| Question | Answer |
| What determines how a sensation is experienced. | "It depends on which part of the brain receives the impulses" |
| ________ is awareness of a stimulus. | "Sensation" |
| The conscious awareness of sensations is ________. | "Perception" |
| What part of the brain understands" a stimulus?" | "Cerebral Cortex" |
| T / F Pressure and touch receptors adapt quickly. | "True" |
| T / F It takes some time for receptors in muscles and joints that report on body position to eventually adapt. | "False - They never adapt" |
| T / F Most sensory receptors stop responding when continuously stimulated, leading to a decrease in the awareness of the stimulus | "True - Most do, but there are exceptions" |
| Names of the Mechanoreceptors that detect touch include: 1. Merkel disks 2. Meissner's corpuscles 3. Pacinian corpuscles 4. Ruffini corpuscles Select all that apply | 1. Merkel disks 2. Meissner's corpuscles |
| Name of the Mechanoreceptor that detects light touch 1. Merkel disks 2. Meissner's corpuscles 3. Pacinian corpuscles 4. Ruffini corpuscles Select all that apply | "1. Merkel disks" |
| Which Mechanoreceptors are encapsulated nerve endings that tell us where we have been touched 1. Merkel disks 2. Meissner's corpuscles 3. Pacinian corpuscles 4. Ruffini corpuscles Select all that apply | "2. Meissner's corpuscles" |
| Which Mechanoreceptors sense first pressure or vibration 1. Merkel disks 2. Meissner's corpuscles 3. Pacinian corpuscles 4. Ruffini corpuscles Select all that apply | "3. Pacinian corpuscles" |
| If a pressure stimulus continues to a given area it is detected by: 1. Merkel disks 2. Meissner's corpuscles 3. Pacinian corpuscles 4. Ruffini corpuscles Select all that apply | "4. Ruffini Corpuscles" |
| T / F Free nerve endings are found in the superficial tissues of the body. | "False - All tissues of the body" |
| What triggers free nerve endings? | "Damaged tissue releases chemicals that the free nerve endings respond to." |
| If you have a heart attack you will probably have pain in the chest and left arm. What is this pain referred to as? | "Referred pain" |
| A child has a fever, pain in the right lower abdomen and elevated white blood cell count. What is the likely diagnosis? | "Appendicitis - That is the site the appendicts refers pain to" |
| T / F The sclera is the transparent area of the eye which allows light penetration. | "False - Sclera is the white of the eye. The cornea is transparent." |
| T / F The Iris regulates pupil size. | "True" |
| The nutrients supplied to the eye by blood vessels are delivered to a structure called the ______. | "Chorid" |
| T / F There are more cones in the eye than there are rods. | "False - There are more rods." |
| In poor lighting, we depend more on rods than we do cones. | "True - There are many more rods and they provide greater resolution." |
| There are 3 type of cones in the eye. They detect which 3 colors. | "Red, Green, and BLUE (RGB) |
| Sound waves can be viewed on an oscilloscope. When the cycles are closer together the pitch will be 1. Higher Pitch 2. Lower Pitch | "1. Higher Pitch - In music this would be the treble cleft. In singing it would be soprano." |
| Sound waves can be viewed on an oscilloscope. When the height of the cycles is shorter the amplitude will be 1. Less volume (quieter) 2. More volume (louder) | "1. Less volume (quieter)" |
| Name the 3 bones in the ear.scientific names). | Malleous Incus Stapes |
| The smallest bone in the human body is the | "Stapes" |
| The bones in the ear have 3 common names that might make you think of a blacksmith. What are the 3 common names. | 1. Hammer (Malleus) 2. Anvil (Incus) 3. Stirrup (Stapes) |
| List the sequence of events that make hearing possible in order of their occurrence. | 1. Movement of the stapes 2. Movements of the fluid 3. Swinging presses projections on the hair cells 4. Bending of the hair cells alters the rate of nerve impulses |
| A A child looses most of the hearing in one ear suddenly without a reason. There are no signs of infection or trauma. His mother takes him to the doctor who examines his ear. The doctor removes a bean from down deep in the ear canal with some tweezers. The boy's hearing is restored immediately. Which of the 2 types of hearing loss did he have? | "Conductive - His ear canal was plugged up by the bean and did not allow sound to vibrate the ear drum." |
| John has always liked his music loud. By the time he is in his forties he is having a noticeable reduction in hearing. He sees an audiologist that explains he has a sensorineural hearing lost and he can only help him a limited amount. He has damage because it has affected 2 parts of the anatomy of the ear. Name them. | 1. Hair cells 2. Nerve supply |
