Types of Hearing ImpairmentsNerve hearing impairment can result from:damage in the inner eardamage in the auditory pathways and cortical areas of the brain

Surgery to Help Restore Hearing Cochlear implant: a microphone implanted just behind the ear that picks up sound from the surrounding environmentspeech processor selects and arranges the sound picked up by the microphoneimplant is a transmitter and receiver, converting signals into electrical impulsesCollected by the electrode array in the cochlea and then sent to the brain

SmellOlfaction (olfactory sense)sense of smellOlfactory bulbsareas of the brain located just above the sinus cavity and just below the frontal lobes that receive information from the olfactory receptor cellsAt least 1,000 olfactory receptors

Somesthetic SensesSomesthetic senses: the body senses consisting of the skin senses, the kinesthetic sense, and the vestibular senses“soma”: body“esthetic”: feeling
Background image
Somesthetic SensesSkin senses: the sensations of touch, pressure, temperature, and painsensory receptors in the skingate-control theory: pain signals must pass through a “gate” located in the spinal cord

Somesthetic SensesKinesthetic sense: sense of the location of body parts in relation to the ground and each otherproprioceptive receptors (proprioceptors)Proprioceptionis the senseof the relative position of neighboring parts of the body and strength of effort being employed in movement.
Background image
Somesthetic SensesSensory conflict theory: an explanation of motion sickness in which the information from the eyes conflicts with the information from the vestibular sensesresults in dizziness, nausea, and other physical discomforts
Background image
Somesthetic SensesThe Vestibular Senses: Awareness of body balance and movement are monitored by the vestibular system. The vestibular senses (the sensations of body rotation and of gravitation and movement) arise in the inner ear; the sense organs are the hair cells that send out signals over the auditory nerve.
