| Question | Answer |
|---|---|
| Pain. | These receptors are found in the skin and also in muscles, joints, and internal organs |
| Touch, | the tactile sense, located in the skin. |
| Pressure, | deep touch, located beneath the skin and in deeper tissues. |
| Temperature. | Receptors for heat and cold are located in the skin and also in the hypothalamus, which regulates body temperature. |
| Proprioception, | the awareness of body position. Receptors in muscles, tendons, and joints help to judge body position and coordinate muscle activity. |
| Gustation (taste) | located in receptors in taste buds on the tongue. |
| Olfaction (smell) | is located in receptors in the nose. |
| Hearing receptors | are located in the ear. |
| Equilibrium receptors | are also located in the ear. |
| Vision receptors | are light-sensitive and located deep within the eye, protected by surrounding bone and other support structures. |
| equilibrium | The sense of balance |
| gustation | The sense of taste (Latin geusis means "taste") |
| hearing | The sense or perception of sound |
| olfaction | The sense of smell (root osm/o means "smell") |
| proprioception | The awareness of posture, movement, and changes in equilibrium; receptors are located in muscles, tendons, and joints |
| sensory receptor | A sensory nerve ending or a specialized structure associated with a sensory nerve that responds to a stimulus |
| tactile | Pertaining to the sense of touch |
| vision | The sense by which the shape, size, and color of objects are perceived by means of the light they give off |
| auditory tube | The tube that connects the middle ear with the nasopharynx and serves to equalize pressure between the outer and middle ear |
| cerumen | The brownish, wax-like secretion formed in the external ear canal to protect the ear and prevent infection |
| cochlea | The coiled portion of the inner ear that contains the receptors for hearing |
| external auditory canal | Tube that extends from the pinna of the ear to the tympanic membrane; external auditory meatus |
| incus | The middle ossicle of the ear |
| labyrinth | The inner ear, named for its complex structure, which resembles a maze |
| malleus | The ossicle of the middle ear that is in contact with the tympanic membrane and the incus |
| ossicles | The small bones of the middle ear; the malleus, incus, and stapes |
| pinna | The projecting part of the outer ear; auricle |
| semicircular canals | The three curved channels of the inner ear that hold receptors for equilibrium |
| spiral organ | The hearing receptor, which is located in the cochlea of the inner ear; organ of Corti |
| stapes | The ossicle that is in contact with the inner ear |
| tympanic membrane | The portion of the inner ear that is concerned with the sense of equilibrium; it consists of the vestibule and the semicircular canals |
| vestibule | The chamber in the inner ear that holds some of the receptors for equilibrium |
| vestibulocochlear nerve | The nerve that transmits impulses for hearing and equilibrium from the ear to the brain; eighth cranial nerve; auditory or acoustic nerve |
