Tucked in the corner of David McGraw's yard is a vision he says he'd by no means noticed before, until recently. "I kinda leaned my head back in my recliner and I turned and as I turned my head I appeared straight via my doorway … David suggests he is a …

Thank you. It’s been very helpful :)
thank you .
thanks bro
Ciliary muscle contraction actually gives lens more spherical shape. Very
helpful vid by the way. Thnx
@Interactive Biology Hey I really appreciate your work. I’ve gained a lot
from them and thanks for that. Btw I wanted to mention that @ 4:39, you’ve
incorrectly said that rods and cones are ‘pigments’. They are cells that
contain pigments and not pigments themselves… I request you to annotate
or edit the video so that no one else points this out to you again…
Once again thanks for your videos…
Thank lord that I watched this vid right before my test and it showed up on
one of the questions!!!!!!!!!!!!! Thank you thank you thank you!!!!!!!!!
do you have any videos about the endocrine system and the hormones of the
body?
Rods and cones are light-detecting cells not pigments, pigments are inside
those cells.
what pisses me off in science is they throw around a lot of words and just
tons of nominal information and treat us like retards- the explanations for
how things truly work are never satisfying and i dont get how anyone can be
satisfied with this garbage if they truly want to understand how things
work unless they really are that retarded
THANK U THANK U THANK U ….I READ A MILLION TIMES IN D BOOKS BUT THE
HEART, EAR AND EYES NEVER MADE MUCH SENSE TO ME….BUT YO VIDEOS DID!!!
@afrprincess07 … would bulge to make the light refract more. This way,
you can distinguish things in greater detail that are closer to you

@jimmyt1222 I’m glad you are loving the videos, and good to know they go
along with your textbook well. I will definitely keep em coming. Just make
sure you keep coming back to check them out
Thanks very much. love the videos. Please keep them coming. You seem to be
following my behavioral neuroscience textbook perfectly. These videos are a
perfect compliment to reading the book and going to lecture. Thanks again.
whre a u frm leslie u da best
@jimmyt1222 That is correct. I should have said photoreceptors there. In
the Fovea is where you have the most cones. However, the pigments are in
the photoreceptors, so you will also have more pigment indirectly. Thanks
for asking.
@afrprincess07 the lens causes the change of direction of light
(refraction). So if the lens is quite thin, the light doesnt pass through
much of the lens and so it would not get refracted as much. This is usually
the case if you are looking at things which are far from you. However if
you need to focus on, say a book, you effectively need to see “bigger”
items (i.e. a diagram on a book as opposed to a cloud in the skywhich
appears smaller). So to accomodate for this closer image, the lens …
This is great! i love it!!!!
senang bisa menemukan video ini. sangat memabntu. sukses untuk kalian!! n_n
Cones and Rods are not “pigments”. They are photoreceptor cells.
When you say “pigment”, do you mean “photoreceptor”? @6:10
MUSTARD LIBIDO!
this helps for my psych class
and skin lesson
question? im still confused on how the lens bends the light to focus on the
retina? why is it that when the muscles expand the lens, the light is able
to be focused on the retina as opposed to when the muscles constrict and
therefore buldges the lens? im not sure if my question makes sense??
