"We need to invent medical terms for the things eyes do." "Should we give them very similar sounding names so they are easily confused with one another?" "Well, obviously."

I, too, hear it correctly. Proper terms are used for eye movements in this video. It might be helpful to have these terms displayed on the video screen as you speak, especially

in what circumstances would you, or CAN you, rotate an eyeball as with incyclotorsion?
@benporter90695 жыл бұрын
A bit late, but for the sake of others to see and understand I will answer this. The best example of this would be if you tilt your head to one side (i.e. your ear towards your shoulder) - you will notice that the image you see stays vertical despite your head having turned. This is because as you tilt your head away from the mid-line, the eye intorts, i.e. turns the opposite way, from the direction that the head has turned, such that the eyeball remains vertical and the image is vertically preserved. This is the same idea as when you move your head from side to side but fix on a point in the distance, your eyes turn the opposite way to your head movement to keep the image central. This is called the vestibulo-ocular reflex, and involves sensors in the ear, for those interested! Hope this helps!

@AmethystWoman12 жыл бұрын
I could be wrong and you seem to be the expert however, it feels to me that you have the adduction and the abduction labels mixed up. ABduction is "moving away from the midline" and ADDuction is moving towards the midline. When the "dummy" moves his eyes "outward" you call it ADDuction when I believe it's actually ABDuction. (unless the pupil moving is not what you are referring to - unless it's something else inside the eye that is "moving towards" when the pupil moves away from the midline?

@AmethystWoman12 жыл бұрын
BTW, I am an RN. The way I always remembered this when I was learning medical lingo was to think "when a person is ABDucted, they are "taken away" - so ABDuct is "away" from the midline of the body. You are however consistent. It seems to me each time you use the two words you use them backwards? If I am wrong, please explain? thanks. Hate to have folks learning exactly the opposite of what is true by this video.

@davidlopes273 жыл бұрын
for those confused about intosion and extorsion, I can explain. when the eye is already looking at one of the sides, these muscles help moving the eye superiorly and inferiorly, and when your eye is already at one of the sides the superior and inferior rectuses cant act alone in order to move the eye, so then we need these suporting muscles.

There is no God except Allah, prophet Muhammad is the messenger of Allah ❤️🌸 Jesus (Peace be upon him) never said that he is God, the Quran says: And [beware the Day] when Allah will say, “O Jesus, Son of Mary, did you say to the people, ‘Take me and my mother as deities besidesAllah ?'” He will say, “Exalted are You! It was not for me to say that to which I have no right. If I had said it, You would have known it. You know what is within myself, and I do not know what is within Yourself. Indeed, it is You who is Knower of the unseen. 117. I said not to them except what You commanded me - to worship Allah , my Lord and your Lord. And I was a witness over them as long as I was among them; but when You took me up, You were the Observer over them, and You are, over all things, Witness. 118. If You should punish them - indeed they are Your servants; but if You forgive them - indeed it is You who is the Exalted in Might, the Wise. (Holy Quran 5:116-118) .
