Ch. 11 A&P
Palestine - Ch. 11 Sensory (Eye & Ear)
| Question | Answer |
|---|---|
| What is part of the nervous system that detects a stimulus? | Sensory receptor |
| Receptor for taste and smell, detect chemicals in solution | Chemoreceptors |
| Receptor located in the retina of the eye, responds to light. | Photoreceptors |
| Receptor that detects change in temperature. Many of these receptors are located in the skin. | Thermoreceptors |
| Receptors that respond to movement, such as stretch, pressure, or vibration. These include pressure receptors in the skin, receptors that monitor body posistion, and the receptors of hearing and equilibrium in the ear. | Mechanoreceptors |
| A sense from receptors in the eye. | Vision |
| A sense from receptors in the internal ear. | Hearing |
| A sense from receptors in the internal ear. | Equilibrium |
| A sense from receptors in the tongue. | Taste |
| A sense from receptors in the upper nasal cavities. | Smell |
| A sense from receptors in the skin and internal organs. | Pressure, temp, pain, and touch |
| A sense from receptors in the muscles, tendons, and joints. | Sense of position |
| Description of rods of the retina: | Cylindrical, approx. 120 million in each retina, toward the anterior of the eye, dim light, pigments sensitive to purple, color perception(none; shades of gray) |
| Description of cones of the retina: | Flask shaped, approx. 6 million in each retina, concentrated at the center of the retina, bright light, pitments sensitive to red, green or blue, color perception(respond to color) |
| What is called the window of the eye? | Cornea |
| What is it called when you enter into dim light, such as a darkened movie theatre, you cannot see for a short period? | Dark adaptation |
| Color blindness results from a lack of ________________. | Retinal cones |
| The voluntary muscles attached to eyeball's outer surface are the ___________________. | Extrinsic muscles |
| What is the back of the eye called? | Fundus |
| The 1st step to the visual process | 1. Light refracts |
| The 2nd step to the visual process | 2. The muscles of the iris adjust the pupil |
| The 3rd step to the visual process | 3. The ciliary muscle adjusts the lens (accomadation) |
| The 4th step to the visual process | 4. The extrinsic eye muscles produce convergence |
| The 5th step to the visual process | 5. Light stimulates retinal receptor cells (rods and cones) |
| The 6th step to the visual process | 6. The optic nerve transmits impulses to the brain |
| The 7th step to the visual process | 7. The occipital lobe cortex interprets the impulses |
| The 1st & 2nd step to the hearing process | 1. Sound waves enter the external auditory canal. 2. The tympanic membrane vibrates |
| The 3rd step to the hearing process | The ossicles transmit vibrations across the middle ear cavity |
| The 4th step to the hearing process | The stapes transmits the vibrations to the inner ear fluid |
| The 5th step to the hearing process | Vibrations move cilia on hair cells of the organ of Corti in the cochlear duct |
| The 6th step to the hearing process | Movement against the tectorial membrane generates nerve impulses |
| The 7th step to the hearing process | Impulses travel to the brain in cranial nerve VIII |
| The 8th step to the hearing process | The temporal lobe cortex interprets the impulses |
| The taste receptors, known as _________________, are located along the edges of small, depressed areas called____________. | Taste buds, fissures |
| __________________ taste buds are experienced at the tip of the tongue. | Sweet - hence the popularity of lollipops and ice cream cones |
| __________________ taste buds are most acute at the anterior sides of the tongue. | Salty |
| __________________ taste buds are most effectively detected by the taste buds located laterally on the tongue. | Sour |
| __________________ taste buds are detected at t he tongue's posterior part. | Bitter |
| The sense of smell is called ___________________. | Olfaction |
| The touch receptors, ____________________, are found mostly in the dermis of the skin and around hair follicles. | Tactile corpuscles |
| Where are the sensory end-organs for deep pressure found? | Subcutaneous tissues beneath the skin and also near joint, muscles, and other deep tissues. |
| Temperature receptors are called? | Free nerve endings |
| Sense of position receptors located in muscles, tendons, and joints that relay inpulses that aid in judging one's position and changes in the locations of body part in relation to each other are called? | Proprioceptors - they are aided in this func. by the internal ear's equilibrium receptors |
| What is referred pain? | Originates internally but felt at the surface. |
