerve VII - correct answer-Carries impulses to the brain Cerrebellum - correct answer-Helps maintain balance Temporal lobe ( auditory area) - correct answer-Process sound for hearing Taste (gustatory) - correct answer-Chemical stimulation of the taste buds conducted via cranial nerves VII, IX, and X then transmitted to the brain VII facial nerve IX glosspharyngeal nerve X vagus nerve Normal physiological process of smell - correct answer-- Controlled by cranial nerve 1 olfactory - Smell depends on sensory receptor response to airborne chemicals. These receptors are located in the mucous membranes of the upper and posterior parts of the nasal cavity - These chemicals bind to the ciliary receptors in the nose, which trigger a serious of reactions that travel along the olfactory nerve to the brain Touch - correct answer-- The perc
