What is the word that describes when you get used to or noxious smell? Explain why |
Adaptation ; when sense receptor is overwhelmed with stimulus they become less sensitive to repeated stimulus ( first smell something then it goes away |
|

The sense of position or orientation |
|
|
The sense of pain does not undergo adaptation why |
When ice answer scepter is overwhelmed with stimulus they become less sensitive 2 repeated stimulation Decrease response to stimulus will only generate impulse if stimulus is increased |
First smell something and then it goes away or you get used to it chewing gum |
|
Taste receptors |
Salty sour sweet and bitter |
|
|
Taste buds |

|
|
Taste hair |
Microvilli function as receptors |
|
|
The sense of smell is referred to as olfaction and is perceived in what lobe of the brain |
Olfactory sense and is located in the temporal lobe |
|
|
Why can't I taste and smell stuff at the same time |
Chemicals dissolved in liquid are picked by The receptors of taste and smell chemoreceptors |
|
|
Where are tears produced |
Lacrimal glad |
|
|
The sclera is the "white of the eye" and is an extension of which of the three tunic layers of the eye |
Fibrous tunic |
|
|
The transport portion of the fibrous tunic on the anterior surface of the eye is referred to as what |
Cornea |
|
|
What is the bulbous oculi |
Eyeball me |
|
|
What are the three layers of Tunic in the eye |
Fibrous, vascular, nervous |
|
|
Which tunic of the eye is pigmented and very vascular |
Choria |
|
|
Which tunic of the eye contains receptors for vision |
Nervous ciliary |
|
|
The diameter of the pupil is determined by what |
Muscle of the Iris |
|
|
No visual receptors are found in what area of the retina |
Optic disk |
|
|
Rods and cones are found on what tunic of the eye |
Photoreceptors in the retina |
|
|
Refraction |
Bending of light rays |
|
|
List the structures of the eye that refract light |
Cornea, aqueous humor, lens and vitreous humor |
|
|
The first structure in a visual pathway that reflects light is what |
Cornea |
|
|
Why enters the eye first through the cornea then through what structures until it reaches the retina |
aqueous humor, pupil, lens, vitreous humor |
|
|
How does the lens change in near vision |
Bulged and more convex Ciliary muscle contract but suspensory ligaments are relaxed this causes the pupil to dilate |
|
|
How does the lens change the shape to accommodate for far vision |
Flat Ciliary muscles relax but suspensory ligaments are taught- pupil contract |
|
|
Which three color pigment receptors are located on specific photoreceptors |
Green blue and red Cones |
|
|
Color receptors are concentrated in what are of the retina |
Cones |
|
|
What is the relationship between rhodopsin and bright/dim light |

|
|
Rhodopsin is primary related to rods or cones |
Rods- sensitive to light |
|
|
