| Question | Answer |
|---|---|
| detect changes and generate impulses | receptors |
| respond by generating electrical impulses | receptors |
| transmit impulses from receptors to the CNS. they are found in both spinal and cranial nerves | sensory neurons |
| white matter in the spinal cord or brain that transmits the impulses to a specific part of the brain | sensory tracts |
| most in the cerebral cortex. feel and interpret sensations | sensory areas |
| the sensation seems to come from the area where the receptors were stimulated | projection |
| pain felt where there are not longer receptors present but the severed nerve endings continue to generate impulses | phantom pain |
| the degree in which the sensations are feltthe brain counts the impulses | intensity |
| the effect of a previous or simultaneous sensation on a current sensation. | contrast |
| becoming unaware of a continuing stimulusexample wearing a watch and not feeling it | adaptation |
| the sensation remains in the consciousness even after teh stimulus has stopped.example watching a bright light go off and still seeing the light in the darkness | after-image |
| receptors for pain heat and cold | free nerve endings |
| receptors for touch and pressure | encapsulated nerve endings |
| provide us with information about the external enviornment | cutaneous senses |
| damage to nerves that impairs sensation sometimes develops in people with diabetes | neuropathy |
| the sensory area for skin | parietal lobes |
| receptors for taste are found in | taste buds |
| most are in papillae on the tounge | taste buds |
| detect chemicals in solution in the mouth | chemoreceptors |
| in the mouth chemicals are | food |
| in the mouth the solvent is | saliva |
| sensory areas for the skin are in the | parietal lobes |
| five types of taste receptors | sweet, sour, salty,bitter and savory |
| is a taste like grilled meat | savory |
| impulses from taste buds are transmitted by the to the taste areas in the parietal -temporal cortex | facial and glossopharyngeal nerves |
| the thin membrane that lines the eyelids | conjunctiva |
| inflammation of the conjunctiva | conjunctivitis |
| produced by the lacrimal glands | tears |
| an enzyme that inhibits the growth of bacteria on the wet warm surface of the eye | lysozyme |
| most of the eyeball is within and protected by the | orbit |
